Initially early farmers simply selected food plants with particular desirable characteristics, and employed these as progenitors for subsequent generations, resulting in an accumulation of valuable traits over time. The local Egyptian cultivars are (Giza 85, Giza 91, Giza 95) and the promising hybrid (Giza 90 × Australian). International Journal of Plant Research, 5, Please attach the details of experimental results at the end and refer to these as, Summary It is concluded from a review of the literature that plant cell culture itself generates genetic variability (somaclonal variation). Russell, W. A. Three diluents prepared using standard procedures were tested as extenders. © 2008-2020 ResearchGate GmbH. In addition, the parent (P 6) was the highest Mokadem et al., 2016-34-parent for fiber strength. The adverse effects of delayed planting dates can be mitigated by forecasting optimum planting dates through crop modeling experiments. Center, Ministry of Agric., Baghdad. variability from cell cultures for plant improvement. All the used genotypes belong to (Gossypium barbadense, L.). So when the estimates were high, culling poor performers on the basis of a single record will be effective in improving flock performance. There is a strong correlation between weed population and maize yield. Among weed species, Rotala indica was found most dominant (1091 m-2) and proportion 18%) followed by Eriocaulon cinereum (245.83 m-2 and 12%). Seed Science and ... Mishra, GBPUAT, Pantnagar; Dr B.D. Body weights of resulted chicks were recorded at 1-day old and weekly till maturity. Interpretation PART II ADMINISTRATION 3. (1966). The experiment showed that effective reproductive isolation could be obtained through selection in very few generations. Animal Model Program used to predict the breeding value and real producing ability for animals depending on one trait and then these values were ranked in descending order for each sex to selection purposes. Rank correlation coefficients among breeding values as well among real producing abilities of studied traits were obtained. Lec 01 – Aims and objectives of Plant Breeding. Dedication: Henry A.

The cross (P 1 × P 4) in F 1 hybrids and in F 2 generation showed the highest mean performance for this trait. Lec 03 – Apomixis – classification and significance in plant breeding. Conception was monitored using a portable ultrasound machine. Similarly, the relative grain yield loss due to weed infestation was 41.8%. Genetics of Storage Protein in Maize. The cross (P 1 × P 4) in F 1 hybrid was the highest cross and the cross (P 2 × P 4) in F 2 generation was the highest crosses for this trait. Front Cover. Results indicated that the mean squares for earliness and yield and yield component traits due to parents, F 1 hybrids and F 2 populations were highly significant for all traits. The present investigation included six divergent cotton genotypes as parents. Resulted eggs from each family were collected during the peak of production for each generation to produce chicks of the next generations (G1 and G2). Optimum planting date has becomes a prime importance for higher crop production. When selection was for WT4W only, the genetic gain = 6.292 g. (2015). New plant genetic modification techniques, referred to as 'gene editing' or 'genome editing', have evolved rapidly in recent years, allowing much faster and more precise results than conventional plant-breeding techniques. The parents, their 15 F 1 hybrids and 15 F 2 populations were evaluated. Semen collection, evaluation and extension using the three diluents were carried out by standard methods. The integrated weed management (IWM) system is recommended to reduce the use of herbicides for its sustainable production. into cells and tissues using a particle bombardment process. 58, Karashanky, Giza 95 and (Giza 90 × Australian)). Two crosses out of hybrids, GZ 9461-4-2-3-1 / Milyang 349 and GZ 1368-S-5-4 / IR14K642 exhibited positive and highly significant SCA effects for grain yield plant-1, respectively. Body weights (BW): Genetic gain, correlated response, restricted selection index for body weights as well for egg traits and the correlation between the genetic merit and the index were computed. Thomas W. Whitaker. The predicted breeding values for each group (sires, dams, male and female chicks) depending on their BW at 10 weeks of age (marketing age) averaged 81.621, 100.797, 87.301 and 71.56 g and on BW at 17 weeks of age were 88.422, 109.197, 94.576 and 77.523 g respectively.

Results showed that the highest mean performance was found for the parent (P 2) for (B.W.). Biologists commonly wish to introduce a wide range of substances into living cells. The cross (P 1 × P 4) in F 1 hybrids and the cross (P 3 × P 6) in F 2 generation were the earliest cross for this trait. Extensive examples are discussed of such variation in culture subclones and in regenerated plants (somaclones). Hybrid and improved maize varieties are more nitrogen-responsive than local varieties of maize. Exper. In order to measure the impact of any technology and prioritize investments, we must assess the relevant resources, human capacity, clusters, networks and linkages, as well as the institutions performing technological research and development, and the rate of farmer adoption. 22. Res. Haccius, B. Inbred line: It is a relatively true-breeding strain resulting from at least 3 successive generations of controlled self-fertilization or back crossing. 4. Yij is the variety mean of the ith variety at the jth environment, µ1 is the ith variety mean over all environments, β1 is the regression coefficient that measures the response of the ith variety to varying environments, δij is the deviation from regression of the ith variety at the jth environment, and Ij is the environmental index. The values of heritability were estimated as 0.42, 0.61, 0.76, 0.71, 0.43, 0.51, and 0.70 and of repeatability were 0.29, 0.26, 0.22, 0.38, 0.41, 0.74, and 0.78 for BW at 1 day, 4, 8, 9, 10, 16 and 17 weeks, respectively. The model included the genetic group and generation for the traits before sexing and the effect of sex added to the model for the traits after sexing. An experiment was carried out in kharif 2018 to estimate standard heterosis for yield and its contributing traits using 55 hybrids developed through line x tester design were evaluated at three different locations at Navsari Agricultural University, Navsari (Gujarat) with commercial check ‘OH 102’. Pure line: A strain in which all individuals have descended by self-fertilization from a single homozygous individual. 1. BATS, Agency for Biosafety Research and Assessment of. Repeatability for body weights estimated. The analysis of variance uncovered that there were highly significant differences for all the studied traits except panicle weight among parents and parents vs. crosses. New Age International Pvt Limited, 1998 - 432 pages. components of variability III. Resulted eggs from each family were collected during the peak of production for each generation to produce chicks of the next generation (G1 and G2). The additive gene action was noticed for days to 50% flowering, plant height, flag leaf area, number of panicles plant-1, panicle length, panicle weight, panicle density index, spikelets fertility, 1000-grain weight, and grain yield plant-1. Hatched chicks considered as parents (G0), and distributed randomly into ten families. 58, Karashanky, Giza 95 and)Giza 90 × Australian(). Plant breeding started with sedentary agriculture and particularly the domestication of the first agricultural plants, a practice which is estimated to date back 9,000 to 11,000 years. Repeatability for all studied traits also estimated. Lupi, C. (1995). Stability parameters for comparing varieties. 58 a variety introduced from American). Plant breeding is dominated by commercial breeding com-panies which refinance their breeding activities through issuing licenses. An established breeding program with clear aims and reasonable resources will produce a new variety regularly, every couple of … The accuracy of the index calculated as the correlation coefficient between the breeding and the index values (rIA): Sustainable Weed Management in Maize (Zea mays L.)

Effect of weed species on drought tolerant rice genotypes at Sundarbazar Lamjung Nepal, Effects of planting time on growth, development and productivity of maize (Zea mays L.). A selection experiment to develop reproductive isolation intraspecifically was conducted with maize, Zea mays L. Two populations, a white flint and a yellow sweet maize having different recessive marker genes, were employed. We have found that these particles can penetrate cell walls and membranes and enter cells in a nonlethal manner. Plant breeding programs can be divided into two groups including classical and modern plant breeding. Rank correlation coefficients between breeding values of each pair of BW at different ages were all positive and highly significant. Scientic Books Publishers & Distributors, E-mail: info@agritechpublishing.com | info@siyapub.com, Website: www.siyapub.com | www.agritechpublishing.com. Singh, J., (1987). The cross (P 2 × P 5) in F 1 hybrids and the cross (P 1 × P 5) in F 2 populations showed the highest mean performance for this trait. F. A. Bliss, John W. S. Brown. The parent (P 3) was the highest parent for fiber length. In particular the phenomenon may be employed to enhance the exchange required in sexual hybrids for the introgression of desirable alien genes into a crop species. It may also be used to generate variants of a commercial cultivar in high frequency without hybridizing to other genotypes. Proper nitrogen applications as basal doses at planting stage, split doses at critical growth stages namely knee high, and flowering stages are necessary for higher grain yield. The effect of generation on BW of chicks at all ages and BWG at 1-4, 4-8 weeks was highly significant and (P. Twenty-one hybrids developed from crossing seven lines and three testers were assessed for the extent of combining ability effects, heterosis and genetic parameters for yield and related contributing traits. As all traits of a plant are controlled by genes located on chromosomes, conventional plant breeding can be considered as the manipulation of the combination of chromosomes.

Weeds crop association, critical period of crop-weed competition, methods of weeds control, herbicide tolerant maize cultivars and losses due to weeds and economics of weed control in maize are discussed in this, Weeds compete with rice for water, nutrients, space and light. 2. b = 4.1078 (EW) + 78.8389 (DEP) + 0.9594 (DEM) Protection of plant breeder's rights 7. 2019 Journal Citation Reports (Clarivate Analytics): 34/91 (Agronomy) 124/156 (Biotechnology & Applied Microbiology) 110/234 (Plant Sciences) The concept of particle bombardment has been put forward as a universal mechanism for transporting substances into any living cell. The data show that the number of days from planting to flowering was probably the main factor. declines if applied in an excess amount of nitrogen. Multiple lines and crosses. j. Multiple regression, generalized lattices, unreplicated experiments, multi-factor experiments, series of experiments can be analysed. Objectives of Plant Breeding : 1. This article summarizes various effects of planting dates on maize growth, development and yield parameters. Plant breeding project. Interaction effect between variety and weed population showed non-significant results for all growth and yield attributes. (1978). Stn., Beni-Suef Governorate, ARC, Egypt. Proper semen extension is essential for successful artificial insemination and increased livestock production thereby helping in bridging the imbalance between livestock production and the high demand for animal protein in the developing world. rIA = = 0.84 **. The most e. Predicted breeding values for sires, dams, and female chicks depending on EW averaged 1.116, 1.298, and 2.157 g; on DEP were 1.344, 1.561, and 2.242 %; and on DEM were 0.675, 0.828 and 1.050 g respectively. Germplasm. The courses in genetics include principles of genetics, gene regulation and genetic control of plant reproduction. Moreover, the highest mean performance was found for the parent (P 6) for Uniformity ratio. C. Y. Tsai. Results revealed that the parent (P 4) was the earliest parent for (F.F.N.). Pages 11-58. Sukhadhan-3) and two weed management practices (Weeded condition and non weeded condition) were studied in randomized complete block design (RCBD) with three replications. physiological and biochemical changes in plants, which affect plant growth and development and such changes may lead to a drastic reduction in yield. 3. Food and Agriculture. The character proved to be easily selected, and thus the realized heritability values were 45.0% and 47.2% respectively for the white flint and for the yellow sweet maize. All rights reserved. Herbicides are popular and widely used measures to control weeds in maize production systems, but several studies have shown their negative environmental consequences. Pages 59-102. Plant breeding is based on phenotyping, not only because of tradition, but because of essence. b. . Principles of Plant Genetics and Breeding, 2 nd Edition introduces both classical and molecular tools for plant breeding. Nitrogen affects various physiological and biochemical processes in plant cells that ultimately affect the growth and development of the plant. Hatched chicks considered as parents (G0), and distributed randomly in to ten families. These three different ways are mid-parent heterosis, better parent heterosis (heterobeltiosis) and standard heterosis. Join ResearchGate to find the people and research you need to help your work. In general, there are three main procedures to manipulate plant chromosome combination. Eight healthy multiparous non gravid West African Dwarf (WAD) ewes and two sexually matured rams intensively managed on grass, fed concentrate and water (ad libitum) were used in this study. At sexual maturity, each family contained one male and six females. The chicks of black group significantly excelled the white group in their BW at 1 day, 4, 8, 16 and 17 weeks, as well their gain at ages 1-4 and 10-16 weeks. Introduction to Plant Breeding Master Gardener Training. The output of different research works clearly indicated that weed infestation led 20-80% reduction in maize yield. The white flint became about 5 days earlier and the yellow sweet about 2 days later. Delayed planting dates affect traits namely anthesis silking interval, photosynthesis, physiological maturity and dry matter production due to reduction in cumulative interception of photosynthetically active radiation (PAR). In addition, the parent (P 4) was the earliest parent for (D.F.F.).

Plant breeding is time-consuming and costly. The modern method of plant breeding is carried out in the following steps:-Collection of Variability. These genotypes were crossed in a half-diallel genetic design according to Griffing's method II, model I (1956). Sharp, W. R., Sondah, M. R., Caldas, L. S., & Maraffa, S. B. It is argued that this variation already is proving to be of significance for plant improvement. Eberhart, S. A., & Russell, W. A. Late planting dates cause higher non-structural carbohydrate concentration in stems at mid-grain filling stages due to low temperature exposure of crop limiting kernel growth and photosynthesis. Phenotypes are harvested and consumed. Weed control measures should be taken during this period to minimize the yield loss of maize and increase the water and nutrient use efficiency. For practical breeding situations of self- and cross-fertilizing crops, analyses of variance, and entry means can be calculated. genetics, cytogenetics, plant breeding, quantitative genetics, molecular biology and biotechnology. 520 fertile eggs were taken from Agri. These genotypes are (Giza 85, Giza 91, C.B. b. d. Higher genetic (0.67) and phenotypic (0.49) correlations were recorded between EW and DEM, while the correlations between EW and DEP were negative and being -0.40 and -0.17 on the same order. The plots having highest number of weed population showed greater loss of rice yield. The relative heterosis will only help to understand the genetic status of the characters (Moll and Stuber, 1974) [30] . The two populations were planted mixed in the same field, and at harvest all intercrossed kernels could be readily detected since they expressed the two dominant genes. The highest grain yield (3.99 t ha-1) and straw yield (6.90 t ha-1) was found in weeded plots compared to non-weeded plots (2.321 t ha-1 and 6.43 t ha-1, respectively). The review shows that crop yield increases up to certain limit and, Weed species and maize crop strongly compete for nutrients, water, space and light for their growth and development. Crop varieties respond differently to planting dates. comment. Breeding values were obtained depending on chicks BW at 1 day, 4, 8, 9, 10, 16 and 17 weeks of age. The F 1 (P 4 × P 6) in hybrid was the best cross as well as the cross (P 1 × P 4) in F 2 generation for this trait. The estimates of the squared deviations from regression for many hybrids were near zero, whereas extremely large estimates were obtained for other hybrids. a. Six divergent cotton genotypes were used as parents in the present investigation. Thus this study suggests that weeding should be carried out to achieve higher rice production. Results cleared that the parent (P 3) was the best parent for micronaire reading. h. The rank correlation between estimated real producing ability also calculated and being 0.76, 0.62 and 0.82 (P≤0.01) between EW and each of DEP and DEM, and between the last two traits, respectively. The mechanisms involved in the isolations were investigated. Highly significant effects (P≤0.01) of genetic group and generation on EW were observed, the differences between the two lines and the generations in their DEP and DEM were not significant. Somaclonal variation- A novel source of. Estimates of repeatability obtained from this study were 0.29, 0.26, 0.22, 0.38, 0.41, and 0.74 for BWs of chickens at 1 day, 4, 8, 9, 10 and 16 weeks of age respectively (Table 9).
