Book excerpt: Heat stress sets an upper limit to maximizing wheat yields in many irrigated, low-altitude, tropical environments. Terminal heat stress also reduces wheat yields in certain Mediterranean environments in West Asia and North Africa. A study was carried out at three different environments in Sudan and Syria to identify potential selection traits and environments for breeding purposes. Seventeen morphological, physiological, and phenological traits were used to evaluate 16 diverse bread wheat genotypes under early, terminal, and continuous heat stress conditions. A plastic house experiment was also conducted to characterize the 16 genotypes for their response to photoperiod and vernalization. Early flowering/maturity, longer peduncles, larger number of kernels/spike, larger harvest index, and larger biomass played an important role under early and terminal heat stress conditions in Northern Syria. Medium flowering/maturity, semi-dwarf stature, denser ground cover, and larger biomass conferred better agronomic performance under continuous heat stress conditions in Wad Medani, Sudan. Unlike grain and biological yields, days to f lag leaf emergence, anthesis, and maturity showed stability across the three environments. Harvest index showed some stability across environments as well. None of the 16 genotypes was sensitive to day length. The late-maturing genotypes were sensitive to vernalization. A large amount of genetic variability was found for all the traits tested in all three environments to guarantee their use in a breeding program for heat stress.

This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present investigation was undertaken with the objective to evaluate the nature and magnitude of genetic variability and correlation of different spike traits and other character association with grain yield. Eighteen diverse bread wheat (Triticum aestivum L.em Thell.) genotypes and 72 F1 lines were evaluated to estimate the extent of association with respect to spike traits and grain yield. The coefficient for genotypic correlation for most of the character combination was higher in magnitude, as compared to corresponding phenotypic correlation coefficient, indicating largely the strong inherent nature of traits recorded in the present investigation. The yield per plant exhibited positive and strong association with all the traits except with 100 grain weight. From the present investigation, it could be suggested that breeder has to work cautiously for any breeding program aimed at improving particularly the 100 grain weight.

This book was released on 2011-01 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bread wheat (Triticum aestivum L. em. Thell) is one of the most important cereal grain crop of the world and is cultivated over a wide range of climatic conditions. For a successful breeding program the inheritance of yield related traits is a pre- requisite. This monograph communicates the inheritance pattern of yield and related traits in bread wheat (Triticum aestivum L.) using 8x8 diallel analyses. Graphical analysis revealed additive gene action for days to heading, days to maturity, plant height, grains per spike, 1000 grains weight and harvest index. While over dominance gene action for flag leaf area, tillers per plant, Spike length and yield per plant. The GCA mean squares were significant for all traits except tiller per plant and yield per plant and were greater than SCA mean squares indicating the preponderance of additive genetic effects. The parents Tkb, Tat, Sarc-3 and SQ- 92 were good general combiners. The parents Tkb , Tat , Sarc-3 and SQ-92 and the specific crosses that showed high mid parent and better parent heterosis are recommended for further use in wheat breeding programmes.

This book was released on 1983 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visual selection for grain yield may be a limiting factor in identifying superior yielding genotypes in a breeding program. This investigation was conducted (1) to compare the effectiveness of visual selection for grain yield by three selector groups representing different levels of plant breeding experience, and (2) to examine the association of selected traits with the process of evaluating plots visually for grain yield. The germplasm evaluated consisted of fifty non-segregating, diverse genotypes selected to include a wide range of expression for phenotypic characters. They were grown in solid-seeded, two-row plots with three replications in a randomized block design during 1981-1982. Data were collected on a plot basis for grain yield and twenty-two agronomic traits. Eighteen selectors were placed in three groups comprised of two plant breeders, eight graduate students, and eight summer student workers, respectively, from the Oregon State University cereal breeding program. Evaluations were made on two separate days by scoring each of the 150 plots on a scale of 1 to 5 for grain yield. The plant breeder selectors were the most successful of the three groups in discriminating both high and low yielding plots. The two best graduate student selectors were similar in ability to the plant breeders in scoring plots for high yield, although not in scoring for low yield. The remaining graduate student and summer worker selectors were generally not able to score more low and high yielding plots "correctly" than would be expected if selection were done at random. Considered individually, the most effective selectors failed to select several high yielding plots. However, when selections of the four most effective selectors were combined, only one of the twenty highest yielding plots was omitted. Results comparing trait association with actual plot grain yield and with selector scoring for plot grain yield suggested "biases" for or against certain traits. Biases for later heading and maturing plant types with wide flag leaves were common to all selector groups when visually selecting for high yield, as were earlier heading and maturing entries with narrower flag leaves when selecting for low yield. The plant breeder selectors were notable for lack of trait biases relative to other selector groups. In contrast, the summer worker selectors tended to overemphasize several spike characteristics whether selecting for high or low yield. Results suggested several other trait biases of individual selectors and selector groups.
