“…While the Expected Genetic advance was low for all traits, this is probably due to the low narrow inheritance of those traits. This result agreed with [25,[29][30][31][32][33].…”

Seven genotypes of bread wheat (Triticum aestivum L.) were used (SK 95, Side14, Side 12, SK94, Giemiza 9, Giemiza 7, Al-Fayyad) and their 21 crosses from half diallel cross, and they were planted at the Agricultural Research and Experiment Station of the Faculty of Agriculture. Agriculture - University of Kirkuk, using a randomized complete block design with three replicates in order to study the combining ability and the components of phenotypic variation and genetic parameters for the components of grain yield, parents and their crosses differed significantly in all traits, and parent 2 excelled in performance and effect of the general combining ability in the desired direction. The cross 2×6 showed significant superiority in the average of the studied traits, and the effect of the special combing ability, indicating that the heterosis breeding method can be adopted, and selection in the later generations, while crosses 2×4 and 2×7 excelled in grain yield and some of its components, and the effect of the special combining ability was not significant, which can be selected for in the early generations. The dominance variance showed higher than the additive variance, which was reflected in the decrease in the values of heritability narrow sense, and the degree of dominance was higher than one, so the over dominance is that controls the trait.

Fifty genotypes of CIMMYT bread wheat were evaluated at Agricultural Research Farm, BHU, Varanasi during 2019-2020.The analysis of variance revealed significant differences among genotypes for all traits. High Phenotypic coefficient of variation was recorded compared to the genotypic coefficient of variation. However, high genotypic coefficients of variation were found particularly for: grain yield per plot (8.71), harvest index (9.22), test weight (8.9), normalized difference vegetative index (9.59) and chlorophyll content (9.79), suggesting that these traits are having ample genetic potential for selection amongst genotypes, in breeding programs. The highest broad sense heritability manifested for harvest index (91.61%); remaining traits showed moderate estimates of heritability. Low to moderate genetic advance as percent mean was estimated for all the traits studied. This suggests the existence of variability for agronomic traits in the studied wheat genotypes which, should be exploited during future breeding programmes. Fifty genotypes were divided into six non-overlapping distinct clusters using tocher's method based on Euclidean distances. Thirty-one genotypes were classified in the first cluster accounting 62% of total genotypes followed by 15 genotypes categorized in the second cluster. The remaining four clusters have one genotype each. Divergence and cluster mean show that, crossings between genotypes of clusters (II, III), and VI could lead to recovery of good transgressive segregants for maximum heterosis in wheat varietal improvement.

“…Sometimes, selection for these traits can be misleading. Similar results were reported for days to flowering (Saroj et al, 2022), days to maturity (Acharya et al, 2020), plant height (Yadav et al, 2021), primary branches per plant (Didal et al, 2021), secondary branches per plant (Farooq et al, 2017), umbels per plant (Patel et al, 2018), umbellates per umbel (Rajbhar et al, 2021), seeds per umbel (Verma et al, 2018), test weight (Choudhary et al, 2021), harvest index (Acharya et al, 2020) and total oil content (Desai et al, 2018).…”

Thirty-seven genotypes of coriander including six check varieties were analyzed for variability, correlation, path coefficients, and genetic divergence. Genotypes were grown in RBD with three replications and observations were recorded for 13 different quantitative traits. Secondary branches per plant and total oil content confirmed high values of GCV and PCV. Seeds per umbel, test weight, and total oil content exhibited high heritability along with high GA (% of mean). Both genotypically and phenotypically, seed yield per plant exhibited a positive and significant association with umbels per plant, umbellates per umbel, test weight, and harvest index. On seed yield per plant, umbels per plant reported the highest positive direct effect. Genetic diversity analysis grouped the 37 coriander genotypes into 6 different clusters with the maximum inter-cluster distance seen between clusters III and VI. Among the thirteen traits, test weight contributed largely to the total genetic divergence.
