Abstract:
A study has revealed significant differences in the analysis of variance for almost all the traits. The traits exhibited in Table 2 were closely related to the mean sum of squares due to genotypes, with high significance for Days to 50% flowering, Days until maturity, Plant height, Flag leaf length, Productive tillers/M2, Peduncle length and Spike length. CG-1029 had the longest length of 37.67 cm, while a single genotype containing only 30.07 cm had as little fur as GC- The genotype CG-1029 had the highest recorded spike weight, which was 51.67 g. MP 3336 (7.35 cm) was the shortest spike length, while the average length of a peduncle was 34.58 cm. CG-2013 had the highest spike value (42.27) among the variations in grain density found in this study as well. The test weight of genotype CG-1029 was the highest (51.67 g) The traits Grains/Spike, Spike weight, No. of Spicelet's/SPike (cm), Flag leaf length (kilogram), and Test Weight (g) are the two highest values of PCV (14.66) and GCV (13.34) among all other recorded traits. Heritability was highest in Days to 50% flowering (95.55), followed by plant height (90.54) (cm), test weight (83.79) (g), Days until maturity (79.74), and Spike Length. The highest level of genetic progress was demonstrated by the traitof biological yield/plant (85.63) and grain production/plot. A positive and significant relationship exists between the yield of seeds and their attributes in correlation coefficient analysis for all major yield contributing traits. The results indicate a significant amount of variation among genotypes, which can aid in selecting the appropriate parent for future use in an imprudent wheat yield program. This is important.
