Genetic Variability in Seed Traits Considering Some Genotypes of Wheat

To evaluate the superior genotype (s) with the authenticate selection procedure, twenty (20) various wheat genotypes were undertaken utilizing their qualitative seed attributes like morphology and biochemical action through studies on genetic variability. The statistical design CRD was followed to analyse those seed traits on collected seed from the farms. Considering the seed morphology, V14 (HD3218) genotype showed prominence effect though an inconsistent leaning was observed for biochemical activities considering diverse genotypes in addition to wide range of variable expression for all characters among genotypes. Coefficient of variation provided a relative measure on variance among different traits. GCV and PCV were found highest in thousand seed weight followed by seed volume, length-breadth ratio, seed breadth etc. In biochemical parameters, the GCV and PCV specified its maximum difference for certain characters like soluble protein, peroxidase etc. but the values were very near in other cases representing high heritability. Heritability played a vital role in deciding the aptness and approach for selection of the character. Water absorption potential at initiation and after 24 hours, thousand (1000) seed weight, seed volume, peroxidase activity of fresh seed had high heritability (broad sense) coupled with high genetic advance as percentage of mean specified the multitude of additive gene action. These characters could be upgraded through selection procedure and these were most significant characteristic of seed. Hence, the assortment built on these traits would be very active for wheat genotype grown under West Bengal condition.
