Abstract:

A study was undertaken to estimate the heritability, genetic advance and coefficient of variation of yield and yield contributing traits in thirteen genotypes of wheat. The study was conducted in randomized block design (RBD) with three replications at Mountain Agriculture Research and Extension Station, Kargil (SKUAST-Kashmir) during kharif season of 2018. Significant genetic differences were observed for all the quantitative characters except flag leaf width, indicating considerable amount of variation among genotypes. The higher magnitude of phenotypic coefficient of variation (PCV) was recorded for harvest index. The high heritability was estimated for the characters like harvest index, days to 50% flowering, plant height, flag leaf length, spike length and number of grains per spike. High heritability coupled with high genetic advance as percent of means was recorded for harvest index, plant height, spike length and grains per spike that indicated predominance of additive gene action in the inheritance of these traits. However in most of the cases, high genetic advanced was not accompanied with high heritability. High estimate of heritability (H2) was seen for most of the traits and moderate genetic advance was observed for number of tillers per plant and number of grains per spike. Exercising of selection pressure on these characters will be fruitful in improvement of the crop for yield.
