Estimation of heritability and genetic advance in 24 genotypes of bread wheat (Triticum aestivum L.)

The present study was conducted to estimate heritability and genetic advance in 24 genotypes of wheat for 12 quantitative characters. The mean sum of square for all 12 characters is found to be significant and PCV of all characters is slightly higher than GCV which shows little influence of environment for expression of all characters. Highest estimate of GCV and PCV were observed for character awn length, plant height and grain yield/plant. Character biological yield/plant exhibited highest heritability further followed by characters 100 grains/weight and days to flowering. Character plant height, biological yield/plant and no. of spike/plant shows high genetic advance.
