Estimation of genetic variability and heritability (Broad sense) for yield and yield components in some Brassicajuncea genotypes

Broad sense heritability and genetic advance were estimated among ten mustard {brassicajuncea l.) genotypes for yield and yield contributing parameters in rcb design with three replications. broad sense (bs) heritability estimates were higher (above 60%) for days to flowering,plant height,days to maturity,branches/plant and number of pods/plant. moderate heritability values were observed for grain yield. the expected response to selection was higher (> 20%) for number of pods/plant and grain yield kg/ha and moderate values ranging from 10-20% for selection response was recorded for plant height. days to flowering,days to maturity and number of branches/plant showed lower values (< 10%) for expected response to selection. the genotypes 022860,j-38 and 022862 have shown better results for most of the traits and could be used in focused future breeding programmes.
