摘要：Broad sense heritability and selection response were measured among fifteen rapeseed (Brassica. napus L. genotypes for seed yield and yield related traits during 2010-2011 at The University of Agricultural, Peshawar. The experiment was designed in Randomized Co mplete Block with three replications. Broad sense heritability estimates were higher (>60%) for primary branches plant -1 , pod length, seeds pod -1 and seed yield plant -1 . Moderate (30-60%) heritability val ues were observed for pods raceme -1 and 1000-seed weight. The expected response to selection was higher (≥20%) for seed yield plant -1 whereas, moderate values (10-20%) for selection response were recorded for primary branches plant -1 and seeds pod -1 . Pods raceme -1 , pod length and 1000 -seed weight sho wed lo wer values (≤10%) for expected response to selection. Higher broad sense heritability estimates and considerable genetic advance could be a valuable tool for breeders to select improved genotypes of Brassica napus for higher seed yield . The genotypes J-35, J-38 and J-40 presented better results for studied traits and hence could be used in future breeding schemes.
