Abstract:

These studies were conducted at Oilseeds Research Institute, AARI, Faisalabad during 2001-02. Eight lines alongwith two varieties of Brassica juncea L. were evaluated for plant height, number of primary branches per plant, number of siliquae per plant, 1000 seed weight and seed yield per plant through genotypic coefficient variability, broad sense heritability, genetic advance, correlations and path coefficient analysis. Siliquae per plant was found as strong trait for seed yield improvement because it had higher genotypic coefficient variability, broad sense heritability, genetic advance, highly significant positive correlation and maximum direct contribution for improving seed yield.
