Evaluation of Brassica Juncea Germplasm through heritability estimation and correlation analysis

Abstract

The experimental material was planted at the University of Agriculture, Peshawar to estimate genetic parameters of heritability and correlation for yield traits of indigenous Brassica Juncea genotypes. RCB design with three replications was used to sow 20 Brassica genotypes. Highly significant genetic variations were obtained among studied parameters. Days to half flowering revealed positive associations with primary branches per plant (r= 0.337^**). Primary branches per plant was positively correlated with pod length (r= 0.407^**), seed per pod (r= 0.418^**) seed yield per plant (r= 0.479^**). Similarly, pod length showed positive correlation with seed per pod (r= 0.324^*) and seed yield per plant (r= 0.331^**), while seed per pod was positively correlated with seed yield per plant (r= 0.878^**). Highest broad-sense heritability was recorded for seed yield per plant (0.97), while lowest heritability was estimated for primary branches per plant (0.46).
