The investigation carried out with twenty four diverse genotypes for ten characters revealed high heritability coupled with high genetic advance as percentage of mean for seed yield per plant, umbels per plant, harvest index and seeds per umbellate indicating high additive gene effects and are least influenced by the environment. Hence, the selection based on these characters will be more effective and reliable for crop improvement. The principal component analysis revealed that three components possessed eigen value more than 1. The PC1, PC2 and PC3 contributed 24.03, 20.82 and 17.56 per cent of variability. Together, they accounted for 62.41 per cent of the variability of the genotypes.
