Analysis of variance for various quantitative characters revealed that the mean sum of squares due to genotypes showed high significant difference for all characters under study at 1% level and 5% level of significance. Scattered diagram revealed that 20 genotypes were grouped in to 5 complexes and maximum number of genotypes 11 was found in complex-1. High index score observed was 33 for a genotype SHIVA-555.
