GENETIC DIVERGENCE IN SUNFLOWER

Abstract

Fifty four genotypes of sunflower were studied for their genetic divergence by D² analysis for a set of divergent characters nambely seed yield and five other metric traits. The genotypes were grouped into seven clusters. Based on the intercluster distance and cluster mean for various character. potential parent were identified from clusters VII, VI and V for hybridisation programme. Head diameter, seed yield and days to 50% flowering contributed more towards genetic divergence."
