VIJAYAKUMAR SWAMY, H. V.SUNIL KUMAR, K.

The analysis of variance indicated the difference among genotypes were found to be significant except fallowing parameters days to 50% flowering, fruit girth, fruit length and mean internodal length. The PCV was higher than GCV for all characters. Higher GCV and PCV values were obtained for Primary branches per plant, Nodes per plant, Plant height and Fruit yield per plant indicating that variation of these characters contributed markedly to the total variability. High heritability coupled with high per cent of mean genetic advance was obtained for characters viz. Days to 50% flowering, Ridges per plant, Fruit girth, Fruit length, Fruit weight and Mean internodal length. Using D2 analysis of Mahalanodis (1936), thirty genotypes were grouped into eight clusters. Among the clusters, cluster I was the largest with fourteen genotypes followed by cluster VII and VIII with three genotypes respectively. Fruit yield per plant had strong and positive association with days to 50% flowering, Plant height and mean internodal length, both at phenotypic and genotypic level. The extent of genetic variability at molecular level in combination with eleven characters was assessed among okra genotypes along with magnitude association with fruit yield and its component characters. The dendrogram was generated based on STATISTICA for AFLP data resulted in 2 major clusters under which 4 minor clusters are obtained. Minor cluster 4 was the largest with 22 genotypes followed by minor cluster 1 and 3 with 3 genotypes each and minor cluster 2 has just one genotype. The minor cluster 1 and 2 contains IC series genotypes. And in minor cluster 3 and 4 with some local genotypes suggesting the similarity between local, KA, PB and DOV series genotypes. Highest 100% similarity was observed between IC43746 and IC43750. Most of the local varieties are grouped under minor cluster 4.ennullThesis
