| dc.description.abstract | The genetic parameters for 13 quantitative characters were estimated in 33 genotypes (germplasm) of okra in All India Co-ordinated Research Project on Vegetable Crops, Odisha University of Agriculture and Technology, Bhubaneswar at Horticulture Research Station, following Randomized Block Design with 3 replications during 2013 (July - October). The genotypes showed wide range of variation for eleven characters out of thirteen characters studied. Among the genotypes evaluated V24 (2013/OKHYB-5), V13 (2012/OKHYB-13), V9 (2012/OKHYB-1), V19 (2012/OKHYB-15) and V15 (2012/OKHYB-7) are identified as ideal genotypes to be grown in Bhubaneswar (Odisha condition). High estimates of genotypic co-efficient of variation, heritability (broad sense) and genetic advance together were observed for the characters number of disease infected plants, yield per plant, fruit weight, days to 50% flowering and duration of fruiting suggesting additive gene action for expression of these characters. So, selection based on these characters will be more effective in improvement of fruit yield of okra. Correlation studies among the traits indicated that there is a strong inherent association between fruit yield with number of fruits per plant, nodes per plant and plant height with nodes per plant, fruit length; nodes per plant with fruit length, number of fruits per plant; fruit length with fruit weight, duration of fruiting; first flowering node with days to first flowering, days to 50% flowering and days to first flowering with days to 50% flowering and days to first harvest; days to 50% flowering with days to first harvest both at phenotypic and genotypic level depicting that these are important correlated characters for fruit yield in okra. Path analysis study revealed that days to first flowering, duration of fruiting, fruit weight and nodes per plant have maximum direct positive effect on fruit yield. The genotypes are grouped into eight clusters using D2 statistics in which cluster III and VI were the most divergent ones and hybridization involving parents from these two clusters would be result oriented. Among the characters number of disease infected plants contributed maximum towards divergence followed by duration of fruiting and days to first harvest. | en_US |
