| dc.description.abstract | One hundred twenty genotypes of French bean (Phaseolus vulgaris L.) were evaluated in augmented design for yield and yield related traits and observations were recorded on eight quantitative characters. Significant differences were observed among the germplasm lines for the characters plant height and green pod plant-1. High PCV and GCV was observed for plant height, green pod plant-1 and green pod weight plant-1. High heritability estimate coupled with high GAM were observed for plant height, days to 50 per cent flowering and green pods plant-1 implying that these traits were governed by additive gene action. Correlation studies indicated that green pod yield plant-1 had high significant and positive association with green pod cluster-1, green pod length, green pod width both at genotypic and phenotypic levels. Path coefficient analysis for green pod yield plant-1 revealed that green pod plant-1 had the highest direct effect followed by green pod width. Indirect contribution of component characters viz., green pods plant-1 and days to 50 per cent flowering on green pod yield plant-1 was high through branches plant-1 and green pods plant-1. Genotypes grouped into four clusters. Intra cluster genetic diversity was narrow, but was greater among clusters. The Genotypes from distinct clusters could be utilized in hybridization programme to get high yielding varieties. Potential determinate genotypes for green pod yield plant-1 viz., EC325080, ARKA ANOOP, EC37166, EC283179, IC18175 and indeterminate forms viz., IC14913, IC17916, IC37144, IC37581, EC39073 were identified based on green pod yield-1 and pattern of cluster through diversity analysis. | en_US |
