Correlation study of floral traits, yield and nutritional parameters in dolichos bean (Lablab purpureus L.) genotypes under Allahabad agro climatic zone

Abstract

The present study was conducted to the estimation of correlation analysis for quantitative traits in Dolichos bean (Lablab purpureus L.) In the field of the department of Biological science, Sam Higginbottom University of Agriculture, Technology and Sciences, Allahabad during the crop season 2016-2017. The experiment was conducted in Randomized Block Design having thirty eight genotypes in three replications. Green pod yield per plant was significantly positive correlated with pod length, pod width, pod weight, seeds per pod, vine length, 100 seed weight, protein content, pod per inflorescence, while non-significant and positively correlated with carotenoids, moisture content, number of flower per inflorescence, chlorophyll ‘a’, total chlorophyll while non-significant and negative correlated with inflorescence length, days to 50% flowering, fiber content, days to first flowering, chlorophyll ‘b’, at genotypic and phenotypic level.
