Title : Genotypic and Phenotypic Correlation Coefficient Studies in French bean (Phaseolus vulgaris L.)

Abstract :

Thirty-one French bean genotypes (Phaseolus vulgaris L.) including 22 genotypes obtained from NBPGR, New Delhi, six genoytpes collected from lower Pulne hills of Western Ghats and three released varieties viz., TKD 1, Arka Sukomal and Sonali were evaluated in Randomized Complete Block Design (RCBD) with three replications during 2020-2022 at Horticultural Research Station, Tamil Nadu Agricultural University, Thadiyankudisai, Tamil Nadu. Genotypic and phenotypic correlation studies for nine characters were assessed for association between different characters, direct and indirect effects of component traits on pod yield and other horticultural traits viz., days to first flowering, days to 50% flowering, pod length (cm), pod girth (cm), number of pods per plant, pod weight (g), yield per plant (g), yield per plot (kg), yield per hectare (t) of French bean. The results revealed that days to first flowering and days to 50% flowering had associated negatively and significantly with pod yield. The other traits viz., pod length, pod girth, number of pods per plant and pod weight showed positive and significant correlation with pod yield in French bean.
