ASSESSMENT OF GREEN POD YIELD AND YIELD ASSOCIATED TRAITS IN WINGED BEAN GENOTYPES UNDER AMBIKAPUR CONDITIONS DURING KHARIF SEASON

Abstract

Winged bean (Psophocarpus tetragonolobus (L.) DC.) is an underutilized multipurpose legume with considerable potential as a vegetable and protein-rich crop. A field investigation was conducted during Kharif 2025 at Zonal Agricultural Research Station Ambikapur, Chhattisgarh, to evaluate nine genotypes for green pod yield and associated traits using a randomized block design with three replications. Among the tested entries, genotype RMDWB 23-1 exhibited superior performance, recording the highest green pod yield (171.01 q ha⁻¹), along with 282.17 pods plant⁻¹, 15.08 cm pod length, 16.20 seeds pod⁻¹, and 35.96 q ha⁻¹ seed yield. Correlation analysis revealed significant associations between total green pod yield and key yield components, including first-picking yield (r = 0.770), seed weight (r = 0.667), seed yield (r = 0.710), and pods plant⁻¹ (r = 0.654), with the strongest correlation observed for total yield (r = 0.973). Based on numerical performance and trait associations, RMDWB 23-1 emerged as the most promising genotype and warrants further evaluation for potential release and wider cultivation.
