Path analysis for growth, quality, yield and yield components in yardlong bean (Vigna unguiculata (L.) Walp. ssp. sesquipedalis verdc

Abstract

The present investigation was conducted on yardlong bean to identify the characters which mainly contribute to the pod yield. Twenty four genotypes of yardlong bean were evaluated during kharif, 2017 and observations were recorded on growth, pod yield and quality parameters. Path analysis study revealed that number of primary branches per plant (1.2042 G) and days to 50 % flowering (1.0309 G) showed very high positive direct effect on pod yield per plant at genotypic level and number of nodes per plant (0.4670 G) and protein content (0.3143 G) showed high positive direct effect on pod yield per plant at genotypic level.
