Abstract
The study on physiological characterisation of cluster bean genotypes for growth and yield was carried out at COH Bengaluru. Where in, 75 genotypes including 3 checks were used for the study. The ANOVA for all the morpho physiological, biochemical, and yield traits studied revealed significant variations among the genotypes. The phenotypic coefficient of variation was higher than the genotypic coefficient of variation for all the characters studied. The phenotypic coefficient of variation ranged from 5.89 (Plant height) to 60.98 (Number of branches per plant). Genotypic coefficient of variation ranged from 3.20 (Test weight) to 60.53 (Number of branches per plant). The estimates of heritability ranged from 96.7 (Pod yield per plant) to 18.75 (Test weight). Genetic advance expressed as percentage over mean ranged from 166.0 (Epicuticular wax content) to 14.55 (Plant height). Correlation studies revealed highly significant and positive association of SPAD value (0.249), number of pods per plant (0.430), days to first flowering (0.245), total dry matter (0.248), leaf area (0.272), number of branches per plant (0.400) with pod yield per plant. Selection based on these traits can be effective for developing high yielding varieties. Among 75 genotypes, COHBCBC M15, COHBCBC 6S2, COHBCBC M5, COHBCBC 23, COHBCBC 19, COHBCBC 26, COHBCBC 25, COHBCBC M3, COHBCBC 35 and Pusa Navabahar performed better with respect to both drought related and yield traits. COHBCBC M15, COHBCBC 33 out performed than checks for quality parameters like tenderness and fibre content respectively. Hence these genotypes could be used in further breeding programme.
