Evaluation of Elite Cluster Bean [Cyamopsis tetragonoloba (L.)Taub.] Genotypes for Vegetable and Gum Purpose in Northern Dry Zone of Karnataka

Abstract

The study was conducted on evaluation of elite cluster bean [ (L.)Taub.] genotypes for vegetable and gum Cyamopsis tetragonoloba purpose in the northern dry zone of Karnataka during season at College of Horticulture, Bagalkot, Karnataka with twelve genotypes rabi collected form difference sources. All genotypes showed significant difference for all the characters studied. The maximum per cent of germination was in CAZG-06-1 (94.44%), Pusa Navabahar (86.44 cm) was the tallest among the genotypes and Gujarat Local (7.44) recorded higher number of branches per plant. Rajendra Nagar Local and Jodhpur Local took least number of days (22.00 days each) for initiation of flowering. Highest pod yield (158.72 q/ha) was in CAZG-06-1 followed by IC-11704 . The dry pod yield per plant and seed yield was significantly higher in CAZG-06-1. CAZG-06-1 was also superior with respect to gum content (32.86%). The highest protein content was in Rajendra Nagar Local (38.33%). The least crude fibre content was in AVT-II-GR-4 (4.10%). Pod yield per hectare was highly significant and positively correlated with number of pods per cluster (0.933), 100 seed weight (0.792) and ten dry pod weight (0.679). Dry pod yield per plant was highly significant and positively correlated with guar gum content (0.583), number of dry pods per plant (0.830) and number of seeds per pod (0.605). Seed yield per plant was significant positive correlation with dry pod yield per plant (0.594), 100 seed weight (0.706), gum content (0.579) and number of branches per plant (0.621). All cluster bean genotypes were moderately susceptible to powdery mildew except PusaNavabahar and Rajendra Nagar Local which were susceptible to powdery mildew. Economics of different genotypes revealed that highest net profit from CAZG-06-1 genotype followed by IC-11704 and RGC-1047.
