Significant differences among the ABLs for all morphological and nutritional value traits were observed. High GCV and PCV values were recorded for all morphological traits among the ABLs and F1 hybrids. The component traits of drought tolerance viz., membrane stability index (MSI), relative water content (RWC) and chlorophyll content varied significantly among the ABLs. Based drought tolerance and nutritional values parameters COHB-14-1-8 x COHB-1-3-17, COHB-14-1-8 x COHB-6-1-15, COHB-6-1-15 x COHB-16-1-12, COHB-14-1-8 x COHB-16-1-12, COHB-14-1-8 x COHB-15-1-15, COHB-6-1-15 x COHB-14-1-8, COHB-1-3-17 x COHB-14-1-8 and COHB-7-1-15 x COHB-14-1-8 F1 hybrids were developed and evaluated: plant height (55.50-119.21), plant spread (46.83-91.72), number of primary branches (5.60-8.34), stem girth (1.61-2.03), specific leaf area (92.92-141.76), days to 1st flowering (43.84-55.73), days to 50 per cent flowering (51.02-61.85), days to 1st fruit maturity (67.18-77.93), fruit length (7.71-22.24), fruit diameter (4.16-9.54), fruit length and diameter ratio (1.49-2.31), average fruit weight (54.51-115.16), number of fruits per cluster (1.60-1.06), number fruits per plant (9.55-33.87) and fruit yield per plant (1.10-2.16) and heterosis recorded significant difference among the F1 hybrids. COHB-1-3-17 x COHB-14-1-8 and COHB-7-1-15 x COHB-14-1-8 were superior among the tested F1s and check, Arka Anand. Superior hybrids and ABLs could be utilized in multiple locations for their performance.EnglishThesis
