Abstract:
Field experiment was conducted to evaluate twenty ridge gourd genotypes for growth and seed yield at Research and Development Station of Orbi Seeds International Private limited Sadahalli, during rabi-summer, 2022-23 and laboratory experiments on seed quality were conducted at Seed Technology Research Centre, AICRP on Seed (Crops) and Department of Seed Science and Technology, GKVK, University of Agricultural Sciences, Bangalore. The results indicated that, all the genotypes differed significantly for growth, seed yield and quality parameters. The genotype OSRG-007 recorded higher vine length at maturity (4.71 m), lower sex ratio (12.56), more number of fruits per vine (8.77), average fruit weight (889.28 g), fruit yield (39.84 t ha-1), number of seeds per fruit (152), seed yield per vine (205.73 g) and seed yield (10.35 q ha-1). Among the twenty genotypes, the genotype OSRG-016 recorded significantly higher seed quality parameters viz., seed germination, mean seedling length, mean seedling dry weight, seedling vigour index-I and II (94%, 38.47 cm, 100.95 mg, 3224, 9489 respectively) and lower electrical conductivity (100.4 μS/cm/g).
