Abstract
The experimental material comprised of 12 promising genotypes of spine gourd (Momordica dioica Roxb.) were sown on 3 July 2018 at Horticulture Instructional Farm, COA, IGKV, Raipur (C.G). The experiment was laid out in Randomized Block Design with three replication.
Results of genetic variability indicated that sum of squares were highly significant due to genotypes for all traits.
Based on mean performance, genotypes like C.G Kankoda-2, RMD 15-2, NDMD 16-1, ASG 16-1 and ASG 18-1 were found higher yielder, early flowering and better growth along with other desirable characters.
Higher PCV and GCV was observed for fruit yield per plant (49.91%, 49.4%), no. of fruits per plant (29.34%, 28.54%), no. of branches per plant (35.98%, 32.72%), average fruit weight (20.64%, 20.43%) and 100 seed weight (22.89%, 20.99%).
High heritability along with high genetic advance was found for traits viz., fruit yield per plant (97.95%, 97.81%), hundred seed weight (84.11%, 39.67%), no. of fruits per plant (94.60%, 57.19%), average fruit weight (98.04%, 41.69%) and days to first female flower node (95.35%, 30.18%) which indicated predominance of additive gene action.
Correlation coefficient analysis revealed that fruit yield per plant shown a highest positive significant relationship with fruit length (0.461, 0.494), no. of fruits per plant (0.779, 0.800), no. of branches per plant (0.754, 0.825), fruit width (0.535, 0.602) and average fruit weight (0.365, 0.336) at both phenotypic and genotypic levels. Hence, in selection programme, emphasis should be given on these traits for improvement in fruit yield of spine gourd.
