Abstract:

The field experiment was conducted at Research cum Instructional Farm, College of Agriculture and Research Station, Singarbhat, Kanker, Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh) during Kharif 2013-14. The experiment was laid out in Randomized Block Complete Design with four replication, in-situ sixty genotypes of about 10 year age were selected for investigation, which were found as wild seedling plants on forest land and rice bunds. Investigation was carried out at Antagarh, Bhanupratappur, Charama, Durgkondal, Kanker, Koylibeda and Narharpur blocks of District- Kanker (Chhattisgarh). The treatments comprised of sixty genotypes with different character viz number of alternate leaf, length of leaf (cm), number of flowers per branches, days to 50 % maturity, total number of fruits, fruit width (cm), fruit length (cm), fruit weight (g), length of pedicel (cm), pedicel thickness, length of pericarp (cm), weight of pericarp (g), seed length (mm), seed width (mm), number of seeds per fruit, seed weight(g), pulp weight (g), areole weight(g), number of fruits per tree and fruit yield per plant (kg). Findings of analysis of variance revealed significant mean squares due to genotypes for all the traits under the study indicated the existence of sufficient genetic variability for the traits. The highest Genotypic and phenotypic coefficient of variation (GCV and PCV) estimates were observed for pulp weight, which is followed by areole weight (51.47% and 51.80) and fruit weight (44.70% and 45.10). The highest Genetic advance was observed for fruit weight (212.64) followed by pulp weight (122.27), areole weight (82.55). High heritability coupled with high genetic advance was found for was recorded for the character pulp weight, followed by areole weight, fruit weight and weight of pericarp. Rest of the traits exhibited medium to low genetic advance coupled with high to low heritability indicated the role of non-additive genetic variance in their expression.
