Abstract:
A field experiment was conducted at All India Co-ordinated Research Project on Vegetable Crops, Department of Horticulture, Mahatma Phule Krishi Vidyapeeth, Rahuri, Dist. Ahmednagar (Maharashtra) during the Summer season in the year 2019. The present investigation was undertaken with 5 progenies with their 20 plants of each progeny for a cross RHR PK-10-1-1 x RHR PK-19-2-1-3 (C:3x4) of pumpkin in F4 generation for evaluating their genetic components such as variability, heritability, genetic advance, genetic advance as a per cent mean and correlation for growth, yield and yield attributes. Significant variations were found among the genotypes for most of the characters studied. The maximum phenotypic and genotypic coefficient of variation was observed for characters viz. number of primary branches per vine, number of fruits per vine, fruit yield per vine, fruit weight and fruit yield per hectare. high calculates of heritability were associated with high calculates of per cent mean of genetic advance were observed for the characters like per vine number of fruit, fruit length, fruit diameter, per vine fruit yield, per plot fruit yield, per hectare fruit yield, flesh thickness, number of ridges per fruit, seed cavity length, seed cavity width, number of seed, 100-seed weight and TSS. fruit yield per plant had highly significant positive association observed for final vine length, number of fruit per vine, weight of fruit and fruit flesh thickness.
