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-09-4-6 x RHR PK-10-1-1 (C:2x3) of pumpkin in F4 generation for evaluating their genetic components such as variability, heritability, genetic advance, genetic advance as per cent of mean and correlation for growth, yield and yield attributes. Wide range of variability was observed for most of the characters. High values of GCV and PCV observed for number of primary branches per vine, number of fruits per vine, yield per vine, fruit weight and total yield tonnes per hectare. While, moderate value were observed for the node number at which the first female flower appeared, days until the first female flower appeared, fruit diameter and fruit length. For the remaining features, such like final vine length, days until the first fruit harvest, fruit diameter noted low value of genotypic and phenotypic co-efficients of variations. high calculates of heritability were associated with high calculates of per cent mean of genetic advance were observed for characters like vine length, number of primary branches per vine, number of fruit per vine, fruit length, fruit diameter, fruit yield per vine, fruit yield per plot, fruit yield per hectare, flesh thickness, number of ridges per fruit, seed cavity length, seed cavity width, number of seed, 100-seed weight and TSS. The significant and high positive correlation both at phenotypic and genotypic level were observed between fruit yield per plot and the yield contributing characters such as final vine length, number of primary branches per vine, number of fruit per vine, weight of fruit and fruit flesh thickness.
