Genotypic and Phenotypic Variability and Correlation Studies in Ridge Gourd (Luffa acutangula L. Ruxb.)

Abstract

The research was conducted AICRP on Vegetable crops, Department of Horticulture, MPKV, Rahuri, Dist. Ahmednagar (M.S.) in RBD along with two replications evaluated that summer-2022. In F3 progenies in Cross-III P6 x P8 (Saloni-5 x NRG-9) with two parents ridge gourd. In eighteen characters studied that variability and broad sense heritability (bs) with genetic advance over mean and correlation studied that, the high GCV and high PCV observed for the number of branches/vine, fruit yield/vine, fruit yield/plot and fruit yield/ha reported that highest variability indicated characters for further improvement and the highest broad sense heritability (bs) along with the highest genetic advance over mean were observed in number of branches/vine, number of nodes which first male flower appeared, number of picking, weight of fruit, number of fruits/vine, fruit yield/vine, fruit yield/plot and fruit yield/ha. The fruit yield (q/ha) in F3 generation at genotypical and phenotypical of fruit yield indicated that highly significant positively correlated with number of branches/vine, length of vine, number of pickings, days to last pickings, diameter of fruit except genotypic level, weight of fruits and number of fruits/vine, in these characters was governed by additively gene action, the least influences by the environment effects indicating that better chance for the improve through the selections.
