Abstract:
The present investigation was carried out in the field of Horticultural Research and Instruction Farm under Vegetable Science department, IGKV (Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh) to identify potential cross combinations among twenty-four F₁ hybrids for genetic improvement in bitter gourd obtained by crossing of four testers with six lines and are evaluated in RBD design with three replications. The analysis of variance for experimental design revealed that the differences among the mean square due to treatments were found highly significant for all the traits. In case of mean performance of F₁ hybrids Pusa Ausadhi X Pusa Rasdar followed by Kashi Suman X Pusa Rasdar and Pusa Ausadhi X Katahi Karela revealed the best promising hybrid for fruit per plant and average fruit weight while regarding fruit diameter Pusa Ausadhi X Katahi Karela, followed by Pusa Ausadhi X Pusa Rasdar” and Pusa Ausadhi X WBG-1 showed highest magnitude. Regarding earliness, BG-2 X Pusa Rasdar was the first cross to give the first picking followed by BG-2 X WBG-1 in case of days to first harvest, while among all crosses earliest female flower appearance was observed for cross BG-2 X Pusa Rasdar followed by Pusa Ausadhi X Pusa Rasdar and BG-2 X Katahi Karela.
