Abstract:
A field experiment was carried out to evaluate the variability, heritability and genetic advance in F4 segregating generation of bitter gourd (Momordica charantia L.) during late kharif season, 2018 at Department of Vegetable Science, College of Agriculture, Odisha University of Agriculture and Technology, Bhubaneswar, Odisha, India. Ten F4 segregants along with seven parents were evaluated by adopting RBD with three replications. The analysis of variance revealed significant differences among the segregants and parents for all the characters under study. The estimation of coefficient of error variations (CVe) ranged from 1.62% in days to 1st harvest to 12.04% in sex ratio (male:female). The PCV values were higher than the GCV values as expected. Relatively lower difference between GCV and PCV was recorded in characters like days to 1st female flower (7.73-7.30), fruit girth (14.24-13.60) and days to 1st male flower (8.51-7.86), thus less influenced by environmental factors. High heritability along with high GA as % of mean was noticed for characters like fruits vine-1 (91.36% and 49.11%), fruit girth (91.12% and 26.74%), seeds fruit-1 (89.85% and 38.21%), total green fruit yield (89.35% and 44.67%), sex ratio (88.10% and 63.38%), internodal length (87.82% and 46.83%), fruit length (87.42% and 46.43%), average fruit weight (81.16% and 34.35%) and vine length (78.16% and 26.44%) indicating that these traits are controlled by additive gene action. So, there is an ample scope for direct selection of these traits in bitter gourd.
