Variability Parameters of Yield and Quality Attributes in Bitter Gourd (Momordica charantia L.)

The experiment of the present research work was conducted during summer season of 2018-19 and 2019-20 at Horticulture Research Farm-I, Department of Horticulture, School of Agricultural Sciences and Technology, Babasaheb Bhimrao Ambedkar University (A Central University), Vidya-Vihar, Rae Bareli Road, Lucknow (U.P.), India. The analysis of variance clearly reveals significant differences among the genotypes for all characters. The observations recorded on various characters showed that the estimates of phenotypic coefficient of variation (PCV) were higher than genotypic coefficient variation (GCV) for all characters. The high phenotypic as well as genotypic coefficient of variation were observed in marketable fruit yield per plant (39.36%) followed by average fruit weight (29.73%) and number of branches per plant (27.18%). High estimates of heritability were recorded for different characters viz., average fruit weight (98.6%) followed by total soluble solids (97.8%), total sugars (97.7%) and days to anthesis of first pistillate flowers (97.2%). The parameters which observed were found to be very high estimate value of genetic advance in per cent of mean of (60.14%) average fruit weight (60.14%) followed by titratable acidity (53.73%), number of branches per plant (53.47%), total soluble solids (52.81%) and marketable fruit yield per plant (47.87%).
