Variability, correlation and path analysis in F2 population of cross between hot pepper and bell pepper
Author(s): Imran Khan and O Sridevi
Abstract: The extent of genetic variability, heritability, genetic advance as percent of mean and correlation coefficients in respect of 12 quantitative characters in the population of cross between Byadgi chilli and bell pepper were studied. High phenotypic and genotypic coefficient of variations for number of fruits per plant (68.02 and 52.16) reported, followed by dry fruit yield per plant, fruit volume, number of primary branches, number of secondary branches, plant height and fruit surface area. High heritability and genetic advance as percent of mean was observed for fruit yield per plant, average fruit weight, pericarp weight per fruit, seed weight per fruit, which could be improved by simple selection. A significant positive correlation of economic traits like number of fruits per plant, fruit weight and fruit lengths with fruit yield per plant was recorded suggesting that selection for these characters could lead to improvement in yield. Path analysis revealed that number of fruits per plant had maximum direct effects on fruit yield followed by fruit length, fruit diameter and pericarp weight. Thus emphasis should be given on these characters to improve yield potential. The traits such as fruit yield per plant, number of fruits per plant, fruit weight are important yield contributing characters and deserve due weightage, while formulating selection strategies for improvement of chilli. As high genetic variability revealed in F2 population studied, this can be effectively utilized for improving yield and component traits.
