 ABSTRACT

A field experiment was conducted to study the genetic variability, heritablity, correlation and path analysis of 63 chilli genotypes with two replications at Kittur Rani Channamma College of Horticulture, Arabhavi which falls under Northern dry zone of Karnataka. Study revealed that, highly significant difference among the accessions for all the characters studied. Environmental influence was very less on expression of characters as it was evident by narrow gap between genotypic and phenotypic coefficients of variation. Genotypic and phenotypic coefficients of variation were moderate to high for all the characters studied except green and dry fruit weight. High heritability was observed for all characters, except 1000-seed weight and high genetic advance as per cent mean indicating that simple selection would be sufficient for these traits to bring genetic improvement. Fruit yield had positive and highly significant association with number of fruits per plant and fruit set percentage. Strong association of these traits revealed that selection based on these traits would ultimately improve the fruit yield and it is also suggested that hybridization of genotypes possessing combination of such characters is most useful for obtaining desirable high yielding segregants. Path-coefficient analysis revealed that fruit set percentage and fruit weight had the highest positive direct effect on fruit yield both at genotypic and phenotypic levels and most of the fruit related traits contributed to fruit yield mainly through fruit girth and fruit weight. Hence, it would be rewarding to lay stress on these characters in selection programmes for increasing yield.
