GENETIC VARIABILITY, HERITABILITY AND GENETIC ADVANCE FOR QUANTITATIVE AND QUALITATIVE TRAITS IN CHILLI (Capsicum annuum L.)
Journal Title: International Journal of Agriculture Sciences - Year 2017, Vol 9, Issue 14
Abstract
Thirty three chilli germplasm were evaluated in a randomized block design with two replication to estimate genetic variability, heritability and genetic advance of twelve quantitative and four qualitative traits. The overall values of GCV lower than the PCV for all the traits. High magnitude of PCV and GCV were recorded for carotene content and followed by red pod yield/plant, dry pod yield/plant and capsaicin. High values of GCV are an indication of high genetic variability among the germplasm. The heritability estimates in broad sense were found to be high for all the characters except number of secondary branches per plant, capsaicin, days to first flowering, pod girth and thousand seed weight. High heritability estimates indicated the presence of large number of fixable additive factors and hence these traits can be improved by selection. The traits like carotene content, red pod yield per plant, dry pod yield per plant and mean pod weight with high phenotypic coefficient of variation, genotypic coefficient of variation, heritability and genetic advance as percent of mean, indicating that these characters are under additive gene effects and more reliable for effective selection.
