Abstract:
An experiment was conducted to estimate the genetic variability, heritability and genetic advance for seven qualitative characters viz., ascorbic acid, oleoresin content, capsaicin content, total extractable colour, red carotenoids, yellow carotenoids and total caroteniods. The phenotypic coefficient of variation was higher than genotypic coefficient of variation for all characters. High magnitude of PCV and GCV were observed for ascorbic acid, oleoresin content, yellow carotenoids and total caroteniods indicating the existence of wide range of genetic variability for these traits. High heritability coupled with high genetic advance as % of mean was observed for ascorbic acid, oleoresin content, capsaicin content, red carotenoids, yellow carotenoids and total caroteniods indicating the predominance of additive gene action making the selection more effective.
