 ABSTRACT

Chilli (Capsicum annuum L.) is one of the most important vegetable cum spice crop for small and marginal farmers in Asia, Africa and South America. Chilli is valued for its pungency which is due to crystalline acrid volatile alkaloid capsaicin, present in the placenta of fruits Experiment comprising 70 chilli accessions was conducted on genetic variability studies for twenty six quantitative and qualitative characters of Byadagi chilli. The phenotypic variances for all the twenty six studied characters were found to be higher than the genotypic variance. Very high GCV and PCV was observed for ascorbic acid content and high GCV and PCV was observed for average fruit weight, leaf area index at 45 Days after transplanting, fruit diameter, fruit length diameter ratio, number of fruits per plant, total dry fruit yield per hectare, early green fruit yield per plant, total green fruit yield per hectare, total green fruit yield per plant and dry red chilli yield per plant. Very high heritability coupled with very high GAM were observed for the characters fruit diameter, average fruit weight, number of fruits per plant, early green fruit yield per plant, total green fruit yield per plant, dry red chilli yield per plant, total green fruit yield per hectare, total dry fruit yield per hectare and ascorbic acid content. The study indicated that the additive component is predominant. Thus, there is ample scope for improving these characters through direct selection.

Key words: byadagi chilli, Fruit weight, Genetic advance, Genetic variability, Heritability.
