An experiment was carried out to determine the genetic variability parameters and character associations in thirty-two chilli genotypes. Based on mean performance, 11 genotypes were observed to be superior for marketable green fruit yield than the standard check varieties ‘Him Palam Mirch-2’ and DPCH-40-2. High to moderate estimates of PCV and GCV with high heritability coupled with high genetic advance were observed for marketable green fruits/plant, marketable green fruit yield/plant, total green fruits/plant and average green fruit weight. Marketable green fruit yield/plant had positive and significant association with average green fruit weight, marketable green fruits/plant, total green fruits/plant, percent marketable green fruits/plant, ascorbic acid and capsaicin content. In view of direct and indirect contribution of component traits, selection on the basis of total fruits/plant and average green fruit weight would be a paying preposition for evolving high yielding genotypes for marketable green fruit yield. The present findings could be useful in selecting superior genotypes to achieve genetic gain and yield advantage in chilli breeding programmes
