The experiment was conducted during rabi season of 1997-98 with 30 genotype collected from different parts of our country. The performance study of 30 cultivar showed good range of variation for plant characters viz plant height no of braches no of leaves and plant spread. Fruit characteristics also observed to have significant differences. Longest fruit was observed in cultivar RHRC-16-5(14.15cm) while the fruit with maximum weight was recorded in Phule suryamukhi (71.3 g) Fruit yield estimated on hectare basis was maximum in genotype LCA-304(113.33q/ha, which was followed by PKM (102.60q/ha) and PCi(86.09q/ha respectively. Drymatter(%) was observed to be highest in AC-3(23.86%.Plant mortality was highest in genotype sel-1-1(16.65% ) while fruit damage by insect infestation was maximum (24.70%) in genotypeAc-3. Analysis of variance revealed significant differences among the cultivars for all the characters except no of pickings.PCV and GCV were high for plant height, no of flowers per plant, no of fruit per plant, fruit length, fruit weight and fruit yield .High heritability coupled with high genetic advance were observed to be high for days to 50%flowering ,no of flower s per plant , no of fruits per fruit per plant, days to first picking ,first yield. The character association studies revealed that the fruit yield per plot had highly significant positive correlation with fruit yield per plant (0.641), no of fruits per plant (0.585) and no of flowers per plant (0.632).Results indicated that the cultivars LCA-304 ,PKM and PC-1 were high yield cultivars for green chilli fruits,and the component characters like no of flowers per plant,no of fruits per plant and fruit weight per plant were found important in improvement of chilli cultivars.EnglishThesis
