Twenty-three genotypes including check variety California Wonder were evaluated in polyhouse in Randomized Complete Block Design with three replications to estimate the extent of variability, heritability, genetic advance, correlation and path coefficient analysis for yield and other horticultural traits. Analysis of variance revealed significant differences among all the genotypes with respect to the characters studied. The genotype CAP-4 (10.86 kg) recorded highest marketable fruit yield per plot followed by CAP-1 (9.81 kg) and LC-1 (9.36 kg) which was higher than the check California Wonder (8.79 kg). CAP-1 was also found significantly superior over check California Wonder for other important horticultural traits viz., days to 50 % flowering, pedicel length, average fruit weight, fruit length, fruit width, harvest duration, total soluble solids and ascorbic acid. The estimates of PCV and GCV were high for average fruit weight. High heritability along with high genetic advance was observed for average fruit weight and fruit shape index. The correlation studies at genotypic and phenotypic levels revealed that marketable fruit yield per plot had significant and positive correlation with marketable fruit yield per plant, average fruit weight, fruit width, pedicel length, harvest duration, average seed weight per fruit, plant height, fruit length, plant spread, total soluble solids, pericarp thickness, ascorbic acid and lobes per fruit. The path coefficient analysis indicated that marketable fruit yield per plant had maximum positive direct effect on marketable fruit yield per plot followed by average fruit weight, plant height, pericarp thickness, harvest duration, marketable fruits per plant, days to first picking, fruit length and pedicel length. Therefore, main emphasis should be given on these traits, while making selection among capsicum genotypes.EnglishThesis
