RELIABILITY OF YIELD CONTRIBUTING CHARACTERS FOR IMPROVING YIELD POTENTIAL IN CHILLI (Capsicum annum) (Pages : 30 - 38)

The experiment was conducted with 45 chilli (Capsicum annum) genotypes in the Field Laboratory, Dept. of Genetics and Plant Breeding, Hajee Mohammad Danesh Science and Technology University, Dinajpur during March to July, 2006 to study variability, association and direct and indirect effects present among themselves. Fourteen quantitative characters viz. days to 50% flowering, time between fruit set and maturity, plant height, primary branches per plant, number of secondary branches per plant, fruit length, fruit girth, fruit weight, number of fruits per plant, seeds per fruit, 100 seed weight, fruit pedicel length, vitamin-C content and dry fruit yield per plant were taken into consideration. The analysis of variance revealed remarkable variation among the genotypes for the characters concerned. The magnitudes of phenotypic coefficient of variations were higher than corresponding genotypic coefficients of variations. Higher genotypic as well as phenotypic coefficient of variations were computed for vitamin-C content, number of secondary branches per plant, number of primary branches per plant and yield per plant. Heritability estimates were higher for all the characters except days to 50% flowering and pedicel length. High heritability coupled with high genetic advances were estimated for seeds per fruits and plant height. Dry fruit yield per plant showed significant and positive correlation with number of secondary branches per plant, fruit girth, fruit weight, fruits per plant, seeds per fruit and 100-seed weight. Fruits per plant and fruit weight exerted highest positive direct effect both at genotypic and phenotypic levels. Download
