영문 초록

The experiment was conducted to get basic information for cotton breeding program through seven-variety diallel cross population. Significant variance analysis was observed in days to flowering, days to maturity, plant height, length of stem internode, bolls per plant, boll weight, seeds per boll, lint weight per boll, 100-seed weight, staple length, length of seed, width of seed and lint percentage. Based on the Vr-Wr graphical analysis, the characters, days to flowering, bolls per plant, seeds per boll, lint weight per boll, 100-seed weight, staple length, length of seed and width of seed were found to inherit incomplete dominance, and the characters of days to maturity, plant height, length of stem internode, boll weight and lint percentage were assumed to inherit over dominance. The component of genetic variance analysis for days to flowering, lint weight per boll, 100-seed weight, staple length, length of seed, width of seed and lint percentage showed that additive effects were higher than dominant effects. The narrow-sense heritability(h²ns) for days to flowering, bolls per plant, boll weight, seeds per boll, lint weight per boll, 100-seed weight, staple length and length of seed showed high values as more than 0.41. The estimate of broad-sense heritability(h²bs) value was higher than that of h²ns because of the low importance of dominance effects.
