陸地綿 F₁의 量的形質에 있어서 組合能力과 形質의 相關關係 = Combining Ability and Correlation for Quantitative Characters of F₁ Hybrids in Upland Cotton, Gossypium Hirsutum L

다국어 초록 (Multilingual Abstract)

Combining ability and correlation coefficient for F₁population from 7×7 diallel cross in the upland cotton were estimated for sixteen quantitative characters i. e., days to flowering, days to maturity, plant height, stem diameter, length of stem internode, number of bolls per plant, boll weight, number of seeds per boll, seed and lint weight per boll, lint percentage per boll, lint weight per boll, 100-seed weight, staple length, length of seed, width of seed, lint percentage vs. seed and lint. Mean squares of general combining ability, specific combining ability and reciprocal combining ability were significant for all characters observed. Mean squares of general combining ability for days to flowering, days to maturity, plant height, number of bolls per plant, boll weight, number of seeds per boll, seed and lint weight per boll, lint percentage per boll, lint weight per boll, 100-seed weight, staple length, length of seed, width of seed, lint percentage vs. seed and lint were expressed as higher values than those of specific combining ability and reciprocal combining ability, but those for stem diameter and length of stem internode were lower. Variety DGA T-3 showed general combining ability effects positively high for plant height, stem diameter, length of stem internode, number of bolls per plant, boll weight, number of seeds per boll, seed and lint weight per boll, lint percentage per boll, lint weight per boll, 100-seed weight, staple length, length of seed and lint percentage vs. seed and lint, and Stoneville 2-B was expressed positively with the high general combining ability effect for staple length. In specific combining ability effect, hybrids in Stoneville 2-B×Sanchung. were exhibited positively as high for staple length, and higher specific combining ability effects for yield component were found positively in Chamen×Mokpo 7, Chamen ×Sanchung, DGA T-3×Stoneville 2-B, R-2×Stoneville 2-B, Mokpo 7×Stoneville 2-B, Stoneville 2-B×Sanchuing. In reciprocal effect, hybrids in DGA T-3×Red leaf, R-2×Sanchung, Mokpo 7×Stoneville 2-B and Mokpo 7×Sanchung were exhibited positively high for yield component. Heritability for days to maturity, length of stem internode, number of bolls per plant, boll weight, lint percentage per boll, lint weight per boll, staple length, length of seed, lint percentage vs. seed and lint showed high values as more than 80.19 in percentage, and boll weight was correlated positively with number of seeds per boll, seed and lint weight per boll, lint weight per boll, 100-seed weight and staple length.
