四川及南亚水稻品种杂种一代农艺性状的分析
对四川及南亚2个水稻类群的10个代表品种的45个双列杂交F1组合（按Griffing方法 2设计）的主要农艺性状进行了相关及主成份分析,结果表明：1每穗总粒数、单株产量的F1优势较大,亲本对其F1的贡献也较大;单株穗数、每穗实粒数次之;株高、穗长、粒宽较小;2在12个农艺性状的66组相关系数中,正相关达显著水平以上的有17组,占25.8%,负相关达显著水平以上的有8组,占12.1%。与每穗实粒数相关的11个性状中,有8个相关系数达到显著以上水平,与单株穗数相关显著的4个性状全为负相关;3构成和影响这45个F1的主要因子是穗部因子、籽粒因子和产量因子,其贡献率分别为30.39%、32.24%和2...

| Notes | 51-1213/S Rice restorer line; Variety groups; Correlation coefficient; Principal component analysis In this study,main agronomic characters of 45 diallel cross F1combinations（ by Griffing method 2 design） of 10 representative varieties from Sichuan and South Asian rice groups were analyzed. The results showed that：（ i） Among the characters investigated,spikelets per panicle（ SP） and grain yield per plant（ GYP） of the F1 population had the best heterosis,and they also had the greatest parental contribution to their F1; The effective panicles per plant（ EPP） and filled spikelets per panicle（ FSP）,took the second place; Plant height（ PH）,panicle length（ PL）,and 1000-grain weight（ TGW） contributed the lest.（ ii） Out of 66 pairs of correlation coefficiency of the12 agronomic traits,17 had significantly positive correlation,accounting for 25. 8 % of the total; 8 pairs had significantly negative correlation,representing 12. 1 %. Interestingly,out of the 11 agronomic characters associated with filled spikelets per pani |
