| 摘要: |
| 用两组亲本杂交的 F1杂种及其亲本,分析了亲子相关和性状相关.结果表明:①亲子相关 F1株高、容重与高亲呈极显著的正相关;F1籽粒赖氨酸含量、百克蛋白质中赖氮酸含量、抽穗期与低亲分别呈显著和极显著的正相关;F1籽拉蛋白质含量、沉淀值与中亲呈极显著的正相关.②性状相关蛋白质亩产量与籽拉亩产量呈高度显著的正相关,与籽粒蛋白质含量亦呈正相关,但相关不显著;籽粒亩产量与千粒重、容重呈高度显著的正相关,与籽粒蛋白质含量呈显著负相关;抽穗期与千拉重、容重呈极显著的负相关;株高与千拉重呈极显著的正相关;千拉重与容重呈极显著的正相关;籽粒蛋白质含量与籽粒赖氨酸含量、湿面筋含量、干面筋含量呈极显著的正相关,与百克蛋白质中赖氨酸含量极呈显著的负相关;籽粒赖氨酸含量与湿面筋含量、干面筋含量呈极显著的正相关,与容重呈极显著的负相关;湿面筋含量与干面筋含量呈高度显著的正相关. |

| Abstract: |
| Using 12 F1 hybrids derived from the diallel cross of two T-cytoplasmic A- lines and each of six R-lines as well as their parents,the correlation between pa- rents and offsprings and the simple correlation between characteristics were studied during 1983-1984,with the purpose of providing information for plant breeding practice. The results were as follows. (1)The positively significant correlation was found between the high-parents and offsprings in plant height and test wt.,between the low-parents and off... |
