| 摘 要： | 以黑龙江垦区2006年～2008年区域生产试验的64个水稻品种(系)为材料,分析了2个熟期3a试验的平均产量与产量构成因素的关系。结果表明:在高产育种中,不同熟期应有不同的选择标准。中熟组应选分蘖中等、大穗的品种,早熟组应选择结实率高、穗数型品种。2个熟期高产育种的共同点是都应选择结实率较高的水稻品种。

| Abstract: | The relationship between mean yields and yield components in regional and production trials in Heilongjiang from 2006 to 2008 was analyzed taking 64 rice cultivars as entries.The results showed that different selection standard should be considered according to different maturity groups in high-yield rice breeding.In medium-maturing group,the varieties with mediate tillering ability and large panicle should be bred,but in early maturing group,the varieties with high seed setting rate and multiple panicles should be selected. |
