| 摘 要： | １７个粳稻代表性品种，经２年重复试验，结果表明：（１）分蘖力的遗传力及相对遗传进度均较高，且与分蘖速度和单株产量达极显著正相关，故可作为株形育种的一个重要指示性状。（２）对分蘖与单株产量等的相关及通径分析现有水稻品种，以选育分蘖早、快、多而角度较大为宜。

| Abstract: | The experiment was conducted for two years by using 17 japonicarice varieties to determine the genetic relationship between tiller number and yield.The result showed that the tillering capacity can be used as an important prediction index of plant type in rice breeding due to high heritability and relative genetic advance and correlation with tilering rate and yield per plant.Path analysis also revealed that a high─yielding variety of rice should possess early,fast growing,heavy and scattered tillers. |
