| 摘 要： | 对1995年全国籼型杂交中稻迟熟组区试结果进行通径分析，结果表明：增加有效穗和结实率，可提高产量，过多追求大穗会导致减产。其适宜的产量结构应该是：有效穗270万/ha，每穗总粒数150粒，结实率80％，千粒重27～28g。拟采用的育种路线是籼爪交或粳爪交。

| Abstract: | The results of path coefficient analysis were as follow: to increase the number of effective panicles andseed setting can improve the yield. The result of reducing yield was due to seek after large panicle extremey. Thesuitable structure of yield should be with 2. 7 million effective panicles per ha, 170 spikelets per panicle,seed set-ting rate of 80%, and 1000-grain weight of 27-28 g. |
