| 摘 要： | 以三系杂交组合新香优８０为对照，研究了大穗型亚种间杂交组合８１０Ｓ／６３００４的单株产量构成。结果表明，单株有效穗数不足是影响大穗型水稻产量的主要因子，单株有效穗构成也影响大穗型水稻产量形成。随分蘖级次升高，大穗型水稻单穗生产力下降明显。

| Abstract: | In this experiment,the yield composition of a single plant of the big panicle rice,cross combination 810S/63004,is studied.It is compared with the trilinear hybrid Xinxiangyou 80 in every respect throughout the experiment.Results show that insufficient number of ears is the most important factor that affects the yield of the big panicle rice and the composition of available ears also affects the yield of a single plant.The yield of a single plant of the big panicle rice decreases significantly with the rising of tillering grade. |
