19781995年,以17个早、中籼良种为材料,先后进行了32个高产栽培试验,利用每个试验中较高产处理的产量及穗粒结构资料,研究了高产条件下籼稻良种产量组分,结果表明:①籼稻高产育种侧重提高有效穗数和千粒重;②大穗不是高产的主要指标,因为品种高产最适有效穗数与着粒数呈极显著负相关,即穗子较小的品种可以通过栽培措施增加有效穗数而获得高产;③千粒重稳定性较好,品种间千粒重差异极显著;④结实率受环境条件的影响较大,品种间差异不显著。
In 1978,1995, 17 high and middle indica varieties were used as materials, and 32 high-yielding cultivation experiments were carried out successively. Based on the data of yield and grain-ear structure of the higher yield treatments in each experiment, the yield components, The results showed that: (1) High-yielding indica rice increased the effective panicle number and 1000-grain weight; (2) Large panicle was not the main index of high yield, because the most effective and effective panicle number of high yield was extremely significant negative correlation Cultivation measures to increase the effective panicles to obtain high yield; ③ 1000 grain weight stability is good, the grain weight difference between the significant differences; ④ seed setting rate is greatly affected by environmental conditions, the difference was not significant between cultivars.
