利用生育期相近、产量和农艺性状有一定差异的 10个杂交水稻组合配制成 2 0个混系稻 ,对混植后的产量与性状的关系进行了分析。结果发现易受环境影响的性状混植后容易发生变化 ,而受环境影响比较小的性状混植后变化不明显。混植后导致产量互促主要是由于混植共生后有效穗数、成穗率和单株重等比参配组合有所提高所引起的
10 hybrid rice combinations with similar growth periods and different yield and agronomic characters were used to make 20 hybrid rice lines. The relationship between the yield and traits after the hybrid was analyzed. The results showed that the traits susceptible to environmental changes prone to change after planting, and less affected by environmental changes after the change is not obvious. The result of mixed production resulted in the increase of yield was mainly attributed to the increase of effective panicle number, percentage of mature spike and weight per plant
