早熟糯稻组合产量及其构成性状的关联度分析

摘要

In this paper, the correlation analysis had been made for the key factors of early maturing glutinous rice. The result showed that the correlation degree in size was ranked: Effective panicle number> Grain num-ber per pan> Seed setting rate> Thousand-grain weight. Meanwhile, it can provide reference for screen high yield combination of hybrid glutinous rice in the early season.%对影响早熟杂交糯稻产量的几个关键影响因子进行了关联度分析，结果表明，在对产量起影响的诸多因素中，各因子对产量的影响程度为有效穗＞每穗粒数＞结实率＞千粒重，可为在早季筛选高产杂交糯稻组合提供借鉴作用。
