摘要

灌浆率是影响北方大麦产量的一个重要特征。本研究旨在确定籽粒灌浆率的遗传特性及其与其他农艺性状的关系。对来自两个杂交组合的33个双单倍体系和亲本进行了3年的鉴定。子代籽粒灌浆率谱的分布近似正态分布。籽粒灌浆率的遗传率分别为89.6%和90.0%。灌浆速度快与有效灌浆期短、抽穗期长、产量高相关，但与成熟期无关。快速灌浆似乎提供了一种在不延长成熟时间的情况下提高粮食产量的方法。

INHERITANCE OF GRAIN FILL RATE IN BARLEY

Grain fill rate is an important characteristic influencing productivity of barley (Hordeum vulgare L.) in northern areas of production. This study was conducted to determine the inheritance of grain fill rate and its relationship to other agronomic traits. Thirty‐three doubled haploid lines and parents from two crosses were evaluated for three years at Palmer, Alaska. The distribution of lines for grain fill rate in the progenies was approximately normal. Heritability of grain fill rate was 89.6% in one cross and 90.0% in the other. Rapid grain fill rate was associated with shorter effective grain fill period, longer time to heading, and higher grain yield, but not with time to maturity. Rapid grain fill rate appears to provide a means of improving grain yield without increasing time to maturity.
