为了研究大麦种子休眠的遗传，并找到如何在选择中处理这一特性，在具有不同种子休眠水平的斯堪的纳维亚大麦品系之间进行杂交。温室、田间和人工气候室试验结果表明：（1）种子休眠受多对隐性基因控制，不受细胞质因素的影响。(2)相同的基因通过不同的种子休眠参数表达。(3)种子休眠性与其它农艺性状间的关系不密切。（4）种子休眠性的遗传力很高，即使是早分离世代的单粒种子也是如此。(5)最大的选择反应，预计后期收获阶段结合早期记录阶段。

In order to investigate the inheritance of seed dormancy in barley and to find how this character can be handled in selection, crosses were made between Scandinavian lines of barley with different levels of seed dormancy. Results from glasshouse, field and phytotron experiments revealed: (1) Seed dormancy is governed by several recessive genes, and is not affected by cytoplasmic factors. (2) The same genes are expressed through different parameters of seed dormancy. (3) No close associations between seed dormancy and other agronomic characters have been found. (4) The heritability of seed dormancy is high, even for single seeds of early segregating generations. (5) Maximum selection response is expected for late harvest stages combined with early recording stages.
