春小麦早熟性遗传规律的初步研究

Preliminary studies on the genetic law of prematurity in spring wheat

用生物统计学方法，对春小麦早熟性的遗传规律进行了研究．结果表明，小麦早熟性是一个受多基因系统控制的数量性状，抽穗期遗传以加性效应为主，早熟期的选择，较晚世代将更有效．

We studied the genetic law of prematurity in spring wheat by using biostatistics method.The result showed that prematurity of spring wheat was the quantitative character that was controlled by multilocus gene.The additive effect play key role in senetic of heading date.The selection of prematurity will be more effective than the later generation.
