The effect of low light intensity (LI) on the period from sprouting to earing was studied in 12 cultivars of the spring common wheat under controlled conditions. Differences between cultivars with respect to their responses to LI (RLIs) were found both for those that were photoperiod-sensitive and those that were almost photoperiod-neutral. Specifically, a prolonged photoperiod and a low LI differently increased the period from sprouting to earling in different cultivars. Genetic analysis of the RLI demonstrated, for the first time, that the weak response was incompletely dominant in F1. The results of genetic analysis agree with the hypothesis that the cultivars Pitic 62 and Novosibirskaya 22 differ in alleles of two loci controlling the RLI in wheat.
在可控条件下，对12个春性普通小麦品种进行了弱光强度（LI）对从发芽到抽穗期影响的研究。在光周期敏感型和几乎光周期中性型品种中，均发现了不同品种对弱光强度（RLIs）反应的差异。具体而言，延长的光周期和弱光强度对不同品种从发芽到抽穗期的影响各不相同。对RLI的遗传分析首次表明，弱反应在F1中为不完全显性。遗传分析结果与以下假设相符：Pitic 62和Novosibirskaya 22品种在控制小麦RLI的两个基因座的等位基因上存在差异。
