掌握高粱光周期反应的遗传控制,在了解高粱基因型对各种气候区域的适应性时极为重要。Quinby等(1945)在首次证实作物光周期反应的规律性受特殊基因控制的一篇论文中指明,高粱的熟性遗传由4个基因位点控制。后来经选育,在迈罗和赫格瑞高粱的10种熟性基因型中,有效地组成了这些基因的各种组合。现已知道,大部分热带高粱栽培种的4个熟性基因位点全都是显性(Ma),而任一位
Mastering the genetic control of photoperiodic response in sorghum is extremely important in understanding the adaptability of sorghum genotypes to a variety of climatic regions. Quinby et al. (1945) indicated in a paper that first confirmed that the regularity of crop photoperiodic response is controlled by a particular gene, and the sorghum inheritance is controlled by four loci. Later bred, various combinations of these genes were efficiently made up in 10 mature genotypes of Miro and Hegre sorghum. It is now known that most of the four cultivars of tropical sorghum have all four dominant loci dominant (Ma), whereas either
