本研究于1975～1977年在日本福山市中国农业试验场进行。供试验的不育系有麦地 A、399—A、马丁 A 和瑞德兰 A 等。研究粒用高粱的散粉时间和散粉后花粉飞散的距离。为了配制高纯度的高粱杂交种种子,作者将不育系同恢复系或保持系邻接栽培,在不育系开花末期,按一定时间间隔做除袋处理。结果表明,上午4点以前、中午12点以后除袋的 This study was conducted in China Agricultural Experimental Field in Fukuyama, Japan from 1975 to 1977. Male sterile lines tested for cornfield A, 399-A, Martin A and Redland A and so on. Study the grain sorghum powder loose time and scattered pollen flying distance. In order to prepare high-purity sorghum hybrid seeds, the male sterile line was used to restore the line or maintain the line adjacent cultivation, at the late flowering stage of the male sterile line, in addition to bag processing at certain time intervals. The results show that before 4 o’clock in the morning, after 12 o’clock in addition to the bag
