两系法利用水稻杂种优势的实验研究,安徽芜湖地区农科所已有资料报道。我场科研队从一九七二年开始培育“一系两用”的不育材料——珍龙选,选用具有紫色标记性状的紫色稻做恢复系,获得了两系配套。配制了适合闽北双早栽培的早熟杂交水稻新组合——紫优一号。两系法没有保持系,在生产上利用较为简便,与常规釉稻品种结合恢复系多,转育紫色恢复系比较容易,是发展杂交水稻的又一条途径。目前,我们正在继续稳定和繁殖不育系、转育多种恢复系。以配制不同组合类型供生产上试种。
Two-line method to use rice heterosis experimental study, Anhui Province, Wuhu Agricultural Institute has been reported. Our field research team started to cultivate the “one series of dual-purpose” sterile material - “Zhenlong selection” from 1972, and selected the purple rice with the purple marking trait as the restorer line to obtain the two-line matching. A new combination of early maturing hybrid rice suitable for double-early cultivation in northern Fujian was prepared. Two lines of law did not maintain the Department, the production is more simple to use, and conventional varieties of glaze rice to restore more lines, the transfer of purple restorer line is relatively easy, is another way to develop hybrid rice. At present, we are continuing to stabilize and propagate CMS lines and transfer multiple restorer lines. To formulate different combinations of types for production trials.
