水稻化学杀雄配、制种的最大特点,是亲本选配较自由和能广泛利用品种资源优势,是水稻杂种优势利用的一条新途径。目前在生产上应用的水稻杀雄剂有“杀雄剂1号”和“杀雄剂2号”;推广的组合有“赣化2号”和“钢化青兰”、“青化辐桂”等;大田制种产量每公顷可达到1.5吨左右。今后的研究利用重点是:进一步完善“化杀”制种达到高产、优质、低成本的制种技术;在继续利用现有杀雄剂的同时,研制高效、无毒的新一代杀雄剂;组配杂种一、二代可以利用的强优势新组合迅速应用于水稻生产。
Rice chemical kill male match, the most important feature of seed production, the parental option is more free and can widely use varieties of resources, is a new way for the utilization of rice heterosis. Currently used in the production of rice killing maleicide “kill male and female agent No. 1” and “kill male agent No. 2”; promote the combination of “Jiangxi No. 2” and “temperate Qinglan”, “ Etc .; field seed production per hectare up to 1.5 tons. Future research and utilization of the key points are: to further improve the ”kill" seed production to high yield, high quality, low cost seed production technology; continue to use the existing killing agent at the same time, the development of efficient, non-toxic new generation of maleicide; Group with hybrids one or two can take advantage of the new strong combination of rapid application in rice production.
