1 确保亲本纯度近年来,繁殖亲本的单位提供的亲本或多或少存在一些纯度问题。如1997年从四川引进的龙特浦 A 不育系杂株率在1%～2%,广西南宁地区的珍汕97A 不育系的杂株也在1%～2%。所以种子公司经营负责人及检验人员对用于制种的亲本种子调进要严格审查,检验合格后填写《种子质量合格证》,并由检验人员签章后方可使用于制种田。不乱调非省、地农科门私繁、滥繁,未经审批
1 to ensure the purity of parents In recent years, breeding parents of the units provided more or less purity of the parent. For example, the rate of heterosis of Longtepu A CMS introduced from Sichuan in 1997 was between 1% and 2%, and that of Zhenshan 97A in Guangxi Nanning was between 1% and 2%. Therefore, seed companies responsible for the operation and inspection personnel for the seed used for seed production transferred to a rigorous review, after passing the test, fill out the “seed quality certificate”, and signed by the inspectors before they can be used for farming.
