我司是安微省杂交稻“三系”提纯、繁殖和制种基地。1992年,我们按《改进籼型杂交稻“三系”亲本配套提纯操作规程》继续进行汕优63、协优64二套材料的提纯,繁殖珍汕97A、协青早A500亩,不育系平均纯度达99.8%,保持系和恢复系纯度达99.9%。在提高亲本纯度方面,我们的作法是:从亲本提纯基础工作做起,严把“五关”,实施“五个”改进。
Division I is the hybrid rice Anhui Province “three lines” purification, breeding and seed production base. In 1992, we proceeded with the purification of two sets of materials, namely Shanyou 63 and Xieyou 64, according to the “Procedures of Supporting Three-line Parental Purification of Indica Hybrid Rice”, breeding 97A of Zhenshan 97A, A500 of Xieqingzao, The average purity of 99.8%, maintain and restore the purity of 99.9%. In improving the purity of our parents, our approach is to start with the basic work of purifying the parents, to strictly control the “five thresholds” and implement the “five” improvements.
