在综合研究水稻优质、多抗、高产、高效的生理基础、生态条件和关键性状遗传特性的基础上,采用“多元杂交,混系结合,株型理想,优化选择”方法,选出了优质、多抗、高产、高效的理想稻新品种。其中沈农8718、沈稻7号通过国家审定熏沈稻4号、沈稻5号等通过辽宁省审定。新品种的产量超过对照品种。经检测熏7个品种的米质达到国家优质稻米一级或二级标准熏其余达到三级标准。新品种各性状组配合理熏抗病性、耐寒性、耐旱性较好。采用的优化育种方法熏实现了育种目标。
Based on comprehensive study on the physiological basis, ecological conditions and genetic characteristics of key traits in rice with high quality, multi-resistance, high yield and high efficiency, this paper selected the methods of “multiple hybridization, mixed combination, plant type ideal, optimized selection” Multi-resistant, high yield, high efficiency of the ideal new rice varieties. Among them, Shennong 8718 and Shenyao 7 passed the examination and approval of Liaoning Province through the national examination and approval of Shenyao 4 and Shenmiao 5. The new varieties of more than the control of varieties. After testing the smoked seven varieties of rice to achieve the national quality rice level one or two standard smoked the rest to achieve three standards. The new variety of traits with reasonable smoked disease resistance, cold tolerance, drought tolerance is better. Optimized breeding methods used to achieve the goal of breeding.
