摘要
1999年以桥梁亲本龙育98-211(优质、丰产)为母本,以优异品系龙选9782(优质、抗病)为父本有性杂交,经过10a的株系选择、丰产鉴定、抗性筛选和品质检验等分析,选育了集高产、优质和抗病等于一体的水稻新种质-龙育05-158,这说明利用性状优良的核心后代种质为杂有效手段。为了选育寒地水稻具有突破性的新品种,必须加强稻种资源的引进与创新,做好配合力的鉴定工作;同时立足寒地稻作,加强耐寒性鉴定。
Longyu 05-158 was bred by Longyu 98-211 as female parent,which with high quality and high yield, and Longxuan 9782 as male parent, which with high quality and disease-resistant. The new rice germplasm Longyu 05-158 with high yield,high quality,disease resistance was bred after 10 years of strain selection,anti- sexual selection,identification and quality inspection. It demonstrated that using excellent core germplasm as hybrid parents, adopting effective methods, and cooperation of multi-disciplinary were effective methods. In or- der to breed a breakthrough new varieties rice, it must strengthen the introduction and innovation, do well in combining ability identification work; meanwhile, must enhance cold tolerance identification based on the cold rice.
