优异种质资源的发掘、研究与利用是水稻育种的重要基础。本文对66份全球水稻分子育种亲本材料的稻瘟病抗性、碾米及外观品质进行了系统的研究和评价。结果表明,66份水稻种质资源中有11份碾米品质和外观品质较优的抗稻瘟病种质材料,这些优质抗病材料对选育优质、抗稻瘟病新品种(组合)具有重要利用价值。
The discovery, research and utilization of excellent germplasm resources are important bases for rice breeding. This paper systematically studied and evaluated the resistance, rice milling and appearance quality of 66 rice blast resistant parental materials. The results showed that 11 of the 66 rice germplasm resources were resistant to blast disease germplasm with good milling quality and appearance quality. These high quality disease-resistant materials are of great use for breeding high-quality, new blast-resistant cultivars value.
