野生稻优良基因的发掘利用研究进展

摘要

Wild rice contains various resistance genes which can resist biotic and abiotic stress,wild rice is also a genetic germplasm resource library for rice breeding.The excavation and location of wild rice elite gene were summarized in this paper,these genes＇ function including disease and insect resistance,abiotic stress tolerance,high yield.Finally,the elite gene utilization prospect in wild rice is forecasted.%野生稻中蕴含着大量抗生物胁迫和耐非生物胁迫的基因,是栽培稻品种进一步改良的天然遗传种质资源库。对野生稻中抗虫、抗病、抗逆、高产等优良基因的发掘及定位作了概述,并对野生稻优异基因的利用前景进行了展望。
