杂交水稻稻瘟病抗性育种体系研究进展

Research Progress of the Blast Resistance Breeding System in Hybrid Rice

改良稻瘟病抗性是当前杂交水稻育种的主要目标之一。从稻瘟病生理小种的鉴定、水稻材料的接种鉴定、抗源筛选、抗性基因的分子检测及抗瘟性品种的选育等方面介绍了杂交水稻稻瘟病抗性育种研究进展。

The improvement of rice blast resistance is one of the important breeding objectives of hybrid rice. The research progress of blast resistance breeding of hybrid rice was introduced from such aspects as identifying of thephysiological races of Magnaporthe oryzae, identifying of the blast resistance of rice cultivars by inoculation, screen ing of resistant resources, molecular detecting of resistance genes and breeding of hybrid rice varieties with blast re sistance.
