稻瘟病是全世界水稻主栽区发生最严重的三大病害之一,据统计,平均每年因稻瘟病损失的产量可供6千万人食用。防治稻瘟病最经济、最安全的方法是培育含稻瘟病持久抗性基因的新品种。中垦锦绣华农武汉科技有限公司和湖北省农科院水稻研究所商业化育种的重大突破性品种——E两优476,通过构建双亲本抗稻瘟病的遗传群体,运用现代分子标记育种方法实现的含有双效抗性基因的双抗稻瘟病品种,解决了由于稻瘟病生理小种的高度变异性,
Rice blast is one of the three most serious diseases that occur in the rice-growing areas of the world. According to statistics, the annual output of rice blast loss due to blast can be consumed by 60 million people. The most economical and safest way to control rice blast is to breed new varieties with long-lasting resistance gene to rice blast. In Kenneth Jinhua Wuhan Science and Technology Co., Ltd. and Hubei Academy of Agricultural Sciences Institute of Rice commercialization of breeding a major breed - E Liangyou 476, through the construction of parents of the blast-resistant genetic groups, the use of modern molecular marker breeding methods to achieve Of double resistance blast resistant cultivars with double-effect resistance genes, which solves the problem that due to the high variability of physiological races of blast,
