摘 要：摘 要：该团队针对长江上游稻作生态特点及水稻生产中存在的问题，开展了绿色优质高产新品种的培育研究。先后发掘出与稻飞虱抗性、产量、品质性状相关的基因/QTL ；研发了稻米品质、稻瘟病抗性、稻飞虱抗性、磷高效利用、抗旱性、抗倒伏等绿色性状的改良技术；创制出兼具优质、高配合力、抗稻瘟病、抗飞虱等优良性状的新材料；培育出适合长江上游生态条件的绿色优质高产新品种并在生产上推广应用。
Abstract: Abstract: In view of the ecological characteristics of the upper reaches of the Yangtze River and the problems in rice production， large efforts have been made on the breeding of Green Rice with good grain quality and high yield in this study. As a result， several genes/QTLs related to rice brown planthopper resistance， yield and grain quality were identified. The technologies for improvement of grain quality， resistance to rice blast and brown planthopper， phosphorus-use efficiency， drought and lodging resistance were explored. A large number of new parental lines pyramiding the advantageous genes of good grain quality， high combining ability， improved resistance to rice blast and brown planthopper were developed. Even better， several new Green Rice with fine quality， high yield and good resistance to rice blast were bred， which are more suitable for the ecological conditions of the upper reaches of the Yangtze River and successfully applied in rice production.
