水稻节水抗旱种质创新

Germplasm Innovation of Water-saving and Drought-resistance Rice

培育不同类型的节水抗旱种质104份;培育节水和抗旱性明显提高的新种质45个,节约水资源30%以上,所培育的新种质产量与同类型主栽品种相当,品质达到国家优质标准;培育同时具有节水抗旱、营养高效、抗病虫等性状中两个以上的新种质38份,其中同时具有节水抗旱和抗稻瘟病的材料13份,节水抗旱和抗褐飞虱的材料14份,节水抗旱和抗白叶枯病的材料9份,节水抗旱、抗褐飞虱和抗稻瘟病的材料2份;积极推进节水抗旱稻新品种沪旱3号、沪优2号、绿旱1号、井岗旱稻1号、旱优113、03优66等的应用和示范。

104 lines that was different types of water-saving and drought-resistant germplasm were cultivated. 45 new germplasm materials were bred, whose the ability of water saving and drought-resistance has been significantly improved, and their production were not reduced, which quality to meet national quality standards and saved water more than 30%.13 new germplasm lines with resistance to drought and rice blast resistance were cultivated; 14 restore lines with resistance to drought and brown planthopper resistance were bred; 9 restore lines of water-saving showed the resistance to rice blast,while 2 restore lines were confirmed with drought resistance, brown planthopper resistance and rice blast resistance.Moreover,we are actively promoting the application and demonstration of new water-saving and drought-resistant rice varieties.Such as Huhan No.3,Huyou No.2,Lvhan No.1, Jingganghandao No.1, Hanyou No.113,03 you No.66.
