利用野生二粒小麦选育春小麦新品种龙春3号和龙春4号

New Spring Wheat Varieties Longchun No.3 and Longchun No.4 Derived from Wild Emmer Wheat

为促进优质、高产、多抗小麦品种的培育,本文详细介绍了龙春3号和龙春4号的品种来源、选育过程、植物学特性、农艺表现及基因型分析,并简述了其配套栽培技术。小麦品种龙春3号和龙春4号是黑龙江省农业科学院作物资源研究所利用野生二粒小麦与当地普通小麦材料远缘杂交育成的,具有高产、优质和抗旱性突出等特点,拓宽了我国北方雨养农业地区小麦品种改良的遗传基础。2015年通过黑龙江省农作物品种审定委员会审定,分别定名为龙春3号(审定编号:黑审麦2015001)和龙春4号(审定编号:黑审麦2015005)。

In this paper,the breeding process,botanical characteristics,agronomic performance,genotype analysis and cultivation techniques of Longchun No.3 and Longchun No.4 were introduced in detail,so as to provide reference for developing high-quality,high-yield and multi resistance wheat varieties.New spring wheat varieties Longchun No.3 and Longchun No.4 were developed from the cross of wild Emmer Wheat and local common wheat line with characteristics of high yield,good quality and outstanding drought resistance.The development of the new varieties broadened genetic basis of wheat in rain fed agricultural structure in northern China.They were approved by Heilongjiang Crops Variety Approval Committee in 2015,and named Longchun No.3(approval No.:Heishenmai 2015001)and Longchun No.4(approval No.:Heishenmai 2015005).
