摘　　要：以新春9号为母本,新春6号为父本进行杂交,杂交当代种子用80Gy 60Coγ射线辐照,经多代单穗选择,温室加代,培育成早熟、优质、高产小麦新品种新春30号。于2009年3月通过新疆农作物品种审定委员会审定并命名。该品种稳产高产、适应性广、抗病性强(锈病和白粉病)、抗倒伏性强、生长势好、早熟,属于优质中强筋类型,产量水平为5250～9000kg/hm2。新疆农业科学院核技术生物技术研究所多年来利用辐射诱变与杂交结合选育小麦新品种取得的成果表明,辐射诱变与杂交结合的育种技术是选育抗旱高产、优质高产小麦品种的有效方法。F1 hybrid seeds of Xinchun 9/xinchun 6 were treated by 80Gy ^60Co γ-rays irradiation,after many generations’ selection on single spike in progenies,Xinchun No.30 with early maturity,good quality and high yield was bred.Xinchun No.30 was officially registered by Xinjiang Crops Variety Examination and Approval Committee in March 2009.It was characterized by high and stable yield（5250 ～ 900kg/hm2）,wide adaptation area,good resistance to rust and powdery mildew,lodging resistance and medium to strong gluten quality.The results showed that hybridization combined with irradiation is a useful breeding approach to develop new varieties with drought resistance,good quality and high yield potential.
