一、育种目标我省地处北纬31°21′-36°20′之间,小麦产区跨黄淮平原冬麦区和长江中下游麦区两大生态类型区.育种目标与邻近省份不尽相同,省内也有很大区别.大体说来,豫北(黄河以北)和陇海铁路沿线小麦生育期降水量多在200毫米以下,较正常需水量少1/3以上.春旱尤为严重,干热风也常发生,安阳地区还存在越冬冻害问题.干旱是丰产、稳产的主要限制因素,应把耐旱性作为育种中抗逆
I. Breeding Objectives The province is located between 31 ° 21’-36 ° 20’N and the wheat growing area crosses the Himalayan Plain and Himalayas and the middle and lower reaches of the Yangtze River. In general, the precipitation in wheat growing areas along the north of Yubei (north of the Yellow River) and Longhai railway line is more than 200 mm, which is 1/3 less than the normal water requirement, especially in spring , Hot and dry wind also often occur, there is winter frost damage Anyang area is the key factor for high yield and stable yield, drought resistance should be used as breeding resistance
