小麦是新疆的主要粮食作物之一,近年来棉花、甜菜等经济作物种植面积迅速扩大,而小麦播种面积则相应减少。为保证小麦总产不减,则单位面积产量必须有一个较大幅度的提高。为尽快培育出适于新疆气候特点和土壤条件的优质、高产、稳产的小麦新品种以满足新疆小麦生产发展的需要,农七师农科所采用花药培养新技术育出了奎花2号冬小麦新品种。 1 育种目标的确定和亲本选择 1.1 育种目标的确定 北疆地区农业生态环境复杂,虽对小麦生长发育的有利条件较
Wheat is one of the main grain crops in Xinjiang. In recent years, the area planted with cash crops such as cotton and sugar beet has rapidly expanded, while the sown area of wheat has been correspondingly reduced. In order to ensure that the total output of wheat will not diminish, the yield per unit area must have a substantial increase. In order to cultivate high-quality, high-yield and stable wheat varieties suitable for climate characteristics and soil conditions in Xinjiang as soon as possible to meet the needs of wheat production and development in Xinjiang, Nongqiu Teachers College gave birth to the new technology of anther culture of Kuhuahua No. 2 winter wheat New varieties. 1 Determination of breeding objectives and selection of parents 1.1 Determination of breeding objectives Agricultural environment in northern Xinjiang is complex, although the favorable conditions for the growth and development of wheat than
