冬小麦巴冬4号是巴州农科所1973年以新冬5号为母本、巴冬3号为父本杂交后,经连续多年单株选择而成,1985年巴音郭楞州作物品种审定委员会予以审定并定名,1987年种植面积为8.8万亩,占巴州冬麦面积50%.冬小麦巴冬4号的育成过程,实际上就是生态育种过程.这是因为,一个品种能否成为当地的主栽品种,主要取决于它对当地自然条件、耕作制度和栽培水平的适应能力.本文就冬小麦生态育种谈几点体会.一、根据当地生态条件,正确制定育种目标巴州位于北纬35°40′—43°35′,东经 80°42′—93°45′,海拔885.3—1247.5米,境内有两湖一山(博斯腾湖、罗布泊,阿尔金山),冬小麦主要分布在轮台、且末、若 Winter wheat is a winter wheat Badong Agricultural Science Institute in 1973 to Xin Dong 5 as the female parent, the third winter as a male parent hybrid, after many years of continuous selection of plants from 1985 Baying Guo Luan crop varieties Validation committee to be validated and named, 1987 planted area of ​​8.8 hectares, accounting for 50% of Bazhou winter wheat area. Winter wheat barton 4 bred process, in fact, is the ecological breeding process.This is because, a variety can become Local cultivars mainly depend on their adaptability to local natural conditions, cultivation system and cultivation level.This article on winter wheat ecological breeding talk about a few experiences.According to the local ecological conditions, the correct breeding objectives Bazhou located at latitude 35 ° 40’-43 ° 35 ’, longitude 80 ° 42’-93 ° 45’E and elevation 885.3-1247.5 meters. There are two lakes and one mountain (Bositeng Lake, Lop Nur and Altun Mountain) If
