摘要
本文通过对西藏春小麦地方品种及主要育种材料,历年来育成推广的代表品种的多年试验资料和生产使用情况的总结,并结合对全区小麦生产发展历史和各主要农区气象资料的分析,明确提出了“在保持我区春小麦品种穗大粒多、丰产性好、抗逆性强等优点的前提下,重点选育比藏春6号等品种早熟10天左右的中熟品种”,以适应变化了的春小麦生产条件,并据此育成了一批有苗头的新品种.
This paper dealed with the summarization of the test data in performance of the local varielies, major parent materials and some representatively spreaded varieties of spring wheat bred and released over several decades and the analysis of the history of wheat production and the climate data of main agriregions in Tibet. Based on this, a new bleeding objective had been determined. The selection stress was placed on the maturing Period, e.g.mid-season varieties, they should be ripening earlier 7-14 days than Zhangchun 6 with the prerequisite to keep the traits of larger spike and more grains, high yield and stronger adverse resistance in original spring wheat bred in Tibet. Several hopeful varieties had been selected under the guide of the idea.
