青稞(裸大麦)是西藏的第一大粮食作物,在西藏已经有几千年的种植历史。50年代后,在西藏开始进行了青稞的育种工作,经历了农家品种的大面积种植、对农家品种进行系统选育和杂交选育等过程。经过老前辈的努力和艰辛工作,目前,我区有70多个青稞品种,为西藏的农业发展和粮食生产做出了巨大贡献。但是,以往的青稞育种工作基于传统的选育方法,主要是对表型形状的利用和初步研究,即便做了大量的田间工作也很难选育出优良品种,效率极低。本文结合分子标记技术在近几年植物研究中的广泛应用,试图谈论西藏青稞育种的新思路和方法。
Barley (bare barley) is Tibet’s largest food crop and has been planted in Tibet for thousands of years. After the 1950s, the breeding of highland barley has started in Tibet. It has undergone a large-scale cultivation of peasant varieties, systematically breeding and breeding of peasant varieties. Through the efforts and arduous work of the predecessors, at present, there are more than 70 varieties of barley in our district, which have made tremendous contributions to the agricultural development and grain production in Tibet. However, based on the traditional methods of breeding, the previous research on the utilization of the barley is mainly about the utilization and preliminary study of the phenotypic shapes. It is very difficult to breed fine varieties even with a large amount of field work, resulting in extremely low efficiency. Based on the extensive application of molecular marker technology in plant research in recent years, this article attempts to discuss new ideas and methods of Tibetan barley breeding.
