西藏69份青稞地方品种种质资源的农艺性状

Preliminary Report on Agronomic Traits of 69 Highland Barley Germplasm Resources in Tibet

西藏青稞地方种质资源中蕴含了许多优异的基因,是青稞品种改良及新品种选育的重要遗传资源。本研究通过对69份青稞地方种质资源进行农艺性状分析,共筛选出8份特异种质资源,其中早熟材料2份、抽穗至成熟期时间较长材料2份、稀有籽粒颜色材料3份以及高杆材料1份。通过以上研究为我区青稞育种基因改良等相关工作筛选出一批宝贵的优异资源供其利用。

Local variety resources contain many excellent genes in Tibet,which is an important genetic resource for highland barley breeding and improvement.In this study,through the investigation and analysis of agronomic traits of 69 highland barley local germplasm resources,a total of 8 specific germplasm resources were screened,including 2 early maturing materials,2 materials with long heading to maturity,3 materials with rare grain color,and 1 high pole material.Through the above research,a batch of valuable and excellent resources were screened out for use in related work such as genetic improvement of barley breeding in our region.
