摘　　要： 西藏紫青稞富含紫色素等多种营养功能成分,其农艺性状与产量和品质密切相关。本研究以从西藏大麦产区收集的14份紫青稞农家种质资源为研究对象,对其农艺性状进行综合分析。结果表明:西藏紫青稞株高较高,分蘖力较强,千粒质量较大,穗密,不耐倒伏。各农艺性状因子对单株产量贡献大小依次为:主穗粒质量>单株有效穗数>分蘖穗粒数>主小穗数>第1节间长>第2节间长。 Purple highland barley grown in Tibet is rich in purple pigment as well as other nutritional and functional components, and its agronomic traits are closely related to its grain yield and quality. Fourteen landrace varieties of purple highland barley were collected from Tibet barley production areas; their agronomic traits were comprehensively evaluated in a field experiment that consisted of three replicates per landrace variety. As a result, these Tibet purple highland barley landraces had relatively great plant height, strong tillering ability, and large thousand-grain weight. Their agronomic traits contributed to their yield per plant in the following order from high to low： the mass of grains in the main panicle the number of effective panicles per plant the number of spikelets per panicle the number of main spikelets the length of the first internode the length of the second internode.
