摘要： 为了给西藏地区春青稞品种的选育与栽培管理工作提供一定的参考依据，笔者通过应用灰色关联度分析方法，计算了西藏地区13个春青稞品种8个农艺性状与产量性状的关联度。结果表明，单位面积成穗数、穗粒数、千粒重、株高、穗长、小穗数、退化小穗数以及生育期与单位面积产量的关联度分别为0.6334、0.6957、0.6394、0.7088、0.6955、0.7308、0.6241、0.6514；按关联度大小排序为小穗数>株高>穗粒数>穗长>生育期>千粒重>穗数>退化小穗数。从结果来看，培育大穗与秸秆较高品种，提高单穗小穗数、穗粒数可能成为今后西藏地区春青稞育种与栽培管理工作的主攻方向。

Abstract: Based on the application of the gray correlative analysis, the gray correlative degree between eight agronomy properties and yield of thirteen spring barley varieties in Tibet are calculated, in order to give a definite support to variety breeding and cultivation management of spring barley. It shows that the gray correlative degree between spike number per hm2 and yield per hm2 of spring barley is 0.6334, and respectively, grain number per spike 0.6957, and weight per 1000 grains 0.6394, and plant height 0.7088, and spike length 0.6955, and spikelet number per spike 0.7308, and invalid spikelet number per spike 0.6241, and growth period 0.6514. As a result, breeding and cultivation of spring barley varieties with bigger spike and higher stalk, and with increased spikelet and grain number per spike, probably will be the main task for us in the future.
