摘　　要：应用灰色系统理论中关联度分析法对14个多棱大麦材料的8个相关因素与产量的关联度进行了计算分析。结果表明,关联度由大到小依次为:成熟前时间、小区穗数、抽穗前时间、千粒重、穗粒数、单株穗数、幼苗习性。在多棱大麦高产育种和高产栽培中,应在适当的穗粒数和千粒重基础上主攻单位面积的穗数,选育(选用)多穗大穗型品种,并兼顾其它有利生物学性状的选择。Correlativity between 8 characters and yield of 14 multi-row barley was analyzed by grey correlativity analysis （GCA）. The results indicated that the order of grey correlativity was day number before maturing〉spike per plot〉day number before heading〉plant height〉 1 000-kernel weight 〉number of kernel per spike〉number of spike per plant〉seeding habit. The number of spike per plant should be a main aim character in high yield breeding and production of multi-row barley, based on proper kernel per hectare and 1 000-kernel weight. Multi-spike and big-spike varieties should be bred while other good biological options should be emphasized.
