摘　　要：根据12个多棱饲料大麦品种（系）在合肥地区两年的品比资料，对产量结构和主要农艺性状进行了相关和通径分析。认为品种间产量的高低，取决于总数的多少，分蘖成穗率高是增加穗数的主要因素。在株高，穗长和生育期3个性状中，穗长是影响千粒重的主要因素。文中还就合肥地区多棱大麦育种的有关问题进行了探讨。Through correlation and path analysis of two years yield test from feeding multirowed barley in Hefei, lt is in dicated that the cultivars yield is deter mined mainly by the number of spikes. The high effective panical rate made most contribution to the number of spikes, Spike length is the major factor to 1000 kernel weigh among plant hight、growth duration and spike length.
