对已出版的全部大麦资源目录上6775份多棱皮大麦千粒重进行分关统计、整理分析。初步结果：①多棱皮大麦千粒重随育种方法改进而不断提高。②展现了目前我国选育的多技皮麦卡拉重大作的分布状况和拉重水平。③国内多技皮大麦大位资源缺乏，而保存的国外多植皮大麦大粒资源相对较多。④多棱皮大麦大粒资源的分布与目前千粒重高低分布区域基本吻合，主要在春大麦和裸大麦区。⑤多棱皮大麦大粒资源主要表现春性、稀稳。并对多技文大麦大粒种质在育种上的应用作了初步探讨。
6775 copies of the polygamous barley grain weight on the published list of all barley resources branch statistics, sorting analysis. Preliminary results: (1) The 1000-grain weight of polygamous barley increased with the improvement of breeding method. ② shows the current status of China’s breeding multi-technology wheat McKara major distribution and pulling weight level. ③ lack of resources for domestic multi-technology leather barley, and save more foreign grafted barley grain resources are relatively large. (4) The distribution of polygamous barley grains is consistent with the current distribution of 1000-grain height and low distribution, mainly in spring barley and naked barley. ⑤ polygamous barley grain resources mainly spring, thin and steady. The application of multi-technology barley germplasm in breeding was preliminarily discussed.
