陕西关中大麦新品种(系)的适应性比较

Comparative Study on the Adaptability of New Barley Varieties(Lines)in Guanzhong,Shaanxi Province

为探究陕西关中地区大麦新品种(系)的适应性以及为大麦育种提供参考依据,本研究运用灰色关联度分析法,对12份大麦品种(系)进行分析。结果表明:BDM0714-2-2-2品系的加权关联度最大,r=0.8980,最接近参照品种BDM1439-1,可认为其在陕西关中地区的综合性状较优,基本适宜在关中及相同生态区域种植。

This field study was carried out to select new barley varieties(lines)suitable for planting in Guanzhong area,Shaanxi Province.Using grey correlation analysis,we compared the adaptability of 12 barley varieties(lines)in Guanzhong area.The main results are as follows.The line BDM0714-2-2-2 had the highest weighted correlation degree(r=0.8980),being the closest to the control variety BDM1439-1,which was shown to have good agronomic traits and strong adaptability to the ecological conditions in Guanzhong area in many years.The results suggest that BDM0714-2-2-2 has better comprehensive characters in Guanzhong area than the other tested varieties(lines).Hence,the new barley line BDM0714-2-2-2 is suitable for planting in Guanzhong and other areas with similar ecological conditions.The current research provides a reference for barley breeding in the future.
