12个燕麦品种在黄土高原沟壑区生产性能及适应性
为筛选适宜黄土高原沟壑区种植的高产、抗倒伏、抗病性强的燕麦(Avena sativa)品种,以国内外引进的12个燕麦品种为试验材料,分析其产量相关性状、倒伏率和病害发生率,并利用灰色关联度分析和聚类分析法进行综合评价。结果表明:12个燕麦品种干草产量为10 800.00~15 233.33 kg·hm−2,平均干草产量13 298.61 kg·hm−2;种子产量为3 095.24~7 857.14 kg·hm−2,平均值5 407.14 kg·hm−2;其中,‘坝燕6号’的倒伏率较低,红叶病和锈病发病率最低,为抗倒伏兼抗病品种。灰色关联度分析结果表明:株高、干草产量、叶茎比在灰色关联评价系统中所占权重最高,是品种选择时的重要指标。采用聚类分析方法将12个燕麦品种划分为3个类群,第Ⅰ类群可作为饲草品种,第Ⅱ类群可作为籽粒型品种,第Ⅲ类群倒伏率及病情指数低,抗逆性好。综合灰色关联度和聚类分析方法,筛选出适宜黄土高原沟壑区种植的产量高、适应性好的饲草型燕麦品种‘加燕2号’,籽粒型燕麦品种‘坝燕6号’和‘美达’。
