16个燕麦品种在甘肃陇中地区的适应性评价与筛选

Adaptability Evaluation and Screening of 16 Oat Varieties in Longzhong Area of Gansu

为筛选适宜甘肃陇中地区种植的饲用燕麦品种,采用田间随机区组试验,对16个燕麦品种的生长特性、产量性状、倒伏情况以及病害发生情况进行测定,并利用主成分分析法对差异显著的13个农艺性状进行综合分析。结果表明:在甘肃陇中地区,16个燕麦品种鲜草产量最高的是猛士1号,可达70000.00 kg/hm^(2),干草产量最高的是牧王,为23333.33 kg/hm^(2),种子产量范围为828.57~2428.57 kg/hm^(2)。主成分分析得出牧王在该地区生产适应性最好,魁北克、猛士1号的表现也很突出,锋利则不适合在本地种植;本地自育品种定燕2号综合得分排名12。综合抗倒伏性和抗病性,蓝鸟1号的抗逆性最强。

To select suitable forage oat(Avena sativa) varieties for cultivation in Longzhong area of Gansu province,the growth characteristics,yield traits,lodging and disease occurrence of 16 oat varieties were determined by random block experiment.Thirteen agronomic traits of oat varieties with significant differences were analyzed using principal component analysis.The results showed that in Longzhong area of Gansu,the highest fresh grass yield of 16 oat varieties was Mengshi No.1(up to 70000.00 kg/hm^(2)),and the highest hay yield was Muwang(23333.33 kg/hm^(2)),and the seed yield range was 828.57 to 2428.57 kg/hm^(2).The principal component analysis revealed that Muwang was the most adaptable in the region,while Kuibeike and Mengshi No.1 also had outstanding performance.However,Fengli was not suitable for local cultivation.The local self-bred variety Dingyan No.2 ranks 12 in the comprehensive score.Considering lodging resistance and disease resistance,Lanniao No.1 had the strongest stress resistance.
