摘　　要：为准确评价国内外主要饲用燕麦(Avena sative L.)品种在四川不同地区的稳定性和适应性及不同试点的代表性和区分能力,采用双标图和BLUP预测模型对12个燕麦参试品种对在2018年自行开展的5个区试点的产量数据进行联合分析。结果显示:‘太阳神’和‘魅力’具有较好的丰产性和稳产性,具有在四川省内大规模推广种植的潜力;品种‘苏特’在阿坝红原具有较高的产量,可以在生态类型相似的高海拔地区推广种植;洪雅县具有较好的代表性和区分力,是理想的试点环境,可推荐作为区试验以及品种推广示范的地点。本研究客观地评价了参试燕麦品种的适应性以及试验点的代表性和区分力,可以为四川地区饲用燕麦主栽品种选择及区试点选择提供理论依据。In order to accurately evaluate the stability and adaptability of major domestic and foreign forage oat varieties in different areas of Sichuan and the representativeness and differentiation ability of the different testing sites,the bipolt and BLUP prediction model were used to jointly analyze the yield data of 12 oat cultivars tested in five testing eco-geographical sites in 2018.The results showed that cultivar‘Sun God’and‘Charm’had a fecundity and stable yield with a high potential to be planted in a large scale in Sichuan Province.The cultivar‘shooter’achieved a high yield in Hong Yuan,Aba,and can be extensively planted in high altitude areas with similar ecological conditions.Hongya county of Meishan city has good representativeness and distinguishing power,and is an ideal place for testing trial and promotion showing of oat varieties.In this study,we objectively evaluated the adaptability of oat varieties and the representativeness and differentiation capability of the candidate sites,our results can provide a basis for the selection of the excellent oat varieties and/or testing sites for the production of high-quality oat forage in Sichuan Province.
