19份燕麦品种(系)在重庆地区的生产性能与饲用价值综合评价

Comprehensive evaluation about production performance and feed value of 19 oat varieties in Chongqing

研究旨在筛选适合重庆地区种植利用的饲用燕麦(Avena sativa)品种(系)。试验研究19份燕麦品种的生产性能、营养品质和抗病性,采用灰色关联度法进行综合评价。结果显示:青牧3号干草产量最高(1.26 kg/m~2),显著高于白燕3号等9份品种外的其他品种(P<0.05)。营养成分分析显示:粗蛋白含量变异幅度最大(27.23%),其中青引2号粗蛋白含量最高(21.87%),19份品种的粗蛋白平均值为13.52%。抗病性分析显示:高抗品种(HR)为泰克、大汉,抗病等级以上的品种共8份,未见锈病免疫品种。灰色关联度法综合评价筛选出表现较好的燕麦品种为坎燕4号、白燕3号、青牧3号。研究表明,坎燕4号、白燕3号、青牧3号适合在重庆地区推广种植利用。

The study was to screen forage oat(Avena sativa)varieties(lines)suitable for planting and utilization in Chongqing.The experiment studied the production performance,nutritional quality and disease resistance of 19 oat varieties,and used the grey correlation method for comprehensive evaluation.The results showed that Qingmu No.3 had the highest hay yield(1.26 kg/m~2),which was significantly higher than other varieties except Baiyan No.3 and other nine varieties(P<0.05).The nutrient composition analysis showed that the variation of crude protein content was the largest(27.23%),among which Qingyin 2 had the highest crude protein content(21.87%),and the average crude protein of19 varieties was 13.52%.Disease resistance analysis showed that high resistance varieties(HR)were Taike and Dahan,and eight varieties with disease resistance grade or above,and no rust immune varieties were found.The oat varieties with better performance were screened out by the comprehensive evaluation of grey relational degree method:Kanyan No.4,Baiyan No.3,Qingmu No.3.The study indicates that Kanyan 4,Baiyan 3 and Qingmu 3 are suitable for promotion and utilization in Chongqing area.
