Comprehensive evaluation of the production performance of 7 oat varieties in the Northwest Plateau of Sichuan
In order to screen high-quality oat(Avena sativa L.)varieties suitable for planting in the Northwest Plateau of Sichuan,the growth period,yield traits,agronomic traits and nutritional quality of seven oat varieties at home and abroad were investigated,analyzed and compared for two years,and the grey correlation method was used for comprehensive evaluation.The results showed that all the seven tested oat varieties could grow successfully in Hongyuan County,and the growth period of'Aba'was the shortest,only 120 days.The growth period of'monida'was the longest,up to 146 days.The fresh yield of oat varieties was 17 749.59~38 175.35kg/hm2,the hay yield of oat varieties was 4 990.88~9 230.26kg/hm2,and the seed yield of oat varieties was 1 242.777~2 453.96kg/hm2,among which the fresh yield and hay yield of'Mufeng'were the highest,and the seed yield of'Taisen'was the highest.The crude protein content of oat varieties was 8.69%~12.34%.The contents of acid detergent fiber and neutral detergent fiber of'Mufeng'and'monida'were at medium level,but better than the control variety'Aba'.The results of grey correlation analysis showed that the weighted correla-tion degree from high to low was:'Mufeng'>'monida'>'Molasses'>'Magnum'>'Taisen>'Haiwee'>'Aba',indi-cating that'Mufeng'and'monida'have the best comprehensive performance,which are suitable for planting in Northwest Plateau of Si-chuan.
