REPORT ON OAT VARIETY INTRODUCTION AND COMPARISON TRIAL

1 997～ 1 999年 ,在西宁及果洛不同地区的引种栽培和品种比较试验结果表明 :6种燕麦在西宁地区种子均成熟良好。永久 0 0 1表现早熟 ,YTA、青海 444中熟 ,MELYS、LENA、NEON晚熟 ;MELYS、LENA和青海 444籽实产量较高 ,其总穗数、穗粒数、千粒重综合性状较好 ,产量结构合理 ,具有高产性能 ;北欧引进的燕麦品种表现为植株高大、生育期长、籽实产量高的特性 ;LENA和永久 0 0 1干草和蛋白质产量均较高 ;北欧引进的晚熟品种适于相对低海拔地区种植 ;MELYS、YTA及永久

Trials on introduction and comparison of varieties of oats in Xining and Guoluo showed that 6 varieties could produce seed in Xining. Yongjuo001 ripened early, YTA, Qinghai444 ripened normally, MELYS, LENA, NEON ripened late. Seed production of MELYS, LENA and Qinghai444 were high. General characteristics of yield such as total number of ears, kernel numbers in an ear and weight of 1000 kemels showed good yield structure and productivity. Varieties from Northern Europe had high plant germination, long growth period and good seed production. LENA and Yongjuo001 produced good quantity of forage and protein content. Late ripening European Varieties were adapted to low altitude. Quality of fodder of MELYS, YTA and Yongjuo473 was better than other varieties.
