摘要
为筛选适宜在高寒地区种植的粮饲兼用优质燕麦品种,在云南省迪庆藏族自治州格咱乡研究了11个皮燕麦品种的物候期、农艺性状、籽实产量及其构成因子,并对其进行综合评价。结果表明:各品种中,领袖的干草产量最高,为17060.93 kg/hm^(2),太阳神株高最高,达133.68 cm;贝勒及贝勒Ⅱ的茎粗超过10 mm;贝勒Ⅱ的叶长、叶宽均为最大。11个品种中,枪手籽实的粗蛋白含量最高,ESK籽实的粗淀粉含量最高,燕王籽实的可溶性糖含量最高,贝勒和贝勒Ⅱ籽实的亚油酸含量均高于40%,爱沃籽实的β-葡聚糖含量最高;籽实产量以贝勒Ⅱ、贝勒、太阳神较高,达4000 kg/hm^(2)以上;贝勒Ⅱ的主穗最长(31.30 cm)。籽实产量与主穗穗长呈极显著正相关(P<0.01)。运用灰色关联度综合评价法对11个燕麦品种籽实品质进行评价表明,贝勒Ⅱ表现最好,贝勒次之,适于迪庆高寒牧区作粮饲兼用。
To identify oat(Avena sativa)cultivars that are well-suited for grain-forage dual purpose cultivation in alpine regions,a comprehensive evaluation was conducted to investigate the phenological period,agronomic traits,seed yield and nutritional value of 11 oat varieties in Gezan Township,Diqing Tibetan Autonomous Prefecture,Yunnan Province.The results showed that Souris had the highest hay yield(17060.93 kg/hm^(2))and Titan had the tallest plant(133.68 cm).Baler and BalerⅡhad a stem diam⁃eter greater than 10 mm,and BalerⅡhad the largest leaf length and leaf width.Additionally,Shooter had the highest crude protein content in seeds,while ESK had higher crude starch content and Forge plus had the highest water soluble sugar content in seeds.Everleaf 126 had the highestβ-glucan content,and both Baler and BalerⅡhad more than 40%linoleic acid content in seeds.BalerⅡ,Baler,and Titan had the highest seed yields,with more than 4000 kg/hm^(2),and BalerⅡhad the longest main spike(31.30 cm).Seed yield was positively correlated with spike length(P<0.01).Based on the grey correlation method,the evaluation of seed quality revealed that BalerⅡperformed the best,followed by Baler,indicating their potential for used as both food and fodder in the alpine pasture of Diqing.
