| 摘 要： | 以甘肃省临洮县种植的10份饲料型小黑麦新品系为试验材料,甘农1号小黑麦和新小黑麦5号为对照,研究了小黑麦材料的种子产量及籽粒的营养价值,采用灰色关联度法对参试材料的种子产量与营养品质进行了综合评价。结果表明:不同小黑麦材料间种子产量和营养价值均存在显著性差异,Z49的种子产量最高,达11 133.50kg/hm~2,Z48的粗蛋白含量最高,为14.04%,Z5的淀粉含量最高,为65.69%,Z35的赖氨酸含量最高,为0.46%,Z3的粗脂肪含量最高,为2.37%。综合分析表明,Z48和Z49的综合性状最佳,其关联度分别为0.713 6和0.786 4,Z19和Z23的综合表现较差。

| Abstract: | The seed yield and grain nutritional value of 10 new Triticale lines were studied in Lintao County,Gansu Province,and two released triticale varieties,Gannong No.1 and New Triticale No.5 were used as the controls.The gray relational grade analysis was used to comprehensively evaluate the seed yield and grain nutritional value.Results showed that the significant differences existed in seed yield and grain nutritional value among different triticale materials.Z49 had the highest seed yield (11 133.50 kg/hm2),Z48 had the highest CP content (14.04%),Z5 had the highest CS content (65.69%),Z35 had the highest lysine content (0.46%),and Z3 had the highest EE content (2.37%).Comprehensive analysis indicated that Z48 and Z49 had better performance and the comprehensive value was 0.713 6 and 0.786 4,respectively.Z19 and Z23 had poor comprehensive performances. |
