摘  要：
【目的】筛选综合性状较优的饲草谷子品系,为赤峰地区饲草谷子品种选育提供理论依据.【方法】对15个饲草谷子品系和CK(‘饲谷5号’)的生育期、草产量、株高和营养特性等进行比较研究,并运用灰色关联度分析法对供试材料的生产性能进行综合评价.【结果】除CK和‘赤草11号’外,其他品系均能在赤峰地区完成整个生育期,生育期为124～131 d,其中‘赤草13号’的生育期最短,‘赤草1号’和‘赤草9号’的生育期最长.‘赤草5号’‘赤草7号’和‘赤草13号’的株高优于其他品系和CK,成熟期株高达到190 cm以上.‘赤草3号’‘赤草5号’和‘赤草13号’的干草产量最高,分别为12.69、12.54和12.02 t/hm~2.‘赤草7号’‘赤草5号’和‘赤草13号’的粗蛋白含量最高,分别为12.66%、12.57%和12.39%.根据灰色关联度分析综合评价排在前3位的为‘赤草5号’‘赤草3号’和‘赤草13号’.【结论】‘赤草5号’‘赤草3号’和‘赤草13号’综合表现好,适于进行一步进行区域试验和生产试验.

摘  要：
【Objective】 To screen out the forage millet lines with better comprehensive performance and provide the foundation for breeding new forage millet varieties.【Method】 The adaptability of 15 forage millet lines and CK(Sigu 5) were studied by testing the growth period,grass yield,plant height and nutritional characteristics,and the production performance of different lines were also evaluated with grey correlation analysis.【Result】 Except for CK and Chicao No.11,all tested lines could complete the growth period within 124 to 131 days,and Chicao No.13 was the shortest,Chicao No.1 and No.9 were the longest.The plant height of Chicao No.5,No.7 and No.13 were higher than that other lines and CK,and it was over 190 cm in maturity stage.Chicao No.3,No.5 and No.13 had the highest hay yields(12.69,12.54 and 12.02 t/hm~2,respectively).The crude protein contents of Chicao No.7,No.5 and No.13 were the highest(12.66%,12.57% and 12.39%,respectively).According to the gray correlation analysis,the top three lines were Chicao No.5,No.3 and No.13.【Conclusion】 The comprehensive performance of Chicao No.5,No.3 and No.13 is the best.
