摘　　要：为筛选适宜于四川丘陵地区种植的高产优质狼尾草属牧草,对4个狼尾草属牧草品种(系)进行2年大田试验,测定其重要农艺性状,并采用灰色关联度分析法对不同品种(系)9个性状指标进行综合评价。结果表明:‘CN002’的干草产量、越冬率均显著高于其他品种(系)的干草产量及越冬率(P<0.05),且鲜草产量、株高、叶片数优于其他品种(系);‘热研4号’叶长、叶宽显著高于其他品种(系)的叶长叶宽(P<0.05);‘CN001’的茎粗高于其他品种(系);‘桂牧1号’茎叶比表现优于其他品种(系)。应用灰色关联度对4种狼尾草属牧草品种(系)进行综合评价得出,‘CN002’较其他品种(系)更适宜在四川丘陵地区推广种植。The objective of this study was to identify superior-yielding and quality forage line within the Pennisetum genus in the hilly region of Sichuan Province.A two-year field experiment assessed four cultivars(lines),measuring key agronomic traits.The evaluation of nine trait indexes across different cultivars(lines)was performed using the grey relational degree analysis method.The results showed that‘CN002’demonstrated significantly higher hay yield and overwintering rates compared to other cultivars(lines)(P<0.05),along with better fresh yield,increased plant height,and leaf number.‘Reyan No.4’exhibited significantly greater leaf length and width than other cultivars(lines)(P<0.05).‘CN001’showed higher stem thickness than other cultivars(lines),and‘Guimu No.1’displayed a superior the stem-to-leaf ratio.The comprehensive evaluation,using the grey relational degree method,suggested that‘CN002’was more suitable for cultivation in the hilly regions of Sichuan Province.
