摘　　要：【目的】旨在客观评价红三叶新品系的生产性能,为新品系的示范推广及品种审定提供基础数据。【方法】以新疆农业大学选育的3个红三叶新品系(HSY6、HSY11、HSY12)为研究对象,以蒙农1号红三叶(TrifoliumpratenseL.cv.MengnongNo.1)为对照(CK),通过观测生育期、株高、干鲜比、茎叶比、鲜草产量、干草产量等指标,对其生产性能进行综合评价。【结果】研究结果表明,4份材料的物候期无显著差异;HSY12的平均株高最高,为70.52 cm,CK的次之,为68.87 cm,HSY6最低,仅为64.77cm;HSY11的干鲜比最高,为20.16%,是对照的1.03倍;HSY6的叶茎比最高(0.9427),HSY11的次之(0.8834),分别是对照的1.17倍和1.05倍;全年(三茬)鲜草产量中,HSY11的最高,为130.70 t/hm^(2),CK的次之,为120.93 t/hm^(2);全年(三茬)干草产量中,HSY11的最高,为26.80t/hm^(2),CK次之,为23.30t/hm^(2)。【结论】综合分析认为,与其他3份材料相比,新品系HSY11更适合作为青鲜草和干草利用。【Objective】To objectively evaluate the production performance of three strains of Trifolium pratense(HSY6,HSY11,HSY12)and to provide basic data for their demonstration,promotion,and variety approval.【Methods】Three Trifolium pratense strains(HSY6,HSY11,HSY12)selected and bred by Xinjiang Agricultural University were used as materials in the experiment,and Mengnong No.1(Trifolium pratense L.cv.Mengnong No.1)was used as the control(CK),and their production performance was comprehensively evaluated by observing the indexes of fertility period,plant height,dry-to-fresh ratio,stem-to-leaf ratio,fresh herbage yield and dry herbage yield.【Results】There was no difference in the phenological period of the four materials;the average plant height of HSY12 was the highest(70.52 cm),followed by CK(68.87 cm),and HSY6 was the lowest(64.77 cm);the dry-to-fresh ratio of HSY11 was the highest(20.16%),which was 1.03 times that of the control;the stem-to-leaf ratio of HSY6 was the highest(0.9427),followed by HSY11(0.8834),1.17 and 1.05 times of the control,respectively;the annual(three-crop)fresh grass yield of HSY11 was the highest(130.70 t/hm^(2)),and CK was the second highest(120.93 t/hm^(2)),the annual(three-crop)dry yield of HSY11 was the highest(26.80 t/hm^(2)),and CK was the second highest(23.30t/hm^(2)).【Conclusion】HSY11 is more suitable to be used as fresh grass and hay than the other three materials.
