摘　　要：【目的】为客观评价红豆草新品系的生产性能,为新品系的示范推广及品种审定提供基础数据。【方法】试验以新疆农业大学选育的3个红豆草新品系ND056-1、ND056-2、ND056-3为材料,以奇台红豆草为对照(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,四个材料的物候期无差异,ND056-3的平均株高最高为104.2 cm,ND056-2的次之为104.13 cm,CK最低为103.07 cm;ND056-1的干鲜比最高为30.15%,是对照的1.22倍,ND056-2最低为23.73%,是对照的0.96倍;ND056-3的叶茎比最高(1.2266),ND056-2次之(0.9918),分别是对照的1.1倍和1.38倍;全年鲜草产量中,ND056-3的最高为70.58 t/hm^(2),ND056-1次之为66.25 t/hm^(2),分别是对照的1.247倍和1.170倍;全年干草产量中,ND056-1的最高为19.89 t/hm^(2),ND056-3次之为19.32 t/hm^(2),分别是对照的1.30倍和1.27倍。【结论】综合分析认为,新品系ND056-3适合作为青鲜草利用,ND056-1适合作为干草利用。【Objective】In order to evaluate production performance of the new varieties of Onobrychis viciaefolia,and to provide basic data for their demonstrating and promoting as well as variety certification.【Methods】Three new varieties of Onobrychis viciaefolia(ND056-1,ND056-2 and ND056-3)cultivated by Xinjiang Agricultural University were used as experimental materials,and the Qitai variety as a control(CK),the production performance was comprehensively evaluated by observing indicators such as growth period,plant height,dry-fresh ratio,stem-leaf ratio,fresh grass yield,and hay yield.【Results】The results showed that there was no difference in the phenological period of the four varieties.The average plant height of ND056-3was the highest(104.2 cm),followed by ND056-2(104.13 cm)and that of CK was the lowest(103.07 cm).The dry-fresh ratio of ND056-1 was the highest(30.15%),which was 1.22 times than that of the control,and ND056-2 was the lowest(23.73%),0.96times than the control.The leaf-stem ratio of ND056-3 was highest with 1.2266,followed by ND056-2 with 0.9918,which were1.1 and 1.38 times than the control,respectively.The highest of annual fresh grass yield was the ND056-3 with 70.58 t/hm^(2),followed by ND056-1 with 66.25 t/hm^(2),which were 1.247 and 1.170 times than the control.The highest annual hay yield was the ND056-1 with 19.89 t/hm^(2),followed by ND056-3 with 19.32 t/hm^(2),which were 1.30 and 1.27 times that of the control,respectively.【Conclusion】As a conclusion,the ND056-3 was suitable for use as fresh grass,while ND056-1 as hay.
