摘　　要：【目的】探明不同杂交木豆新品种(系)在贵州贵阳的生育期、株高、一级分枝数、茎叶比、营养成分和鲜草与种子产量的差异,筛选适宜贵阳及类似地区推广种植的杂交木豆新品种(系),为生产应用提供科学依据。【方法】采用随机区组试验方法,分析比较木豆201516、木豆201510、木豆ICPL87、木豆ICPL87091和木豆CAF2的生育期、株高、一级分枝数、茎叶比、营养成分、鲜草和种子产量等的变化。【结果】木豆201510和木豆201516的生育期较短、株高适中、生长势与抗病性较强;5个杂交木豆新品种(系)2年鲜草平均产量为59.22~67.18 t/hm^(2),以木豆201510最高,为67.18 t/hm^(2),木豆CAF2最低,为59.22 t/hm^(2),木豆201510较木豆CAF2、木豆ICPL87091和木豆ICPL87分别增产13.44%、12.17%和7.69%;5个杂交木豆新品种(系)2年种子平均产量为1841.33~4221.60 kg/hm^(2),木豆201516最高,为4221.60 kg/hm^(2),木豆CAF2最低,为1841.33 kg/hm^(2),木豆201516较木豆CAF2、木豆ICPL87091和木豆ICPL87分别增产129.3%、22.89%和32.41%;分枝期至开花期各品种(系)的粗蛋白质含量为12.77%~23.61%,粗脂肪含量为3.57%~6.65%,粗纤维含量为20.56%~37.27%。【结论】木豆201510和木豆201516较引进品种木豆ICPL87、木豆ICPL87091和木豆CAF2增产显著,叶量较丰富、营养价值较高、抗病性较强,适宜在贵州中低海拔地区推广种植。【Objective】The differences in growth period,plant height,primary branch number,stem-leaf ratio,nutritional component,fresh herbage yield and seed yield of different new hybrid Cajanus cajan varieties(lines)in Guiyang are explored,and the new hybrid C.cajan varieties(lines)which is suitable for planting and popularization in Guiyang and similar area are screened to provide the scientific basis for its production and application.【Method】The variation in the growth period,plant height,primary branch number,stem-leaf ratio,nutritional component,fresh herbage yield and seed yield of five new C.cajan varieties(lines)(201516,201510,ICPL87,ICPL87091 and CAF2)are analyzed and compared by a randomized block test.【Result】201510 and 201516 have the short growth period,moderate plant height,strong growth vigor and disease resistance;The two-year average fresh herbage yield of five new hybrid varieties(lines)is 59.22~67.18 t/hm^(2),201510 is the highest of 67.18 t/hm^(2),while CAF2 is the lowest of 59.22 t/hm^(2),the fresh herbage yield of 201510 is 13.44%,12.17%and 7.69%higher than that of CAF2,ICPL87091 and ICPL87 respectively;The two-year average seed yield of five new hybrid varieties(lines)is 1841.33~4221.60 kg/hm^(2),201516 is the highest of 4221.60 kg/hm^(2),while CAF2 is the lowest of 1841.33 kg/hm^(2),the seed yield of 201516 is 129.3%,22.89%and 32.41%higher than that of CAF2,ICPL87091 and ICPL87 respectively;The crude protein content,crude fat content and crude fibre content of different varieties(lines)from branching stage to flowering stage are 12.77%~23.61%,3.57%~6.65%and 20.56%~37.27%respectively.【Conclusion】201510 and 201516 are featured with yield increment,abundant leaves,high nutritional value and strong disease resistance compared with those of ICPL87,ICPL87091 and CAF2,which is suitable for planting and popularizing in middle and low altitude areas in Guizhou.
