摘　　要："闽牧6号"狼尾草是通过辐射杂交狼尾草杂种F1种子诱变和田间双重筛选选育的狼尾草新品种,杂交狼尾草F1种子为美洲狼尾草不育系Tift23A为母本和象草N51为父本配制的种间杂交种,为三倍体杂种,其染色体数为3n=21,其中7条染色体来自美洲狼尾草,14条来自象草。"闽牧6号"狼尾草鲜草产量高(最高可达348 400kg/hm2)、品质优(粗蛋白质15.30%)、茎叶比低(0.56),在福建省3～9月均可用茎节繁殖,株行距以50cm×50cm或40cm×60cm为宜。为获得高产,每次刈割后要及时追肥,"闽牧6号"狼尾草极少有病虫害发生,偶见蚜虫,其鲜草适合饲喂牛、羊等草食动物,也可青贮利用,还可打浆适量饲喂生猪,多余的青草晒制后也可替代稻草栽培双孢蘑菇。Minmu-6 is a new variety of pennisetum produced through radiation breeding of hybrid F1 and double screening in the field, which has the characteristics of high yield （the maximum 348400kg/ hm2）, superior quality（ CP 15.30%） and low ratio of stem and leaf（0.56）. In Fujian province, it can be reproduced with eustipes from March to September, with a 50crux 50cm or 40cm×60cm spacing. In order to gain high yield, manure should be added after each mowing. Minmu-6 is less likely to be damaged by diseases and insects with an exception of accidental aphis. Its fresh grass can be either fed to cattle and sheep or stored in addition to feeding the pig by pulping with the diet, and the additional grass after suncuring can be used to plant Agaricus bisporus instead of straws.
