1981年自美国引进狼尾草的杂交种三个株系的第一代种子.这三个株系都是以多年生的象草为父本,一年生美洲狼尾草为母本的杂交种.其中两个株系在1981年获得了有性后代,目前已获得第五代种子.由于后代(特别第二代)分离的类型极多,我们除继续加代选育外,采取杂交优势最好的一个杂交一代植株,用无性繁殖进行了观察和有关的试验.三年的试验证明,其饲料产量、营养价值、抗逆性等均优于其父本象草,是一种高产优质的饲料作物,目前已在我省进行多点试种示范.
The first generation of three lines of Pennisetum hybrids was introduced from the United States in 1981. All three lines are hybrids of perennial grassy-headed, annual American Pennisetum as the female parent. The two lines obtained sexual descendants in 1981 and now have the fifth generation of seeds. Since there are many types of offspring (especially the second generation), we adopt the best heterosis The hybrid generation plants were observed and related experiments with vegetative propagation.After three years of experiments, the results showed that the yield, nutritional value and stress resistance of the hybrid plants were better than their male parents like grass, which was a high-yield and high-quality forage crop, At present, we have carried out more demonstration projects in our province.
