以从美国引进的高产杂交狼尾草Ｆ１为母本、优质的矮象草为父本进行有性杂交，杂交后代经多年的选育，育成比亲本质量更好、产量更高的杂交象草———桂牧１号。该草鲜草产量比母本、父本分别增产２６％和５５．２％；粗蛋白质含量比父本提高３．１５％，比母本提高３３．１６％；赖氨酸含量１．１４％，是一种高产高效新型牧草。
The crossbred F1 hybrid F1 was used as the female parent and the high quality hybrid dwarf grass was used as the male parent for the crossbreeding. After years of breeding, the offspring of hybrids were bred for better quality and higher yield of hybrid grass --- Gui Mu 1. The yield of fresh grass was 26% and 55.2% higher than that of the female parent and the male parent respectively. The crude protein content was 3.15% higher than that of the male parent, 33.16% higher than that of the female parent, and the lysine content was 1.14% , Is a high yield and efficient new grass.
