摘　　要：本文主要论述了有关中国狼尾草属牧草资源发掘与开发利用前景等问题。中国狼尾草属牧草包括常见种,引进种以及新发现的新种和新变种目前共计有12种、3变种。为加快狼尾草属牧草资源的开发及利用,中国狼尾草属牧草有野生种1常见种、2新种、2新变种,合计5种共7份材料已经初步种质监定和田间选系比较试验。监定、试验结果,各参与试验种及变种农艺和经济性状表现优良。The number of species and varieties in the Genus Pennisetum Rich. is composed of commonly used and introduced as well as newly discovered, altogether 12 species(including the formerly identified 4 species, P, alopecuroides Spreng., P. centrasiaticum Tzvel., P. purpureum Schumach. and P. glaucum R. Br. )and 3 varieties until quite recently. According to our study, it was indicatde the following species inclusive of varieties, P. pianningense(S. L. Zhong)S.L. Chen et Y. X. Jin, sp. nov., P.longissimum S. L. Chen et Y. X. Jin, P. longissimum var.intermedium S. L. Chen et Y. X. Jin, var. nov. and P. centrasiatictum var. lanpingense S. L. Chen et Y. X.Jin var. nov.,are relatively excellent in consequence, with their early maturity, rich in leafiness, abundant in forage yield as well as high in crude protein content, etc. Besides, the paper has been discussed by the authors on the problems of exploitation, development and utilization of these fore—mentioned forage species and varieties germplasm resources.
