摘　　要：为了筛选出适宜黑龙江地区种植的优质饲用高粱品种,试验在高粱孕穗期、开花期和成熟期收割,测定了饲用高粱的株高、茎粗、鲜草产量、干鲜比和干草产量。结果表明:不同饲用高粱品种生育进程存在明显差异,其中Ms1990、海牛、超卡、F10、3701、As6021、健宝、绿巨人不能够正常抽穗开花,在当地不能成熟。对饲用高粱鲜草产量进行测定,鲜草产量以Ms1990最高,为962 80.42 kg/hm^2;帕卡鲜草产量最低,为433 53.17 kg/hm^2。高粱品种干草产量从高到低依次为3701>Ms1990>As6021>F10>健宝>As6017>绿巨人>6022>海牛>As6013>YCS>超卡>BT>绝佳>龙甜1号>牛魔王>6015>6023>帕卡。This study was designed to deter mine plant height, stem diameter, fresh yield, dry weight/fresh weight ratio and hay yield at the booting,flowering and maturing stages of forage sorghum in order to screen higher quality breed of forage sorghum suitable for planting in Heilongiiang region. The results demonstrated that the growth progress between different breeds of forage sorghum had the existence of significant difference. Among the breeds including Ms1990, Hainiu, Chaoka, F10,3701, As6021, Jianba0 and Lvjuren were abnormal during the heading and flowering stages, and also could not be mature in Heilongjiang region. The fresh yields of different forage sorghum breeds were measured and the most yield of 962 80.42 kg/hm2 was for the Ms1990 breed while the least one of 433 53.17 kg/hm2 for the Pake. The hay yields of 19 forage sorghum breeds were in sequence from the most to the least below ：3701 〉 Ms1990 〉 As6021 〉 F10 〉 Jianbao 〉 As6017 〉 Lujuren 〉 6022 〉 Hainiu 〉 As6013 〉 YCS 〉 Chaoka 〉 BT 〉 Juejia 〉 Longtian No. 1 〉 Niumowang 〉 6015 〉 6023 〉 Paka.
