Cytogenetical studies on hybrids between S.sudanense and S. bicolor

摘要：

SudangrassSorghum sudanense (piper) stapfand sorghum Sorghum bicolor(L) Moench are two members of the genus Sorghum (Gramineal) (Lu,1999).Their Hybrid has exhibited favorable forage yields and overall improved quality and disease resistance.They are widely used in aquaculture, production of livestock food and environmental protection (Zhan et al.,2008), but some disagreement exists as to whether they actually belong to the same species.We studied the relationship between sudangrass (S. sudanense) and sorghum (S.bicolor) using cytogenetical characters of 2 sudangrass varieties, 2 sorghum varieties, 3 F1 hybrids and 2 F2 hybrids.
