Abstract: From 1986 to 1990, sorghum germplasms maintained in Henan province were evaluated for their tolerance to drought, cold, saline-alkali and infertile soil conditions, and resistance to, head smut, snout moth’s larva and aphid. Quality analysis was also conducted. The results showed that 29 varieties were cold-tolerant at seedling stages, 8 varieties were resistant to head smut with an incidence of below 12%, 9 varieties were resistant to snout moth's larva, 80 varieties were tolerant to infertile soil conditions. Through quality analysis, 7 varieties with protein content over 14%, 14 varieties with lysine content of sample over 2.6%, 22 varieties with lysine of protein content over 0.3%, 5 varieties with lysine both of protein content and of sample and 19 varieties with tannic acid below 0.1% were identified. Moreover, there were 12 germplasms with 2 or more desirable characters, and 2 germplasrns with 3 desirable characters. These are the most valuable sorghum resources of Henan province.
