摘要： 1986～1990年对河南省高粱品种资源（1046份）生物学特性的研究结果表明，苗期抗冷1级品种29个；苗期抗旱1级品种16个；苗期和芽期均耐盐的品种8个；发病率在12%以下抗丝黑穗病品种8个；抗螟1级品种9个；耐瘠1级品种80个。品质分析结果：蛋白蛋含量14%以上的品种7个；赖氨酸占蛋白含量2.6%以上品种14个，赖氨酸占样品含量0.3%以上品种22个，其中赖氨酸占蛋白、占样品均高的品种5个；单宁含量低于0.1%的品种19个；具2个和2个以上优异性状的种质12个，其中具3个以上优异性状的高粱种质2个，这些高粱品种资源是最宝贵的种质材料。实践证明，利用生物措施是稳定提高农业生产的有效措施。目前河南省推广面积较大的高粱品种多是抗性中上等，丰产性、品质较好的品种。

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.
