杂种优势早期鉴定,对于扩大亲本测配范围和数量,简化育种程序,加快品种选育速度具有重要意义。为此,我们在本所(忻县)试验了用酵母法预测高粱杂种优势。酵母法是苏联的马茨科夫提出来的,他所做的玉米试验认为:杂种优势与植物体内酵母活素类物质(主要为B族维生素)所含质量有直接关系,76%的组合表现为正结果。李继耕等(1964)以同样方法进行玉米杂种优势预测,共测定70个组合,与田间表现一致的达82.9%。宫春云等(1971)用同样方法进行了甘蓝型油菜杂种优势的预测,
Early identification of heterosis has important implications for expanding the range and number of parental assignments, simplifying the breeding program and speeding the breeding of varieties. For this reason, we tested the sorghum heterosis using the yeast method in our institute (Xin County). The yeast method was proposed by Matskov in the Soviet Union. The maize experiments he conducted concluded that the heterosis is directly related to the quality of the yeast yeast substances (mainly B vitamins) in the plants, and the combination of 76% Positive result. Li Jiguang et al. (1964) used the same method to predict the heterosis of maize and determined a total of 70 combinations, which was consistent with the field performance of 82.9%. Gong Chunyun et al. (1971) used the same method to predict the heterosis of Brassica napus,
