玉米是我国主要粮食作物之一。长期以来,在生产上主要是运用常规育种的方法,获得玉米的自交系,进行杂交制种,利用杂种优势提高产量。这种获得玉米自交系的方法,不但配制的手续复杂,而且需要4—6年的时间。为了在很短的时间获得大量的自交系,可以采用玉米花药培养的方法培养出苗,只要将得到的苗用秋水仙碱溶液进行染色体加倍处理,当年就可以获得自交系。但是实践证明,玉米的花
Corn is one of the main food crops in our country. For a long time, the main method of production is the use of conventional breeding methods, access to maize inbred lines, hybrid seed production, the use of heterosis to increase production. This method of obtaining inbreds of maize not only complicates the procedure but also takes 4-6 years. In order to obtain a large number of inbred lines in a very short period of time, poplar can be cultured by the methods of anther culture. As long as the obtained seedlings are doubled with colchicine solution, inbred lines can be obtained in that year. But practice has proved that corn flowers
