By 1986, several male sterile lines, restorer lines and more promising hybrids have been bred. Monograph 301 infertility single cross breed, in the seed production process, the parent line need not to male. From 1983 to 1986, the internal ratio test results, the average yield of 657 kilograms, compared with the control of the Jidan101 yield 28.3%. According to several years of breeding and seed breeding practice, the production of maize hybrids supporting the use of male three lines as follows: First, the use of male sterile lines to formulate the meaning of corn hybrids 1. Can save the labor force to reduce the farming system, reduce Seed students
