我省玉米杂交种优势的利用研究工作,是在毛主席革命路线指引下,建立和发展起来的。1947年在鲁南解放区的山东省农业实验所开始研究地方玉米良种和培育自交系的工作;1953年推广品种间杂交种,1959年推广双交种;1967年全省基本普及双交种。在无产阶级文化大革命的推动下,玉米杂交种优势利用以单交种为主,实行单交种、三交种、双交种的综合利用,得到全面发展,特别是在英明领袖华主席的领导下,一举粉碎“四人帮”,科研工作大解放。我们决心力争在今后五年、十年內,进一步搞好玉米杂种优势利用的研究,在科学技术上有个较大的突破,对社会主义建设做出应有的贡献。现将们工作中的几点体会,简述如下:
The research on the utilization of the advantages of maize hybrids in our province was established and developed under the guidance of Chairman Mao’s revolutionary line. In 1947 in Shandong Lugong liberated areas of Shandong Agricultural Experiment began to study the local corn varieties and inbred lines of work; 1953 to promote inter-species hybrids, popularized in 1959, double-crosses; 1967 basic popularization of the province. Under the impetus of the Great Proletarian Cultural Revolution, the utilization of maize hybrids has been dominated by single cross-breeding, and the comprehensive utilization of single cross-breeding, three-cross breeding and double cross breeding has been fully developed, especially in the leadership of wise leader Chairman Hua In one fell swoop, the “gang of four” was crushed and the scientific research was liberated. We are determined to strive to further improve the utilization of maize heterosis in the next five to 10 years and make a big breakthrough in science and technology and make due contributions to the socialist construction. What are some of the experience in their work, briefly described as follows:
