玉米是我省的主要粮食作物之一,占粮食总播种面积的32%,占粮食总产的30%左右。积极选育玉米杂交种,对迅速提高粮食产量、落实毛主席“备战、备荒、为人民”的伟大战略方针,具有深远的意义。几年来,我们遵照毛主席“有了优良品种,即不增加劳动力、肥料,也可获得较多的收成”的教导,采取从地方品种自交分离与从外引优良自交系进行鉴定整理,并到海南岛冬繁加速世代进程的方法选育一批自交系,组配了部分杂交组合。现分别简介如下。
Corn is one of the main grain crops in our province, accounting for 32% of the total grain sown area and accounting for about 30% of the total grain output. Active breeding of corn hybrids has far-reaching significance in rapidly raising grain output and implementing Chairman Mao’s great strategic guideline of “preparing for war, preparing for waste and serving the people.” In the past few years, following the guidance of Chairman Mao’s “excellent varieties, that is, more fertility can be obtained without increasing labor force and fertilizers,” we follow the principle of self-isolation from local varieties and identification of fine inbred lines from the outside, And to Hainan Island to speed up the process of generation multiplication breeding a number of inbred lines, with some hybrid combinations. The brief introduction is as follows.
