为探讨广西南部地区能否可以进行冬季杂交玉米制种,广西区种子公司从1990年冬开始至今连续进行三冬试验,参试的杂交玉米组合共10个,其中属区内当家组合6个,省外掖单系列4个。三年共制种面积413.9亩,获得种子总产50438.37公斤,平均亩产121.86公斤,当中最高产有29.3亩,收入种子产量7852.8公斤,平均亩产268公斤,超过秋季制种产量6%左右。此项目最近已通过省级专家鉴定,认为可广泛利用。广西区种子公司组织进行杂交玉米冬季制种试验,是选择在该省南部的合浦、防城、博白、崇左、钦
In order to investigate whether winter hybrid corn can be planted in southern Guangxi, Guangxi Seed Company conducted three winter trials continuously from the beginning of winter 1990 to the present. A total of 10 hybrid corn combinations were tested, of which 6 were mandarin, Yedai outside the series of four. In the past three years, a total area of 413.9 mu was planted and the total output of seeds was 50438.37 kilograms. The average mu yield was 121.86 kilograms. Among them, the highest yield was 29.3 mu, the income seed yield was 7852.8 kilograms, and the average mu yield was 268 kilograms, more than 6 percent of autumn seed production. This project has recently passed the provincial expert appraisal, that can be widely used. Guangxi seed companies organized hybrid winter corn seed production test is to choose in the southern province of Hepu, Fangcheng, Bobai, Chongzuo, Chin
