百色地区历年来玉米播种面积在200万亩以上,约占全地区粮食作物总播种面积的35—40%。但亩产较低,多年来徘徊在200斤左右。低产的原因是多方面的。但在品种问题上,多年来,大面积采用的是农家种,单产低;单交种产量虽高,但基因型单一,遗传基础狭窄,适应性有限,繁殖制种麻烦,种子成本高,推广面积受到限制。1978年12月从广西玉米研究所引进墨白一号(Tuxpeno 1)、94号(Tuxpeno P.B.C_(15))两个玉米改良群体(以下简称“墨白
Over the past years, the area under maize planting in Baise has reached over 2 million mu, accounting for 35-40% of the total sown area of food crops in the entire region. However, the yield per mu is rather low, hovering around 200 kilos for many years. The reasons for low yield are many. However, on the issue of variety, over the years, large-scale adoption of farmhouses has led to a low yield. Although single-seed production is high, it has a single genotype, narrow genetic base, limited adaptability, troubles in breeding and breeding, high seed cost, popularization Area is limited. In December 1978, two maize improved populations (Tuxpeno 1 and 94) (Tuxpeno P.B.C_ (15)) were introduced from Guangxi Corn Research Institute (hereinafter referred to as "Mo Bai
