了解谷子主要性状的遗传力和相关性,对于指导育种工作有一定意义。几年来,我们结合育种工作对谷子主要性状的遗传力、性状相关等进行了分析研究。一、试验材料及方法选用目前推广的品种做亲本,组合有繁峙黄×克育6号、齐头黄×黄玉2号、繁峙黄×蒙选1418。1976年得到子一代种子,1977年种植子二代。成熟后各组合随机取样50株,亲本各 Understanding the heritability and correlation of the main characters of millet has some significance for guiding the breeding work. In recent years, we combined with breeding work on the main traits of millet heritability, trait-related analysis. First, the test materials and methods to choose the current promotion of the species to do the parent, the combination of Fan Zhi Huang × Keyu 6, Qi Tou Huang × Topaz 2, Fan Zhi Huang × Mongolia election 1418. 1976 to get the first generation of seeds, 1977 Growers second generation. Mature randomly selected 50 combinations of each parent
