大白菜的营养生长期和采种繁殖期是分开的,按常规每年只能于秋季进行一次对经济性状的选择,为了加快育种速度,提高选择效果,改进育种方法,对春播采种株与秋后代间的性状相关性进行了研究,以便获得相关选择的参数根据,探索其规律性。试材与方法 1983、1984年,试材为“青麻叶”、“莱芜”、“青帮河头”、“辽阳牛心”、“小青口”、“唐山快菜、“油六”、“早皇白”、“河头早”、“灰堆核头纹”,共10个品种,
The vegetative growth stage of Chinese cabbage is separate from that of the seed breeding stage. According to the conventional practice, economic traits can only be conducted in the autumn once in a year. In order to speed up the breeding process, improve the selection effect and improve the breeding method, The correlation of traits was studied in order to obtain the parameters of the relevant selection basis and explore its regularity. Test materials and methods In 1983 and 1984, the test materials were “Green Soybean Leaf”, “Laiwu”, “Green Ganghe Head”, “Liaoyang Beef Heart”, “Xiaoqingkou”, “Tangshan Fast Food, ”Early Huangbai“, ”river early“, ”ash pile nucleus", a total of 10 varieties,
