几年来,我们采用母株繁殖、小株留种交替进行的方法繁殖大白菜种子,在试验田内每年增加一定比例的小株采种面积,通过观察,发现由于采种田面积的增加,生产的大田用种的纯度也相应提高(见表)。 从上表可见,要获得较纯的大白菜小株种子,除播用母株繁殖的原种外,在符合隔离要求的前

Over the past few years, we adopt the method of breeding of mother plants and small-leaved plants alternately to breed Chinese cabbage seeds. In the experimental field, a certain proportion of small-sized plantings are increased every year. Through observation, it is found that, The purity of the species also increased accordingly (see table). As can be seen from the above table, to obtain a relatively pure Chinese cabbage small seed, in addition to the use of breeding mother of the original species, in line with the requirements of isolation
