绿菜花(又称西兰花)杂种一代的生产,现世界上多采用自交不亲合系制种。近年来,国外种子商曾多次在我国北方地区进行了绿菜花自交不亲合系的种子生产尝试,但由于其生长周期长,生活力弱,结实率低的特性和东北冬季寒冷,夏季炎热,春秋较短的气候原因,造成东北地区无法在露地直接生产,而保护地种子生产又因技术不过关而失败,影响了出口创汇,并且至今仍无这方面的研究报导。基于这种情况,于1993年秋季开始,我们对绿菜花自交不亲合系种子的生产方式和采种技术进行了初步研究。
Green cauliflower (also known as broccoli) hybrid generation, the world is now more use of self-incompatibility seed production. In recent years, foreign seed traders have repeatedly tried seed production in green cauliflower self-incompatibility in northern China. However, due to its long-term growth cycle, weak vitality and low seed setting rate, cold in the northeast and summer Hot, short spring and autumn climate causes Northeast China can not be directly produced in the open field, and the protection of seed production because of technology but failed, affecting the export earnings, and so far there is no research reports. Based on this situation, in the autumn of 1993, we conducted a preliminary study on the production methods and seed collection techniques of greencross self-incompatible seeds.
