加速棉花世代的方法很多,有利用自然气候条件到海南岛去冬繁的,也有人工采用试管培养和温室培养等方法的。为加速棉花育种进程,我们利用温室控制棉花的生长发育所需的温度,缩短生育期。在南京19810年秋获得的杂交种子,到1981年10月底获得杂种第三代,大大缩短了育种进程。1、杂种第一代。1980年11月13日,把当年收的杂交种子,先用水浸一夜,拌多菌
There are many ways to speed up the generation of cotton. There are many methods that make use of the natural climatic conditions to go to winter in Hainan Island, and also artificial methods such as test tube culture and greenhouse cultivation. In order to speed up the cotton breeding process, we use the greenhouse to control the temperature needed for the growth of cotton and shorten the growth period. The hybrid seeds obtained in Nanjing in the autumn of 19810 won the hybrid third generation by the end of October 1981, greatly shortening the breeding process. 1, hybrid first generation. November 13, 1980, the year of hybrid seeds received, first with water overnight, mix more bacteria
