1 脱毒种薯、种苗的选育脱毒甘薯良种生产,需经茎尖分离,分化培养,组培苗培养,经病毒检测,获得无毒苗。在经扩繁、驯化获得脱毒零代苗;经隔离培养获脱毒原原种,再扩繁获得脱毒原种,继续扩繁得脱毒大田生产用种。1.1 无毒苗的获得在无菌组培室内,采集具有品种典型性状的生长健壮的秧头,长2～3cm,剥去叶片,消毒后用接种
1 virus-free seed, seed breeding virus-free sweet potato breeding, need to be separated by stem tips, differentiation and culture, tissue culture seedlings, virus detection, access to non-toxic seedlings. After multiplication and domestication to obtain zero-generation virus-free seedlings; obtained by isolating and cultivating the original stock of detoxification, and then expanded to obtain detoxification original species, continue to expand the detoxification field production of species. 1.1 non-toxic vaccine access In sterile tissue culture chamber, collecting the typical characteristics of the growth of robust seedlings, length 2 ~ 3cm, stripped of leaves, disinfected with vaccination
