| Abstract: | An autotetraploid non heading Chinese cabbage Zaoyoudong( Brassica campestris ssp.chinensis Makino)was developed from its diploid sibling plants with green stalk,through colchicine treatment on shoot tips.The autotetraploid was used in the cross with autotetraploid cultivars Shuzhouqing(high quality)and their F 1 was used in an additive cross with autotetraploid cultivar Reyou No 2(heat resistance)for selection of self incompatible lines,based on morphological and physiological characters.After repeated selfing and selection,self incompatible lines G SI and E SI were developed and used as parent to produce F 1 hybrid cultivar Shuyou No 1,which is characterized by green stalk,high quality and heat resistance. |
