Abstract:‘Yunchunbai No.4’is a new Chinese cabbage F1 hybrid bred by crossing self-incompatible lines‘14251’and‘CM13241’as parents.Its growing period is 70-80 days.The plant has strong growth vigor and compact type.Its outer leaves are dark green in color,and inner leaves are golden yellow in color. The plant is 23 cm in height and 58 cm in width.Its head is 23 cm in height and 10-11 cm in diameter.The spherical index is 1.8,and net-head rate is 71.6%.Its net vegetable yield is about 79.5 t · hm-2.The soluble sugar content is 2.21% and VC content is 219.0 mg · kg-1.Its resistances to virus disease,downy mildew and soft rot in fields are equal to that of the contrast‘Chunyuehuang’.It is suitable for planting in major vegetable producing regions of Guizhou and Yunnan Provinces with 1 600-2 000 m high altitude in spring and autumn.
