CCM: Brief introduction to new crack-tolerant cabbage cultivar Qingnong55 09-23-2016

With cytoplasmic male sterility (CMS) line A05-1-3-15 as female parent and self-compatible line Heyin-1 as male parent, Qingnong55 is a new early-maturing crack-tolerant (50-55 days from transplantation to harvest) cabbage variety.  

 

Head crack rate of the plant is less than 0.5% within 15 days after its maturity. The outer leaves are about 12 pieces and shining green in color. Its head is round and about 16-18 cm in length. The inner leaves are light yellow in color and taste sweet and crispy. Its central axis is extremely short, about 1/2 of the head height. Moreover, this variety is resistant to black rot and tolerant to downy mildew.

 

Regarding its output, each 667 m2 can yield 4,500 kg of fruit for open field in autumn and over 5,000 for simple plastic tunnels in spring (about 1.2-1.4 kg in weight in initial harvest period per head). This variety is suitable to be planted in northern China in spring in reserve land and in autumn in open fields.
