摘要
Abstract
‘Qingnong 55’ is a new crack-tolerant cabbage variety developed by crossing cytoplasmic male sterility (CMS) line A05-1-3-15 as female parent with self-compatible line Heyin-1 as male parent. It is of early maturity. It takes 50-55 days from transplantation to harvest. Its head crack rate 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. The average single head weight in initial harvest period is about 1.2-1.4 kg. The total yield can reach 67.5 t·hm-2 for open field in autumn and over 75 t·hm-2 for simple plastic tunnels in spring. This variety is resistant to black rot and tolerant to downy mildew. It is suitable to be planted in northern China in spring in protected land and in autumn in open fields.关键词
