Abstract Youqie02’and‘Zaoqie’ were carried by‘Article 18 Retuning-type Science Technology and Experimental Satellites’and‘Shenzhou-4’spaceship, respectively and treated by space mutation. Two high purity lines 036-5-3 and 023-1-4-7 were selected after 5 generations of self-cross, respectively. Hybrid of these two lines, a new variety‘Hangqie No.6’was developed, which was early maturing. It matures about 108 days after sowing. The plant is upright with green stem, circular fruit top and its fruit is of long oval-shape, with purple-black and polish puricarp. It is 28-35 cm in length, 5-7 cm in diameter and 300-350 g in weight. Its VB1, glucose, protein and VC contents are about 0.1 mg•kg-1, 11 g•kg-1, 20 g•kg-1, and 58 mg•kg-1. This cultivar is tolerant to low temperature and dim light, and has stronger resistance to Verticillium wilt and brown grain disease than‘Jingxuanzaokangqie’and‘Mounika’. Its yield is about 75 t•hm-2. It is suitable for cultivation in northern region in protected fields in early spring and greenhouse in winter.
