Abstract:

In order to enrich the genetic resources of Chinese kale and improve the level of kale hybrid breeding, ‘Qiubao kale', a new hybrid kale variety prepared by using cytoplasmic male sterile line, was bred. The variety has the characteristics of medium maturity, excellent quality and good marketability. The leaves of ‘Qiubao kale' are nearly round, with a leaf length of 16.0 cm and a leaf width of 15.7 cm. The stem is 19.8 cm in length and 1.8-2.0 cm in thickness, and the mass of a single stem is 100-120 g. It takes 55-60 days from sowing to first harvest. The average yield of the regional test is 9593.9 kg/hm2, an average increase of 11.0% compared with that of the control variety ‘Shunbao kale'. ‘Qiubao kale' has strong waterlogging tolerance, disease resistance and wide adaptability, and its suitable sowing period in Guangzhou is from September to late November.
