A New Processing Type White Radish Hybrid —‘Yunluobo No. 1’

According to the demands for producing dried processing white radish，this paper
taking a spring type radish male sterile line introduced from Korea as material and gained a male sterile
line 47A through transit breeding．In 2010，male sterile line 47A was crossed with inbred line 11015.
In 2011，a dried processing type new hybrid white radish named ‘Yunluobo No.1’ was bred．It has long
cylindrical root with green head and 2/3 part is buried in earth．Its root length is 45-50 cm，diameter
7-9 cm．The single root weight is 1.5-2.0 kg． The dry matter content is 8.7%，reducing sugar is 3.68%，
crude fiber is 0.45% and VC is 193 mg·kg^-1．It has good commercial and processing character．In
autumn sowing，its growth period is 70-120 days．Its resistance to downy mildew，virus and soft rot
diseases is stronger than‘naibingzongtai’in field investigation．It can yield fresh root about 75-135
t·hm-2．It is suitable to be cultivated in areas with altitude 1 700-2 400 m in Yunnan Province and other region with similar climate condition．
