Embodiment 1

[0019] Using 0.1% to 0.05% male sterile plants in Jiangsu local radish variety "Dahongpao" (publicly known in production) as the source of sterility, using Shandong local radish variety "Chuanxinhong" (publicly known in production) No. 6 The generation inbred line c152b is the breeding material, and the pedigree of c152b selection is as follows figure 1 As shown, a set of male sterile lines of radish were obtained after 6 generations of backcrossing, namely: male sterile line c152a and male sterile maintainer line c152b. figure 2 shown. The male sterile line c152a not only maintains the characteristics of the sixth generation inbred line c152b of "Chuanxinhong", but also has a sterility rate and degree of sterility of 100%; the inbred line c152b of "Chuanxinhong" is late-maturing and of good quality , high yield, 85-95 days of growth period, fleshy root with red skin and white flesh, root length 22cm-26cm, root diameter 4cm-6cm, cylindrical shape, good quality, not easy to b...

Abstract

The invention discloses a breeding method of radish with purple peel. According to the method, a male sterile plant of a 'dahongpao' radish is used as a sterile source, a six-generation selfing line c152b of a 'cuanxinhong' radish is used as a transformation material, and a male sterile line c152a is obtained by six-generation backcross. A 'baiyuchun' radish is used as an original material, and a high-generation selfing line s-4-3-2-5-1-6-3 with stable inheritable characters can be obtained by seven-generation single plant selfing. The male sterile line c152a is used as a female parent, and the high-generation selfing line s-4-3-2-5-1-6-3 of 'baiyuchun' is used as a male parent, so that one-generation hybrid variety, named as 'ziyu', of the radish with the purple peel can be obtained by hybrid of the male parent and the female parent. According to the obtained variety 'ziyu', the upper half part of the surface peel of a radish is light purple, the lower half part of the surface peel of the radish is white and white like the color of meat, the root peel of the radish is smooth, the peel of the radish is thin, the radish meat is relatively crisp, the content of water in the radish is relatively high, the radish has the flavors of a white radish and a red radish, the yield is high, and the radish with the purple peel can be suitable for cultivation in autumn and cultivation overwintering or in early spring in greenhouses in the middle and lower reach areas of Yangtze river.

Description

technical field [0001] The invention belongs to the technical field of plant breeding and relates to a method for breeding purple radish. Background technique [0002] What the existing purple-skinned radish breeding adopts is the conventional breeding method, that is: use the existing purple-skinned radish variety or red-skinned radish variety resources as parents, paired and crossed, and the hybrid offspring undergoes self-crossing, separation, and purification for 5 to 7 days.
