[0021] (1) Use the parents of the cauliflower hybrid "Shenxue 108 days" as the experimental material, the cytoplasmic male line AW-100 as the female parent, and the inbred line C-3 as the male parent, referring to the SSR analysis method of Uzunova and Ecke (1999) , optimize the SSR molecular labeling reaction system, the SSR molecular labeling reaction system is as follows: MgCl 2 , 2.5mmol·L -1 , dNTPs 0.2mmol L -1 , 100ng SSR primers, 0.1U Taq polymerase, 1μl 10×PCRBuffer, 35ng "Shenxue 108 days" DNA template;

[0022] (2) Using the parents of the cauliflower hybrid "Shenxue 108 days" as experimental materials, using the optimized SSR molecular marker reaction system, 26 pairs of polymorphic SSR marker primers were screened, including BRMS05, BRMS06, BRMS08, BRMS15 , BRMS16, BRMS25, BRMS30, BRMS36, BRMS42-2, BRMS54, BRMS71, BRMS296, BRMS324, Bn38A, Bn59A, ENA4, ENA7, E...

Embodiment 2

[0028] (1) Material

[0029] This example uses "Shen Xue 108 Days" and "COMS05×B1" as experimental materials.

[0030] (2) Experimental method

[0031] SSR analysis method: refer to Uzunova and Ecke (1999). The primers were BRMS05 primers and BRMS36 primers, which were synthesized by Shanghai Bioengineering Company.

Abstract

The invention belongs to the technical field of molecular organisms and particularly relates to a fingerprint spectrum of cauliflower hybrid and a construction method thereof. The cauliflower hybrid is temporarily named as 'shenxue 108 day', and is a new cauliflower variety bred by multi-year hybrid in Shanghai funong seed industry limited company. The fingerprint spectrum and the construction method have the advantages that SSR molecular markers are utilized for carrying out quantitative marking on the 'shenxue 108 day', and the fingerprint spectrum different from sibling species or the same series of cauliflower varieties is constructed; the applicability to identification, selling and truth-falseness discrimination of farmers for the shenxue 108 day of the cauliflower is achieved. The fingerprint spectrum and the construction method have the effects that the mastering is easy and the benefit for producers and seed buyers can be protected.

Description

technical field [0001] The invention relates to the field of molecular biology technology, in particular to a cauliflower hybrid fingerprint and a construction method thereof. Background technique [0002] my country is a country with a large population in the world, and needs a large amount of vegetables every day. Among them, cauliflower is rich in nutrition and delicious in flavor, and is one of the main vegetable types in my country. Cauliflower (commonly known as cauliflower) belongs to Brassicaceae Brassica Brassica species, native to the eastern coast of the Mediterranean Sea in Europe. In the middle of the 19th century, cauliflower was gradually widely cultivated in southern my country. At present, the annual cultivated area in the country has reached 4 million mu. However, due to serious diseases on cauliflower, especially black rot and downy mildew, the large-scale planting of cauliflower is restricted. Shanghai Rich Farm Seed Industry Co., Ltd. has been engaged...
