In response to our dependent on foreign market demand of Brassica oleracea species the development cabbage seed with black rot resistance as well as high quality, high value, and market preference products that causes the problem during growing and also favorable within these region is necessary to expand the business as seed exporting market. In addition, development of resistance marker for black rot and club root while constructing high resolution molecular genetic map to create molecular breeding system for cabbage’s breeding efficiency enhancement would in the future contribute our Korean cabbage varieties towards global competitiveness and export market expansion in overseas markets.
The application and the genetic information of B.oleracea and it’s closely related Brassica species, was established by sharing information from International Brassica rapa genome projects and joint projects. It also allowed to developed varieties of markers on domestic elite breeding line using the markers obtained from genetic map and the EST and WGS(Whole Genome Sequencing) information using NGS(Next Generation Sequencing) technology of B. oleracea and B. napus. Utilizing the markers of domestic elite breeding line, molecular genetic map formed by 354 markers related to black rot resistance was created. Moreover, black rot pathology test targeting F3 individual was tested about 3 times repeatedly. By linking both result of vaccination of black rot and the genetic result map, the candidate of black rot resistance QTL regions were identified.
Within combination of club root related, about 78 of F2 individuals have been genotyped around 15,000 SNP regions following GBS(Genotyping by Sequencing) method.
Within 35 developed markers the genotyping of F2 individuals have been completed and the high-density genetic map using F2 genotyping results is still under process. The result of club root disease pathology test, for race 9 strain by repeating 2 times each while race 2 and 5 strains has each gave clean result just by performing only one time. As the genetic map completes by linking result from pathology test we could candidate the club root resistance QTL regions by each race strains.
Among many markers developed during the course of research, 184 SSR markers were used for genetic diversity analysis with worldwide 91 commercial varieties of B. oleracea, and we could obtain 16 cultivar specific markers. As the result of this experiment, various consume species could each be identified and developed for species varieties of distinctness, uniformity, stability to utilize as a useful test. We also performed research on MITE(Miniature Inverted-repeat Transposable Element) family’s identification and characterization of brassica species including cabbage. Utilizing it could further developed 36 inter-species classification polymorphic marker and 90 intra-species classification polymorphic marker.
Total 11 commercial varieties were developed for China, India and South East Asia markets. Fast Ball and Ace Ball were developed for China market and they have round head shape and green head color and extra early maturity and stronger cracking tolerance.
Forte 9 was developed for India market and its maturity is 2∼3 days earlier, more compact and greener than check varieties. Venus 11 is 5∼6 days earlier, its plant frame is more compact, greener and stronger cracking tolerance than check varieties. Smart was developed for heat tolerant, round and mid-early maturity group market in India, China and S.E. Asia. It has more compact, more stable core, stronger cracking tolerance and black rot resistance than check varieties. Joeun Ace was developed for China, India and Pakistan market. It has about one week earlier, more green color and stable head shape than check varieties and it is suitable for high density transplanting and it has more green head color, stronger transportation ability, cracking tolerance and better taste. Joeun Ace showed stronger black rot resistance than check varieties in India local trials and in vivo test.
Ellora was developed to replace 'Green Express' from Sakata, 'T-621' from Takii, Zennith and Millennium 111 from Seminis in India market. It has one week earlier than check varieties and its heat tolerance, black rot resistance and cracking tolerance level was increased up to heat tolerant type varieties. Ocean 99 was developed to replace ‘KK-Cross' from Takii and ‘KS-Cross' from Syngenta in South China market, West Bengal market in India and S.E. Asia market. Ocean 99 is 4∼5 days earlier and it has stronger heading ability under hot temperature condition, stronger cracking tolerance and stronger black resistance than check varieties. Tropic Ace was developed to replace 'KK-Cross' and Grand KK from Takii. Its head shape is more stable and stronger heading ability under hot temperature condition. Green Space was developed to replace 'New Star Cross(NSX)' from Tokita in Vietnam market. It has earlier maturity, heavier head weight, stronger cracking tolerance and black rot resistance. Verona was developed for purple cabbage market and it has 75 day maturity, round head shape and excellent internal purple color and good results in China, India and Europe market.
The segregation ratio in F2 population derived from the cross between black rot resistant line and susceptible line(C1184 x C1234) was R(resistant) : MR(intermediate) : S(susceptible) = 63 : 45 : 34( 1.9 : 1.3 : 1) and R+MR(resistant + intermediate) : S(susceptible) = 3.2 : 1. The black rot resistance of F3 population was tested during 2013 and 2014 and it was used for development of marker in Seoul National University.
The segregation ratio in F2 population derived from the cross between clubroot resistant line and susceptible line (C1220 x C1176) was R:MR:S=62:62:68(1:1:1) and the ratio of C1176 x C1220 F2 population was 159:32:3 and the ration of C1220 x C1126 F2 population was R:MR:S=147:30:21 and the ration of C1126 x C1220 F2 population was R:MR:S=67:77:53. The clubroot resistance of F3 population was tested during 2013 and 2014 and it was used for development of marker in Seoul National University.
