IV. Result
1. Introduction of genetic resource and evaluation of characteristics
From 2006 through 2001, China, the U.S. and Japan introduced 20 brand new genetic resources each year to test characteristics. By taking clinical test each year, we cross planted resource marked pregnable to secure 39 seeds, while utilizing pre-selected resource as materials to be used for development of plant strain. In doing so, we successfully grew five types of late-bolting strain and 10 early-maturing strains.
2. Test characteristics, cultivation of strains and create combinations
From 2006 through 2010, we selected strain and cross planted from generation to generation with an aim to develop early-maturing strain and late-bolting strain. We sib-cross planted to get over any potential weakness of descendants and selected seeds by group to pass them from generation to generation. In doing so, we maintained about 420 types of pollen parent and maintainers. We used late-bolting male-sterility strain Petaloid type by back-crossing with maintainer to produce seed on the mother side and thereby to produce about 70 types of A-line late-bolting strains. We also considered characteristics of both sides to create 200 to 500 combinations suitable to plant growth objective by using A-line late-bolting x C-line early-maturing strain.
3. Test F1 Combination Performance
The test is taken to evaluate 1st performance of F1 combination created by year during fall and thereby to select combination by characteristics. In doing so, Jeju test is expected to be used for test of the year, while tests taken in other regions will be used for announcement of test to be taken by region. By selecting 100 combinations out of 200 in 2006, 100 out of 511 in 2007, 110 out of 690 in 2008, 120 out of 674 in 2009 and 150 out of 1200 in 2010, we test combination capability. Ry selecting 20 to 30 combinations meeting climate conditions and regional conditions of China and India, we used them to post announcement of contact tests.
4. Suitability test by region, test for enlargement and registration of variety
As a result of developing varieties, three kinds of domestic varieties are on the route to approval for variety protection, while two kinds of varieties for export are registered as that of sale and production.
A. Develop variety for the South
The varieties developed for the South include Betarich, Sigma and Benigold. In order to replace the varieties, we complemented the selected combination performance until the second round of test to proceed with contact test. In the 3rd year, we selected late-bolting, early-maturing and early root-tip increasing complemented combination "07-3100: with o8-8638 MS CTA118 x CTC212-2-ⓧ. In the 4th year, we named the variety "Jangoh" in Feb. 2010 to seek approval for variety protection.
B. Variety developed for highland
The varieties developed for highland include Joeun, Sigma, Benigold and Nigel. In order to replace the varieties, we improve strain and combination performance until the 2nd year of test. In the 3rd year of test, we selected stable-bolting, early-maturing complemented combination "07-3025" with 08-8641 MS CTA107 x CTC212-ⓧ combination. In the 4th year, we named the variety "Gaesanhong" in Feb. 2010 to seek approval for variety protection.
c. Variety developed for winter
Varieties for Jeju include Yangmyung, Bibari, Dongha and Red Winter. In order to develop the replacement, we selected early-maturing, great root-color and high-yielding 8283 MS CTA132 x CTC272ⓧ combination whose performance was proven in the 3rd year of test. In the 4th year, we named the proven variety "Dongjanggun" to seek approval for variety protection.
D. Variety developed for China
The spread of Fl developed for China is prompted by the development of Hongyong No. 2, expanding its grip to the market for the seeds for highland, winter and fall. The spring carrot cultivated in tunnel and vinyl house include Johong 90, Hongyoung, Jo-chun-hong-kwam and Aehong. The varieties for highland include Heukjeon-gye and Nigel. SK316 is dominating the market for Bokgeon Province in China, developing the variety as that of high value added. In order to preempt the Chinese market, we developed Josaeng-gye Fl variety for spring. The testing bed was Sjandong Province, where we conducted performance test for tunnel cultivation, selecting 05-3124 combination in the 2nd year of test. By pursuing upgrade of selected seed performance with the generational succession, we selected 05-3124, advanced combination 07-7479 →08-8622→ MS CTA118 x CTC335-ⓧ combination which was verified as excellent combination of late-bolting, early-maturing. We finally named the variety "Ohseongjanggun" in Feb. 2010 to register it as that of production and sale.
E. Variety developed for India
A close look at the market Size by carrot type in India shows that kuroda and Nantes represent 58% and 42%, (Local read 5,000ha) respectively. Kuroda type is mainly cultivated from Bangalore Kolar, Udhagamandalam Ooty from March through October. Dominating varieties include Super Takii and Nantindo . Nantes-Type is mainly cultivated in Delhi from Sep. through Feb. by Early Nantes. Dominating variety is Nantindo. Local Red is cultivated only in fall in northeastern area, accounting for 50% of all land. But it is hard to identify the exact size. The test designed to develop variety for India was conducted from 2006 by Bangalore Kolar, maim market of kuroda type. We selected insect-resistant, great-enlargement 05-3022 advanced combination 06-3075→07 - 3083→08-8284 MS CT A118 x CTC258-ⓧ combination in the 3rd year of test, which we named "SuperStar" in Feb. 2001 to register it as that of sale and production.
5. Prototype production and expansion of pure variety
While three types of varieties subject to approval for variety protection and variety for India are developed to produce seeds for test, the variety for China is developed to expand pure variety. The seeds were planted in the space of 40cm x35cm as a result of conducting testing bed and characteristics. From early May, the growth started to be noticeable. In order to upgrade the quality of seed, we removed the 2nd side brance, leaving five to six cultivation areas intact. From the period when flower starts to bloom in early June, we inserted intermediary layer to spread seeds and thereby to increase test and original seeds. As a result of pregnancy of original and test seeds, male sterility was found stable. The seeds for China are being produced through Italy's company to secure export volume for the next year.
6. Search of Important disease and insects
In the 4th year of test, we reflected comprehensive view (regarding insect-induced plant disease occurring to carrot, 17 types of important carrot diseases, two types of insect-induced disease and two types of physiological diseases) to compile materials regarding growth of the varieties.
