A new rapeseed (Brassica napus L.) variety ‘Jungmo 7003’ is with early flowering and disease tolerance, which has white petals. ‘Jungmo 7003’ was developed from the cross between ‘Tower’ as female parent and ‘AB130’ as male parent in 1983. The selection for advanced lines with white flower had been done by the pedigree method. A promising line, ‘83025-B-1-1-2’, was selected and designated as the name of ‘Mokpo113’. It had good results from regional adaptation yield trials at four locations for two years from 2013 to 2014 and was released as the name of ‘Jungmo 7003’. ‘Jungmo 7003’ has light-green and middle parted leaf, light-green stem and black seed coat. Since, the prominent very special trait of ‘Jungmo 7003’is white flower, it can be used for landscaping purposes created farm-art images. The flowering date of ‘Jungmo 7003’ was 16^th April and ripening date was 5^th June.

The oil content of ‘Jungmo 7003’ was 43.8%. In fatty acid composition of ‘Jungmo 7003’, oleic acid content is 68.4%, which is 1.2% higher than ‘Hanlayuchae'. ‘Jungmo 7003’ will be adaptable to southwestern area including Jeonllanam-do, Jeollabuk-do and Gyeongsangnam-do and Jeju island of Korea.

Male sterile line in onion is essential to the development of hybrid varieties. Onion male sterile line 'Wonye30005' was developed by Bioenergy Crop Research Center, NICS, RDA in South Korea in 2010. Lodging date of 'Wonye30005' is May 15^th and it belongs to the early maturing type in Korea. We found the male sterile plants in ‘Hamasodachi’, early maturing open-pollinated variety, and the male-sterile plants were cross-pollinated with male fertile line, ‘M330’, the population of F₁ showed 100% male sterility and the F1 plants were subsequently backcrossed for five generations. 'Wonye30005' was numbered as ‘MMS77’ in 2009 and the corresponding male parent is called MMSB77. 'Wonye30005' has round bulb shape (Bulb index, 97), cold resistance, and excellent storage quality and average bulb weight is 253g. Flowering date is May 25^th and flower bud size is 84 mm in full bloom. The number and length of flower stalks per bulb are 4 and 134 cm, respectively. 'Wonye30005' has been filed in Korea Seed and Variety Service in 2010. Overall, 'Wonye30005' is promising male sterile line for early maturing type hybrid seed production and breeding program.

A new rapeseed (Brassica napus L.) F₁ hybrid ‘Haean’ was crossed between ‘Mokpo-CGMS’, male sterile line and ‘8516-B-5-6-1-2’, restore line for the adaptation of paddy land culture with early maturing, disease resistant and lodging tolerance in 2008. Yield trials were conducted from 2009 to 2010 in Muan, and regional adaptation trials were examined from 2011 to 2013 in four regions. ‘Haean’ has dark green, cleft and parted leaf, light yellowish flower, and black seed color. The maturation date of ‘Haean’ is 4^th June, 4 days earlier than ‘Sunmang’. In the regional adaptation trials, average yield of ‘Haean’ was 272 kg/10a, which was 6% higher than ‘Sunmang’. Seed oil content of ‘Haean’ was 44.2%. In fatty acid composition, oleic acid content is 69.8%, which is 2.5% higher than ‘Sunmang’. Total glucosinolates content was 1.84 mg/g. ‘Haean’ has characteristics of disease resistant and lodging tolerance, this variety can be cultured at paddy lands in southwestern area including Jeonnam, Jeonbuk and Kyongnam provinces and Cheju island of Korea.

‘Jungmo 7002’ is a intermediate parent of rapeseed (Brassica napus L.) with flowering uniformity and lodging tolerance for the scenery and oil production. ‘Jungmo 7002’ was developed from the cross between ‘RS10//Erra/Tower’ as female parent and ‘RS10’ as male parent in 1984. A promising line, ‘84013-B-6-3-3-6’, was selected and designated as the name of ‘Mokpo116’. It was prominent and had good result from regional adaptation yield trials (RYT) for three years from 2011 to 2013 and was released as the name of ‘Jungmo 7002’. ‘Jungmo 7002’ has middle parted and dark-green leaf, Brownish-green stem, yellowish flower and black seed coat. The flowering date of ‘Jungmo 7002’ was 16th April and ripening date was 9th June. The yield of ‘Jungmo 7002’ was 247 kg/10a, which was 19% higher than ‘Hanlayuchae’ in regional adaptation trials. This intermediate parent showed high resistance to lodging tolerance. The oil content of ‘Jungmo 7002’ was 44.3%. In fatty acid composition of ‘Jungmo 7002’ , oleic acid content is 70.8%, which is 3.3% higher than ‘Hanlayuchae’. And ‘Jungmo 7002’ has no erucic acid. ‘Jungmo 7002’ will be adaptable to southwestern area including Jeonllanam-do, Jeollabuk-do and Gyeongsangnam-do and Jeju island of Korea.

The production of hybrid onion (A. cepa L.) seed is economically feasible using systems of cytoplasmic male sterility (CMS). Therefore, male sterile (A-line) and maintainer (B-line) is essential to development of F1 hybrids. Male sterile line Wonye30006’ was developed by Bioenergy Crop Research Center, National Institute of Crop Science, RDA in South Korea in 2010. The first cross for introduction of CMS was conducted in 2000. Male-sterile parents which were selected from ‘F2-6’ breeding lines were pollinated with male fertile line ‘HMB’ (inbred line). The fertility test was conducted in 2002 and maintainer line ‘Mo2005’ was selected. The proportion of male-sterility plants of F1 population was 100% for subsequent four backcross generations. ‘Wonye30006’ was named ‘MMS66’ in 2009 and the corresponding male parent was called ‘MMSB66’. As an mid-late maturing type, lodging date is around May 25^th. ‘Wonye30006’ has round bulb and the average bulb weight is 184 g. Plant height and stem diameter are 56 cm and 12.4 mm, respectively. Number and the length of flower stalks per mother bulb are 122 cm and 6, respectively. Flowering date is June 4th and flower bud size is 81.2 mm. Wonye30006 will be used for development of F1 hybrids in breeding program. (no. 4674)

The flowering and ripening period of ‘Jungmo 7001’ were 3 days earlier than check variety 'Hanlayuchae'. The average flower size of ‘Jungmo 7001’ was significantly greater than flowers of 'Hanlayuchae'. The average seed yield of ‘Jungmo 7001’ was higher compared with 'Hanlayuchae' in local adaptability test. Total oil content of ‘Jungmo 7001’ was 44.4%.
