Climate change caused by global warming, is predicted to have severe consequences for ecosystems and economic sectors. In the agricultural industry, it is predicted that there will be decreased crop yields resulting from shifting planting seasons, as well as higher temperature and water stress which significantly reduce crop productivity. Kimchi cabbage, a cold-loving plant, is particularly vulnerable to high-temperature stress which can lead to stunted growth, increased susceptibility to pests like soft rot, reduced yield, and lower quality that will negatively impact the Kimchi cabbage market. Kimchi cabbage can be cultivated in highland regions with low summer temperatures and reduced pest occurrence, but rising temperatures and water stress are expected to increase pest pressure, resulting in a rapid decrease in the potential cultivation area of Kimchi cabbage. Currently, research is being conducted around the world to identify physiological mechanisms of heat tolerance at the molecular level, selection of heat-tolerant material, and studies on cellular responses of plants under high-temperature conditions. Despite numerous studies on physiological and biochemical responses of Brassica crops to high temperatures, there is a need to develop heat-tolerant Kimchi cabbage cultivars that can adapt to rapidly changing climates, new strategies for pest control under high-temperature conditions, and mitigation measures to ensure stable cultivation and production.

‘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.
