Perilla frutescens var. crispa has a unique aroma, purple leaves, and is similar in appearance to perilla. It is an annual herbaceous plant belonging to the Lamiaceae family, in addition it is known to have various pharmacological effects. In 1995, 200 Gy of gamma rays were irradiated to ‘Chookyoupjaso’ landrace seeds, and 6 candidate mutant lines with optimal agronomic traits were selected in the first round. Of them, one of mutant lines which had an increased isoegomaketone content and an anti-inflammatory component, were selected and cultivated. Subsequently, the variety protection right was registered in 2022 under the varietal name 'Antisperilll'. The main characteristics of 'Antisperilll' were that the leaf color changed from purple to green, the seed color from brown to gray, and the 1,000 seed weight was 3.29 g, which was approximately 1.7 times heavier than the original wild type (1.94 g). The isoegomaketone content, which exhibits anti-inflammatory effects, was increased and is expected to be used as a new health food and raw material to improve inflammatory diseases (Registration No. 8812).

In order to investigate salt-tolerant sorghum germplasms that can grow in saline soil from newly reclaimed land, we measured a well-established germination rate, and growth characteristics including leaf number, height, and root length in salt-treatment conditions (0.3, 0.6, 0.8, and 1.2%) and untreated control. The highly salt-tolerant sorghum line was confirmed using PCA (principal component analysis) analysis and fuzzy comprehensive evaluation method. Germination rate gradually decreased at doses higher than 0.3%, but the germination rates reached about 70% in IT124115, IS1041, Dansusu4ho, and Dansusu2ho germplasms. At 0.6% salt-treatment condition, the germination rates ranged from 35% to 100%. Only seven germplasms (IT103274, IT101381, IT104110, Dansusu4ho, IS20740, IS22720, and IS27887) had germination rates exceeding 50% at 0.8% salt-treatment. At 1.2% salt-treatment IT124115, IT028385, and IS1041 withered. The total number of leaves decreased similarly for both germplasms at salt levels below 0.6%, and sweet sorghum leaf count was more susceptible than grain sorghum at doses higher than 0.8%. In addition, the height of both germplasms was severely reduced even at low salt concentrations, whereas grain sorghum exhibited a greater sensitivity to salinity stress in terms of root length, while sweet sorghum had longer roots at low concentrations when compared with the untreated control. PCA analysis and fuzzy comprehensive evaluation showed that 29 sorghum accessions could be divided into 3 groups based on the germination rate and morphological traits. Especially, sweet sorghum accessions showed a different pattern of PCA plot when compared with the grain sorghum, and salt tolerance could be divided into 5 groups using MFV in terms of their traits. Taken together, the results from this work will contribute to the development of domestic agriculture utilizing marginal land such as reclaimed land by selecting elite sorghum germplasms that have a high salt tolerance and capacity.

Kenaf (Hibiscus cannabinus L.) is an annual herbaceous crop of the Malvaceae family. Recently, kenaf is being used in many diversified applications such as pulp, animal feed, bioplastics and cellulosic biofuel etc. A new cultivar 'Jangdae' was developed by mutation breeding using irradiated with 300 Gy gamma-rays. Jangdae has a few distinguishable characteristics such as early flowering, high seed yield and palmate leaf, compared to wild type (Jinju). The fresh matter (FM) and dry matter (DM) yield of Jangdae are similar to those of Jinju, their seed yield (833.3 kg/ha) is approximately 4 times higher than that of Jinju. In addition, the FM and DM yield of Jangdae are 40% higher than those of early-maturing cultivar (C11). We performed the nutritive value of four kenaf cultivars (Jangdae, Jinju, C11 and Hongma300) at 100 day after seeding. The crude protein content of Jangdae, Jinju, C11 and Honma300 were 10.5, 11.0, 9.4 and 10.6%, respectively. The crude fiber, neutral detergent fiber and acid detergent fiber contents were no significant difference among the cultivars. Jangdae, which afforded both a high biomass and seed yield in South Korea, may be useful as potential source of feed and industrial materials.
