Intergeneric crosses over 34 cross combinations between genus Brassica and Raphanus were made. Ovules taken out of crossed were cultured on MS media supplemented with 1.0 mg/L GA and BA. Germination of embryo from ovule culture was not influenced by BA and GA in medium but by parental characters in its cross combination. Use of Raphanus sativus cv. Daibyosobudore and Jungkukcheongpi showed low embryo germination when they were used as male part. Cross combination with Brassica juncea as male parent showed slightly increased germination compared to other cross. These results indicated that embryo germination in ovule culture was not much influenced by casein hydrolysate, malt extract, BA, kinetin and glutamine in the medium, but parents in combination were key factor for increasing embryo germination.

Recently, as consumers' interest and importance in health care have significantly increased, they prefer natural and organic foods that do not use chemical pesticides. Since sprout vegetables effectively promote health and prevent diseases such as cancer and cardiovascular disease, the consumption of sprout vegetables, a highly functional and safe food, has been increased significantly. This study aimed to investigate the effect of light on the growth and bioactive compounds of seven different sprout vegetables. After sowing the seeds of various sprout vegetables (kale, Chinese kale, broccoli, red cabbage, alfalfa, red radish, and radish), the sprouts were cultivated under light conditions (20℃, RGB 6:1:3, 130 μmol·m^-2·s^-1, 12 hours photoperiod) and dark condition for 7 days. Sprouts samples were taken at 1-day intervals from 4 to 7 days after treatment. The fresh weight, dry weight, plant height, total phenol content, and antioxidant capacity were measured. Brassica species (kale, Chinese kale, broccoli, red cabbage) and Medicago species (alfalfa) had significantly higher fresh weight values under dark conditions, while the content of bioactive compounds was increased considerably under light conditions. In contrast, the fresh weight of Raphanus genus (red radish, radish) significantly increased under the light condition, but the antioxidant phenolic compounds were significantly higher under the dark state. A negative correlation was observed between the growth and secondary metabolites in various sprout vegetables. This study confirmed the effect of light and dark conditions on different sprout vegetables' growth and nutritional value and emphasizes the importance of harvest time in producing high-quality sprout vegetables.

Two sinapic acid esters were isolated from the methanol extract of Raphani Semen. The structures were elucidated on the basis of spectroscopic methods $(^1H-NMR,\;^{13}C-NMR,\;HMQC,\;^1H-^1H\;COSY\;and\;HMBC)$ and were identified as methyl sinapate (1) and ${\beta}-D-(3-O- sinapoyl)fructofuranosyl-{\alpha}-D-(6-O-sinapoyl)glucopyranoside$ (2). Compound 1 was first isolated from the genus of Raphanus.
