For the purpose of developing Korean Herbalogy with the plants of Cruciferae which grow wild and is planted in Korea, the these and writings on herbalogy, from literature of successive generations, have been thoroughly investigative and the results obtained were as follows: 1. There were totaled to 23 genera and 74 species in Korea and among them medicinal plants are 13 genera, 29 species, some 39% in total but, the number of species may be added because of the similiar plants. 2. According to the oriental names which can be used for medical purpose, the medicinal plants belonging to the Cruciferae family were classified as Herba 8,Semen 7, Radix 4,Foilum,Flos 3,Rhizoma 3,Fructus 1. Thus it was noticed that Herba was the main kind. 3. According to sum of 74 species in Cruciferae family, they were classified into Arabis genera 16, Brassica, Lepidium genera 5 each. Thus it was noticed that Arabis genera was the main kind, some 23% in total. 4. According to the number of species of the origin plants about each chinese materia medicals, they were classified into SEMEN LEPIDII 10,SEMEN SINAPIS 2. Thus the origin plants was not complexed reletively. 5. According to nature and flavour of medicinal plants, they were classified into warmth, heat; 4 each, cold, cool; 7 each, balance 14. Thus it was noticed that balance is the main in nature and flavour of medicinal plants. 6. According to the Properties and Principal curative action, they were classified into Drugs for remove toxic heat with febrifugal and detoxicant drugs, to removing evil heat and resolve dampness ,Drugs for reducing intense internal Heat Digestives and Evacuants 6 each, with promote or activate blood circulation by removing blood stasis ,to clear up heat and resolve phlegm, to remove toxic heat with febrifugal and detoxicant drugs such as 6 each, to regulate the flow of vital energy, to replenish vital essence with drugs 5 each, to dispel pathogenic factors from the exterior of the body with sudorifics pungent in flavor and warming in property, to stop diseases with drugs 3 each. Thus it wasnoticed that to promote or activite blood circuration by removing blood stasis drugs was the main kind. 7. Comparing to whole medicinal plants 89 kinds, toxic durgs include minor toxin were 8 kinds, 9% of the whole.Thus toxic durgs were rare. From this result, it was revealed that the plants for medical purpose in Liliaceae was 76% of the whole, in which Bulbus was mostly abundunt and toxic plants was so rare that it will be used for clinical treatments more easily. It is considered that many experiements and clinical approaches must be continued to use Liliaceae plants widely.

The cultivation area of rapeseed (Brassica napus L.) has been increased for oil production and landscaping purpose in Korea. However, as the color of rapeseed flower is very simple, diversified flower color is necessary to improve landscape effect. Interspecific and intergeneric crosses between rapeseed (Brassica napus) and three Cruciferae crops were performed in order to grow diverse flower color of rapeseed. The silique formation rate of interspecific cross rapeseed with cabbage (B. oleracea L) was relatively high (65.8%) and higher than intergeneric cross with rapeseed and radish (Raphanus sativus L.), rapeseed and Orychophragmus, respectively. During silique developing period after artificial pollination, there were many siliques without seeds due to the failure of fertilization. The average number of seed per silique obtained from cross rapeseed and cabbage, rapeseed and radish, rapeseed and O. violaceus were 0.12, 0.4 and 0.12, respectively. The phenotypes of F1 hybrid plants from cross rapeseed and Cruciferae crops were mostly similar to maternal line, but leaf length and leaf width were increased. The interspecific cross of rapeseed and cabbage generated ivory color of flower which is the medium color of parents, and intergeneric cross of rapeseed and O. violaceus created entities with larger flowers which seems to enhance landscape effect. The fatty acid composition of most hybrid seeds intermediated of the two parents for oleic acid, linoleic acid and linolenic acid, content. Whereas hybrid of rapeseed and radish produced less erucic acid than radish parent.

A gene flow has been tested from transgenic herbicide-resistant Chinese cabbage to major crops in Cruciferae. Hybridizations were made between transgenic Basta-resistant Chinese cabbage and non-transgenic Chinese cabbage, B. napus, B. juncea and Brassicoraphanus(B. campestris × Raphanus sativus, 2n=4x=38) with honey-bee mediated fertilization. Progeny populations were selected by Basta herbicide. The F1 hybrids with pat gene were again self-pollinated or cross-pollinated with nontransgenic Chinese cabbage and rape naturally or artificially. Pod setting ratio were compared as a tentative parameter for potential gene flow. Key agronomic characters were compared among the F1 hybrid populations obtained. In the days to flowering after cold treatment, the F1 hybrids of Brassicoraphanus x B. campestris and B. napus x B. campestris(GM) were the shortest (75 days), and the GM Chinese cabbage and the F1 hybrid of B. juncea x B. campestris(GM) were 87 and 93 days, respectively. In the stem length, the F1 hybrid of Brassicoraphanus x B. campestris was the longest(175 cm), and followed by the F1 hybrid of B. napus x B. campestris(GM), the F1 hybrid of B. juncea x B. campestris(GM) in order. The naturally occurring pod setting ratios were fluctuated seriously among individual and segregation lines. Natural pod setting of the transgenic Chinese cabbage was 10 to 19 %. The F1 hybrid of B. napus x B. campestris(GM) showed the ratio of 4-11%. However, the F1 hybrids of B. juncea x B. campestris and Brassicoraphanus x B. campestris(GM) did not produced seeds. The F1 hybrids with pat gene were hybridized with nontransgenic Chinese cabbage and rape by artificial bud pollination to test potential gene flow. All cross combinations except Brassicoraphanus produced seeds and the pod setting ratios ranged from 35 to 100 percentages. Thus, the potentials of the gene flow from Chinese cabbage with pat gene to the order specise in the same gene interspecies or intergeneric species and from the F1 hybrids with pat gene to nontransgenic Chinese cabbage and rape were detected. Herbicide resistant test to the acquired seeds by natural and artificial pollinations including honey-bee mediated fertilization using the same materials is going on.
