This study was done to obtain their morphological traits to analyse genetic diversity and intraspecific relationship of 47 Polygonatum species collected from Gyeongnam province. Plant height was the highest in P. thunbergii but the shortest in P. involucratum. Growth habit and its colors were classified to 3 groups, respectively. Leaf shapes were sorted to 5 groups including lanceolate with petiole or none, petiole colors were done to 3 groups including a species having dark green leaves of purple colored margin. Flower shapes were divided as 3 groups of urceolate, tubular and gourd shapes, and its colors were white, greenish white and light green, especially light green in a species with gourd shape. Filament shapes were two types of flatness and cylinder. Peduncle color and bract attached below it showed 4 types, respectively. Fruit shapes were sorted to 3 groups. In 100-fruit weights P. ordoratum var. pluriflorum showed the greatest but P. involucratum did the least. Two species were completely resistant to leaf brightness although 7 species showed less than 7 % infection rates. Rhizome yields ranged from 4.4 g to 94.8 g per plant, showing their significant variation. In correlation analysis between 9 major characters, rhizome yield per plant was positively correlated with plant height, stalk diameter, leaf number, leaf length and width, and rhizome diameter but leaf brightness was negatively done with plant height, stalk diameter, leaf number and length, 100-seed weight, rhizome yield per plan and rhizome diameter.

Germination ratio on the 300 collected genetic resources showed 80 to 100 percentage, but those of some accessions were very low as below 30 percentage. Early growth phase of most of these lines were very poor while some collected lines were very vigor. Range of stem height showed from 150 to 199cm, but that of some accessions showed below 100cm as five percentage and some of them was over 250cm as eight percentage. Number of tillers per plant appeared less one but some collected lines have two to three tillers per plant. In days to tasseling, some accessions showed more four per plant. Ear length of these accession showed above 60 percentage as 11 to 15cm, while that of some collected lines showed over 10 percentage as 16 to 20cm.

An investigation was made to find regional differences and seed characteristics of buckwheats collected from 36 areas in Chungnam province in 1984, and the results obtained are summarized as follows; 1. Grain types of the collected buckwheats were classified as winged, semi-winged and common types. All collections were on the average composed of 50.1 % of common grain types, 26.8 % of semi-winged type and 23.1 % of winged types, respectively. However, there was a great regional difference in components of each grain type among collections. 2. The mean 1000 grain weight was 24.9 gr. The regional differences in 1000 grain weight showed that a collection (collection no. 30) from Susan was 17.4 gr and a collection (collection. no. 16) from Suchon was 31.9 gr. There wasn't any significant relationship between grain types component and 1000 grain weight. 3. Germination of seeds was accelerated as temperature goes up from $5^{\circ}C$ to $30^{\circ}C$. However, interesting germination pattern was observed. That is, seeds from Suchon (collection no. 16), Hongsung (collection no. 23), Cheonweon(collection no. 35), and Yesan (collection no. 27) showed abrupt decrease of germination rate at the temperature of $15^{\circ}C$. The seeds collected from Suchon (collection no. 29), Dangjin (collection no. 32) and from Chungyang (collection no. 21) showed decrease of germination rate at $25^{\circ}C$. These seeds showed, however, the increase of germination percentage at temperature higher than $15^{\circ}C$ and $25^{\circ}C$, respectively. The germination rate for the most collections at $5^{\circ}C$ was less than 10%. However, seeds from Asan (collection no. 33) and Daeduk (collection no. 3) showed 20% and 30% of germination rate at $5^{\circ}C$, respectively. 4. Color of seed coat could be classified into two maj or colors, dark and dark brown. Based on the seed coat color and grain types, all the collections could be classified into the following six categories: winged-black, semi-winged-black, common-black, winged-dark brown, semi-winged dark brown and common-dark brown. The different light absorption rate was found within the UV light zone (190-390 nm) depending upon the two different major seed coat color.

The knowledge of native wild mushrooms traditionally using in Jeju Island, that have specific native environment and various biodiversity, was investigated. From Jeju and Seogwipo cities including 7 provinces 4 locals, so total 50 villages, data was collected in the entire area and voice of the 93 elderly people between the age of fifty and ninety were recorded. As a result, total 23 native wild mushrooms were used in which 2 species were poisonous mushrooms, 7 species were medicinal mushrooms, 2 species was used for folk religion, 2 species were not used for living but for attention and 12 species were edible mushrooms. Also, a total of 267 cases of traditional knowledge was collected, in which 197 cases were about edible mushrooms for 12 species, 43 cases were about poisonous mushrooms for 2 species, 16 cases were about medicinal mushrooms for 7 species. Interestingly, the fortune for agriculture was told depending on spore mass release of Cyathus stercoreus which grows in animal feces and compost. It is considered as the distinctive traditional knowledge of Jeju Island.

Anthocyanin contents of black soybean were analyzed for development of superior breeding lines with high anthocyanin contents. Total 292 genotypes of black soybean collected through the whole country were analyzed by HPLC in which C3G (Cyanidin-3-Glucoside), D3G (Delphinidin-3-glucoside), and Pt3G (Petunidin-3-Glucoside) were detected main anthocyanin pigments and each pigment contents were significantly different according to genotypes. C3G content showed the highest value in all materials and its variation was also wide, whereas D3G and Pt3G were not detected in 4 and 24 genotypes. Mean value of C3G, D3G, and Pt3G contents were $8.05{\pm}4.225$, $1.80{\pm}0.854$, and $1.15{\pm}0.781\;mg/g$, respectively. In case collected sites, genotypes collected in Chungnam region were higher the anthocyanin contents than other collections, which was $13.75{\pm}3.861\;mg/g$. It might be concluded that it takes more than 36 days for anthocyanin accumulation since beginning of seed-coat pigments formation, in that case it showed $13.09{\pm}4.190\;mg/g.$. Also total anthocyanin contents were present higher concentration in seed coat as maturation period was longer from flowering stage.

Morphological characteristics of Cordyceps species and its allies collected in Korea were clarified. Through the survey conducted from June 1999 to October 2002 in 19 mountains in Korea, 667 samples of entomogenous fungi were collected. Cordyceps and its allies of 17 species of 5 genera were identified as Cordyceps gracilioides, C. japonica, C. longissima, C. martialis, C. militaris, C. myrmecophila, C. nutans, C. pruinosa, C. sphecocephala, C. tricentri, Hirsutella nutans, Paecilomyces cicadae, P. farinosus, P. tenuipes, Paecilomyces sp., Shimizuomyces paradoxa, Tilachlidiopsis nigra. The fungi with insect hosts have been collected mainly in the place of shade or mosses near brooks and streams that had high humidity. Overall the frequenct of fungal infection in natural ecosystem was relatively low as few as 10 collections per each species. However, many species were found in terms of the few number of colleciton sites with seasonal limitations. Occurrence of the fungi in Jeju island remote from inland of the Korean peninsula were diverse in their species due to the varied weather of vertical distribution following the altitude. Three most common species were C. nutans, P. tenuipes and C. militaris, mainly found early in August when the relative humidity and temperature were high, of which C. nutans occupied the highest frequency consisting of 65% in total collections. Neither variation in ascomata arrangement in stromata nor developement of secondary spores was recognizable, while the number, shape and colour of stromata varied with insect hosts and weather conditions.
