Genetic differences among nine land races of Korean ginseng (Panax ginseng C. A. Meyer) were examined using RAPD markers. Land races of Korean ginseng were collected from nine regions in Korea: Cheongwon, Guesan, Geumsan, Namwon, Pochun, Yangju, Yeoncheon, Yeongju. Out of 48 RAPD primers tested, 5 primers (OPA 7, OPA 13, URP 2, URP 3 and UBC 3) produced remarkable bands which showing polymorphisms among evaluated collections. Lower levels of genetic diversity were in detected same land races than among other land races. Genetic differences within and among land races indicate heterogeneity. These results indicate that cultivated ginseng in Korea is heterogeneous. Genetic similarity matrices of RAPD profiles were generated via coefficients of variation and the data were processed by the cluster analysis (UPGMA). When 90 collections were evaluated using selected 5 primers, those were clustered to 5 and 3 subgroups. These differences in genetic variation between land races of Korean ginseng implied the potential source for further breeding of Korean ginseng.

The experiment was carried out to study the variations and geographical distribution of $\beta$-amylase isozyme by isoelectric focusing (IEF) within Korean, Chinese and Japanese soybean land races. In pH 3-10 gel of IEF, the amylase of soybean accessions was separated into low pI group isozymes (TEX>${$Sp_1$}^b$) and high pI group isozymes(${$Sp_1$}^a$). In pH4-6.5 gel, isoelectric points were at 5.07, 5.15, 5.25, 5.40, and 5.94, and h, j, and k bands also were found. The distribution of Sp$_1$$^{a}$ allele (high pI type) was 29.3% in soybean accessions from Korea, 10.1 % in those from China, and 6.9% in Japanese accessions. The percentage of ${$Sp_1$}^a$) allele was the highest in soybean accessions from Kyungsang province (35 %) in Korea, then central China (32 %) in China, and Honshu (10%) in Japan.

One thousand and seven hundreds and six soybean land reces and 103 wild soybeans of Korea, and 167 cultivars and 71 wild soybeans of exotic were analyzed using polyacrylamide gel electrophoresis to study the distribution of trypsin inhibitor phenotypes. The four ti/ti lines were observed only in Korean native land races. The Ti$\^$*/a allele of cultivar was found to be the highest in Chinese soybean (0,9888) than in Korean soybean(0.8347) and Japanese soybean (0.5954). The heterozygosity of typsin inhibitor in Korean lines occured in relatively high ratio, The percentages of heterozygosity of the Korean land race and wild soybean are 3.6% (N=61) and 9.7%(N=10), respectively.

The paper evaluated the behavior of in vitro culture responses from a diverse set of Indica rice (Oryza sativa L.) genotypes. Significant differences were found in embryogenic callus induction frequency, callus growth and plant regeneration frequency when mature embryos of 11 cultivars, breeding lines and land races were compared. Genotype as well as plant growth regulator influenced the plant regeneration frequency. Callus induction frequency was not correlated with callus growth as well as plant regeneration frequency. The regenerated plants could grow to normal, fertile plants after they were successfully established in soil.

In Faulkner's many works, most Mulattoes are represented as tragic characters who feel confused with their racial identity and are sacrificed by the Southern racism in the end. However, in Go Down, Moses Lucas Beauchamp is an exceptional mulatto in that he survives the Southern racism and achieves some dignity as a human. It is because he maintains the relationship with his family and environment as a skilled farmer. Although Southerners idealized their lives in plantations as nature-friendly and ecological way of life, plantation owners had little direct relationship with land as plantations were cultivated by black slaves' labor. Therefore, white landowners had little knowledge about cultivation and ecological awareness. Although Lucas Beauchamp is criticized as he has the strong will to power and patriarchal attitude, it is partly caused from endeavor to overcome the suppression as a black male whose masculinity is denied in the Southern society. In spite of his limitation, he shows the possibility to escape from the curse prevailing in the South, which abuses land and other races through the relationship with others and land. He has positive aspects in that he has genuine relationship with land and others and takes his responsibility for others, searching the most suitable way to survive as a black.

Lines bred for resistance to Phytophthora capsici by incorporation of resistance to P. capsici in PI201234 or CM334 into 'Subi' and 'Chilseong', land races in Youngyang, and 'Punggak', a land race in Cheongdo in Gyeungbuk province, and lines bred for fortification of one of them above with resistance to viral complex, and tolerant selections from another landrace collection from Punggak (KC268) were evaluated for resistance to P. capsici by inoculation at seedling stage. Almost all the breeding lines showed high level of resistance to P. capsid and selections from KC268 showed tolerance or moderate resistance to P. capsid. The selected plants were grown in a net cage in an outdoor nursery for seed production. Utilization of the lines in breeding was discussed.

528 Korean land races of barley were examined for IS agronomic traits to determine if any preferential trait associations with early heading and winter hardiness existed in this collection. Eight traits were non-randomly associated with the 1977～'78 cold damage levels, and seven traits were non-randomly associated with heading date. No early heading, least-cold-damaged land race lines were found. However the least-cold-damaged class preferentially associated with mid-early heading land race lines. Ten traits were preferentially associated with the mid-early heading, least-cold-damaged class. The utilization of these associations should increase the probability that genes for winter hardiness will be preserved in the mid-early heading selections from this collection.
