  • It is necessary to evaluate the location suitability of protected horticulture facilities to guide and/or to plan new protected horticulture facilities in rural areas. For objective and systematic evaluation of location suitability of protected horticulture, three different evaluation models were constructed based on grading, proportion, and analytic hierarchy process(AHP). The models were used to evaluated the suitability of protected horticulture in three selected regions; suburban, plain, and mountainous. The results showed that there were significant differences in evaluation results of each model among the three regions.

  • This study used a modified cetyltrimethylammonium bromide (CTAB) method to efficiently extract DNA from the plant pathogenic fungus Cercospora sojina. Total DNA yield obtained by this method was approximately 1 mg/g of mycelia (fresh weight), and the mean ratio of A260/A280 and A260/A230 were 2.04 and 2.1, respectively. The results of random amplified polymorphic DNA (RAPD) analysis, digestion with restriction enzymes, and Southern hybridization indicated that polysaccharides were effectively removed by this method, and the resulting DNA was sufficient for use in subsequent molecular analysis.

  • A total of 19 selections derived from 4 sources of peppers with resistance to gray leaf spot (KC43, KC47, KC220, and KC319) were tested for their nuclear genotype of the gene conferring the ability to restore the cytoplasmic male sterility. All the selections derived from KC220 and KC319 were maintainers with a genotype of Nrfrf, while all the selections from KC43 and KC47were restorers with a genotype of N(S)RfRf.

  • A new powdery mildew resistant squash (Cucurbita moschata Duch.) 'Miso' was bred from a cross between powdery mildew resistant true variety 'Sangol' and powdery mildew susceptible inbred line 'Seoulmadi' at National Institute of Horticultural & Herbal Science (NIHHS). The 'Miso' variety was vigorous and highly resistant to powdery mildew. It showed white green fruit color. The variety yielded 21.3MT/ha which is 52% more than control variety.
