Recently, Cucumber mosaic virus (CMV)-P1 infection in pepper cultivation is very serious problem, which causes low marketability and yield. In this research, 56 domestic pepper cultivars including 20 PR (Phytophthora resistance) cultivars, 31 foreign pepper lines collected from USA and 112 genetic pepper resources form RDA Genebank were used for CMV-P1 resistance evaluation. Resistance evaluation was performed at 24 days and 51 days after artificial inoculation of peppers by enzyme-linked immunosorbent assay (ELISA). Among the 36 domestic cultivars 'Muhanjilju' were resistant to CMV-P1. All 20 PR cultivars and 29 foreign peppers except 'NuMex Twilight' and 'Chainese Giant' were susceptible. Among 112 pepper lines from RDA Genebank, nine pepper lines were resistant, and 17 pepper lines were moderately resistant, and 86 pepper lines were susceptible. Almost all domestic peppers on the market were highly susceptible to CMV-P1, whereas 17.2% of foreign pepper cultivars and genetic pepper lines from RDA Genebank were resistant or moderately resistant. Resistant pepper lines selected in this study can be used as genetic sources for breeding CMV-P1 resistant pepper.

Accessions of pepper germplasm were planted in the field and their characteristics were recorded. Lines introduced from Hungary were very susceptible to virus diseases and as a result poor in adaptability in domestic field condition. KC350 and KC351 which were introduced from Brazil were growing errectly and tolerant to both bacterial spot and virus diseases. KC376, an introduction from China, was bearing large fruits with tolerance to virus. Introductions from Thailand were grown and evaluated in Andong University, and major characters of them were recorded.

This study investigated flavonoid, total phenol, total flavonoid content, antioxidant and antiproliferative activity on human breast cancer cells (MCF-7, MDA-MB-231). Four varieties of Korean green peppers (KP: kkuri pepper, PP: phut pepper, CP: cheongyang pepper, OP: ohi pepper) and one foreign green pepper (JP: jalapeno) were used. The contents of luteolin, quercetin and apigenin, which are abundant flavonoids in green pepper, were the highest in KP. Also, the contents of total phenol, and total flavonoids were the highest in KP, followed by CP, JP, PP, and OP (KP: total phenol $13.29{\pm}0.45$ mg GAE/g D.W., total flavonoid $7.02{\pm}0.13$ mg QE/g D.W. In DPPH ABTS radical-scavenging activity, KP showed the most potent antioxidant activity. In the result of viability in human breast cancer cells, KP had the highest antiproliferative effect. These results suggest that green peppers have significant antioxidant activity and can be a possible candidate for treatment of breast cancer.

Sixty two lines of pepper including Korean local cultivars and introductions were planted out to the experiment farm of Kyungpook National University for seed increase, and 16 plant and fruit characters including days to flower were recorded. In days to flower, KC85(Chilgok Dongmyung) and KC116(PI308791), KC154(Cherry Sweet), and KC185(Choseongochu) were the earliest with 83 days, and KC139(Serrano chili) and KC103(PI297488) were the latest with 126 days. In fruit detachment force, KC85(Chilgok dongmyung) was the tenderest with 0.45kg and KC162(PI22444) was the toughest with 3.34kg. In powdery mildew incidence, KC10(Pimiento), KC23(PI224423), KC51(PI257044), KC56(PI257053), KC126(PI358812), KC119(PI322719), KC143(Emerald Giant), KC148(VR-2), KC163(PI224445), KC163(Papari Mild) were the least diseased. Anthracnose was least on KC39(Serrano Chili). Collection and introduction of pepper germplasm was continued. Fourteen Korean local cultivars and 25 foreign cultivars including 2 wild species were additionally collected or introduced.
