Physicochemical and antimicrobial activities of 12 different garlic cultivars were investigated. Width and weight of California late cultivar (60.44mm, 53.73g) was the biggest and heaviest but Changyoung cultivar (44.04mm, 25.15g) was the smallest and lightest among the variety of garlic. The range of L, a and b color characteristics of garlic surface from different variety were 84.13~90.56, -1.10~0.77 and 18.24~26.61, respectively. Shear force was the lowest in California early, but 94-12-2 cultivar ($4211.35cm/kg^2$) was higher than another cultivars. Soluble solid range was 6.40~11.33 %brix, and Changyoung cultivar was the highest than the others, significantly. pH of garlics from different cultivar were 5.57~6.53. Total thiosulfinate content of California late cultivar (146.05mM/g) was higher, but Italy cultivar (93.23mM/g) was lower than the others. Total pyruvate content was the highest in Yugo cultivar ($162.50{\mu}M/g$) and the lowest in California early cultivar ($147.41{\mu}M/g$).

We have studied the DNA of Allium sativum L. with respect to highly repetitive sequences. Fast reassociated DNA fragments expected to be highly repetitive sequences based on $C_{o}t$ curve were isolated and characterized. Their copy numbers were approximately $10^{5}~10^{7}$ per haploid genome. Nucleotide sequences analysis of six candidates reveals that their G/C content were low, 25-40% and typical patterns of repeating sequences exist. Repeat sequences were used as probes to access restriction fragment length polymorphism (RFLP) of genomic DNAs of four local clones, Tanyang, Mungyong, So san, and Uisong. The hybridization pattern were very similar among these four local clones.clones.

This study was conducted to clarify of relationship with major physiological characters and RAPD patterns of garlic(Allium sativum L.) germplasm collected from the worldwide using randomly amplified polymorphic DNA(RAPD) analysis. Eighty-four garlic accessions were classified into ten varietal groups by physiological characters with the single linkage clustering based on Q correlations. The majority was early maturing varieties collected from East-Asia, late maturing varieties were Europe. RAPD marker, $WE61_{1,630}$ was amplified with late maturing varieties and high correlation have shown, though three accessions weren't amplified. Clove undifferentiation and secondary growth had mainly occur accessions collected from Europe, but hadn't shown perfect linkage to RAPD. RAPD marker, $WF70_{1,400}$ appeared in bolting garlic and $WF64_{1,400}$ appeared only in fertile garlic. Unknown garlic amplified in $WF64_{1,400}$ might be fertile garlic, because of their collection site were from Central-Asia.

Occurrence of rust on 2 representative garlic cultivars Daeseo and N므애 in major cultivating regions of Goheung-gun, Jeonnam and Namhae-gun, Gyeongnam was investigated during 1998-1999. Rust disease severities of garlic ranging from 1.2 to 85.8 were quite different according to the investigating years and cultivars. Relatively high rust severities of garlic were observed in 1998 compared with 1999. This might be due to remarkably frequent rainfalls and high humidities during the growing seasons of garlic in 1998. Rust occurred severely on cultivar Daeseo but not on cultivar Namdo. This shows quite different susceptibility or resistance to rust among the cultivars of garlic. Increase of rust severities resulted in remarkable decrease in yields of garlic. It is assumed that rust might cause serious damages in the cultivation of garlic.

This study was performed to investigate the physiological activity of Hongsan garlic and Hansan garlic, which were registered in the plant breeders' right in 2016. The content of mineral components, except sodium and sulfur ingredients, was found to be high in Hansan garlic. In addition, organic sulfur components were high in Hansan garlic. Moreover, the total soluble solid content, reducing sugar content, and alpha glucosidase inhibitory activity were high in Hansan garlic. Acidity, pH, total phenol, and flavonoid content were high in Hongsan garlic. Both varieties showed higher inhibitory activity to gram-positive bacteria than to gram-negative bacteria. The antimicrobial activity of Hongsan garlic was slightly higher than that of Hansan garlic. These results are expected to provide useful information to farmers who grow the above garlic varieties.

Antimicrobial activity of garlic extracts of four local cultivars (Namdo, Goheung, Danyang and garlic imported from China) against several plant pathogenic bacteria and fungi was investigated. The garlic extracts exhibited marked in vitro antimicrobial activities against the Gram-positive and -negative bacteria as well as fungal pathogens. Of the four cultivars, two cultivars (Namdo and garlic imported from China) showed relatively good antimicrobial activities. Gram-positive bacteria, Clavibater michiganensis was most sensitive, whereas Burkholderia cepacia was the strong resistant towards garlic extracts. Results from the planta bioassays under greenhouse conditions indicated that garlic extracts significantly reduced the cucumber powdery mildew disease showing control value 59.7-61.9% compared with the nontreated controls.

Although the chemical compositions and biological characteristics of some species of garlic have been investigated, data on Koara garlic are currently lacking. In order to investigate the major compounds and antimicrobial activity of Koara garlic, which was registered as a cultivar in 2012, it was cultivated in Seogwipo, Damyang, and Namhae. Analysis of the chemical composition of the cultivated garlic showed that the alliin, pyruvate contents, and antimicrobial activity were high in garlic grown in Seogwipo ($9.44{\pm}0.28mg/g$, $127.52{\pm}5.50{\mu}M/g$, and 0.31-1.25%, respectively). The total phenol content and reducing sugar contents were abundant in garlic grown in Namhae ($82.23{\pm}0.00g\;GAE/100g$ and $28.59{\pm}0.54mg\;GE/g$, respectively), and the total flavonoid content was high in garlic grown in Damyang ($22.41{\pm}0.77g\;QE/100g$). Although garlics grown in different cultivation areas had different chemical compositions, major compound contents and biological activities of Koara garlic were similar to those of other garlic varieties reported so far. These data will be useful for local farmers, distributors, and consumers.

Mycelial growth and days required for sclerotial formation(DRSF) in vitro, and disease incidence of infected plants in the field were investigated to evaluate disease resistance of nine garlic cultivars against two species of Sclerotium causing garlic white rot. There were differences among mycelial growth and sclerotial formation of two white rot pathogens on different garlic cultivars in vitro. Mycelial growth showed the highest level on the clove of 'Daeseo'. Sclerotia of two white rot pathogen were formed the earliest on the clove of 'Kodang' and the latest on the clove of 'Namdo'. In field trial all of nine garlic cultivars were highly susceptible to Sclerotium cepivorum and cold-type garlics were less susceptible than warm-type garlics. Meanwhile garlic cultivars used showed differences among resistant responses to Sclerotium sp., forming large sclerotia. All of warm-type garlics showed highly susceptible response, but three cold-type garlics, 'Seosan', 'Danyang' and 'Yechon' showed moderate resistant response and 'Euisung' showed resistant response. To evaluate cultivar resistance of garlics quantitatively disease progress curve was transformed as linear regression equation. Among the intercept (early disease incidence) and the slope (disease infection rate) obtained from the transformed equation, final disease incidence, and area under disease progress curve(AUDPC), AUDPC was the most effective to evaluate disease resistance of garlics to both of white rot pathogens. There was little correlation between mycelial growth and sclerotial formation on garlic cloves in vitro, and epidemiological parameters (early disease incidence, final disease incidence, disease infection rate, AUDPC) obtained from the field trial. Mycelial growth of S. cepivorum was positively correlated with final disease incidence and disease infection rate obtained from the field trial, meanwhile DRSF was negatively correlated with the epidemiological parameters.

In this study, the quality characteristics of the representative domestic garlic varieties in Korea (Namdo, Daeseo, Hongsan, and Uiseong garlic) were compared and their changes according to the aging process of black garlic were investigated. Each garlic sample was aged for 15 days according to the manufacturing process of black garlic. The total phenolic compound contents were 85.2-109.7 mg GAE/100 g in raw garlic samples, which increased with the aging period, and Hongsan garlic showed the highest content in both raw and aged black garlic. The content of alliin was 848.3-1,087.5 mg/100 g in raw garlic samples, and it decreased significantly on the 5th day (7.3-20.6 mg/100 g) in aged garlic. The contents of GSAC (γ-glutamyl-S-allyl-cysteine) and GS1PC (γ-glutamyl-S-1-propenyl-l-cysteine) in raw garlic samples were 202.1-541.0 mg/100 g and 311.1-474.3 mg/100 g, respectively, but gradually decreased during the aging process. On the other hand, the SAC (S-allyl-cysteine) and S1PC (S-1-propenyll-cysteine) contents of raw garlic were very low in all four varieties, but they were highest on the 5th day of aging and tended to decrease thereafter. On the 5th day of aging, the SAC content of Namdo garlic (208.0 mg/100 g) was highest (p<0.05), and S1PC content was significantly higher in Uiseong garlic (66.2 mg/100 g) than the others.
