:Watermelon (Citrullus lanatus) is an important vegetable crop in the world and contains various health promoting compounds including many antioxidants such as lycopene and beta-carotene. Genetic diversity of cultivated watermelon is very narrow, which is one of major factors limiting the improvement of watermelon breeding program. Gummy stem blight (Didymella bryoniae (Auersw.)) is one of the most destructive diseases and causes crown blight, defoliation and fruit rot, resulting in severe production loss in watermelon. Single nucleotide polymorphisms (SNPs), important molecular markers for genetic studies are frequent sequence variation in the plant genome. This study was performed to develop SNP markers related to gummy stem blight resistance from three watermelon lines, one susceptible and two resistant to gummy stem blight. Of them, 22 SNP primers which were sequence information on SNPs derived from comparing a resistant and susceptible line was used for high resolution melt analysis. A total of 14 candidate SNP primers were detected melt temperature difference. These SNP primers can be useful for developing disease resistance-related markers and, therefore, beneficial to watermelon breeding program.

본 연구는 주아의 적정 파종시기를 구명하고자 수행되었다. 주아를 파종할 때 파종시기에 따른 수량을 살펴본 결과 중부지역에서 추파한 경우 ‘단양마늘’의 평균 구 무게가 3.1-3.5g이었고 수확주 율은 61-71%였고 춘파의 경우 평균 구 무게가 1.8-2.8g이었고 수확주 율은 53-60%로 주아를 추파한 경우 수량이 높음을 알 수 있었고 적정 파종시기는 10월 초순이었다. 남부지역에서 ‘남도마늘’의 경우 평균 구 무게가 1.8-3.0g 이었고 수확주 율은 74-89%였고 춘파의 경우 평균 구 무게가 0.6-1.0g이었고 수확주 율은 47-56%로 주아를 추파한 경우 수량이 높음을 알 수 있었고 적정 파종시기는 9월 중하순이었다. This study was conducted to investigate the effect of planting dates using garlic bulbils for production of seed garlic. The planting dates were examined using 0.2 g bulbils of ‘Namdo’ or ‘Danyang’. For the planting dates study conducted in the middle regions, the bulbils of ‘Danyang’ planted in autumn produced bulb weight ranging from 3.1 to 3.5 g and percentage of harvest ranged from 61 to 71. The bulbils of ‘Danyang’ planted in spring produced bulb weight ranging from 1.8 to 2.8 g and percentage of harvest ranged from 53 to 60. The most desirable planting date was in the early October for the middle regions. For the planting dates study conducted in the southern regions, the bulbils of ‘Namdo’ planted in autumn produced bulb weight ranging from 1.8 to 3.0 g and percentage of harvest ranged from 74 to 89. The bulbils of ‘Danyang’ planted in spring produced bulb weight ranging from 0.6 to 1.0 g and percentage of harvest ranged from 47 to 56. The most desirable planting date was in the mid and late September for the southern regions.

본 연구는 마늘 생산비를 절감하고 마늘 주아재배의 기계화체계를 확립하기 위해서 수행되었다. 주아기계 파종시 적정 재식거리를 구명하기 위하여 재식거리를 달리하고 주아 파종시 주아파종기를 이용한 파종 및 인력파종 방법간의 비교를 수원과 남해에서 ‘단양마늘’과 ‘남도마늘’을 공시하여 실험하였다. ‘단양마늘’의 경우 재식거리는 수확주율과 통마늘 형성률에 있어서 5×3~7×3㎝로 하고, ‘남도마늘’의 경우는 7×1㎝, 7×2㎝ 및 10×1㎝ 하는 것이 적당할 것으로 생각된다. 주아기계 파종시 수확주율과 통마늘 형성률이 인력파종에 비해 감소하였으나, 생산비 절감의 측면에서 주아를 기계로 파종하는 것이 효율적일 것으로 판단된다. This study was conducted to develop an effective production of mechanization system for garlics (Allium sativum L.), in which the bulbils could be used as a seed bulb. The experiment was carried out in Suwon and Namhae. The planting distance and bulbil sowing methods were examined using 0.2 g bulbils of ‘Namdo’ or ‘Danyang’. The bulbil sowing methods were compared in their field performance using bulbil sower and conventional method. The most desirable planting distance were 5 × 3 ㎝ to 7 × 3 ㎝ in ‘Danyang’ and 7 × 1 ㎝, 7 × 2 ㎝, and 10 × 1 ㎝ in ‘Namdo’ as seed garlic for producing non cloved garlic with high survival rate. In the bulbil sowing methods, the conventional method showed higher survival rate and forming non-cloved than bulbil sower. However, in the aspect of reducing production cost in garlic, the optimum bulbil sowing was using bulbil sower.
