: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 생산비를 절감하고 마늘재배의 기계화체계를 확립하기 위해서 수행되었다. 기계파종을 전제로 하여 주아로부터 유래한 통마늘의 종구 이용성을 검토하기 위해 파종 깊이와 파종각도를 달리하여 수원과 남해에서 ‘단양’과 ‘남도’를 공시하여 실험하였다. 통마늘의 파종깊이는 8㎝ 정도로 하는 것이 적당할 것으로 생각되며, 통마늘은 파종각도가 클수록 수량과 수확주율이 감소되니 인편마늘에 비해서 그 감소율이 적었으므로 파종각도가 다소 크더라도 수량의 감소가 적어서 통마늘로 기계 파종하는 것은 인편을 이용하는 것보다 효율성이 높은 것으로 판단된다. This study was conducted to develop an effective production of mechanization system for garlics, in which the non-cloved bulbs could be used as a seed bulb. Non-cloved and cloved bulbs produced from the bulbils were compared in their field performance according to planting methods with those cloves produced conventionally. The most desirable planting depth was 8㎝ using 3.5g ‘Namdo’ or 4.5g ‘Danyang’ of non-cloved as seed garlic for producing high quality garlic. In the planting angle methods, non-cloved garlic showed much yield and higher survival late than cloves. The survival late of seed garlics in the field was decreased as the planting angle increased.

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.
