The spotted wing drosophila(Drosophila suzukii)is one of the serious fruit pest that has a wide range of fruit crops like blueberries, cherries and grapes. It came up the larvae cause dagmage by feeding on the pulp inside fruits and berries and spotted wing drosophila also has a adversely affect export to Austrailia and New zealand as a quarantine pest. This study conduct to survey occurrence of drosophila spp. from 2016 to 2018 on harvest period of grapevine in vinyard of Okcheon ,Yeongdong and fruit packing place for export to New zealand and USA. Vinegar and wine mixture was used to attract fruits flies. We also investigated to what color is the best stimulus to catch a vinegar flies. Our result shows that significant differences were observed in total flies trapped in red and black colors. This study will contribute to future research for monitoring and control drosophilid flies.

A new sesame variety “Jinki” was developed from Yeongnam Agricultural Research Institute in 2005. The cross was made by high quality and yielding “Jinbaek” to the F1 hybrid of “Suwon 129” with high yield capacity and “ALM3” with disease resistance, follow

A new sesame variety “Kopoom” was developed from Yeongnam Agricultural Research Institute in 2005. The cross was made by shattering resistance F1 hybrid of Dongro x SC645 to the high yielding capacity F1 hybrid of Yoosung x Mokpo 9, followed by pedigree s

“Saebora” is a new leaf vegetable perilla (Perilla frutescens (L.) Britton) variety developed from a cross between “Ipdeulkkae1” and YCPL199 at the Yeongnam Agricultural Research Institute, NICS, RDA, in 2004. Purple backside leaf color is a very importan

“Sangbeak” (Perilla frutescens (L.) Britton), is a cultivar for leaf vegetable, from a cross between YPL5 (Ipdeulkkae1/ YCPL187) and “Namcheon” at the National Yeongnam Agricultural Experiment Station (NYAES), RDA, in 2003. The size of fully grown leaf is a important trait in delayed harvesting. The maximum leaf size of “Sangbeak” is 18.5cm, smaller than 21.4cm of a check cultivar, “Ipdeulkkae”1, leading to the constant leaf quality in delayed harvest. The fresh leaf yield of “Sangbeak” is 6% higher than that of “Ipdeulkkae 1” (5029 vs. 4742 kg/10a). For the leaf production, “Sangbeak” could be grown in whole area of South Korea. However, because of its late maturity, seed production culture is available in South Gyeongsang and South Jeolla provinces.

New balloon flower (Platycodon grandiflorum) variety, ‘Jangbaek’, had been developed by pureline selection from some native cultivars collected in Milyang by the medicinal crops research team of the National Yeongnam Agricultural Experiment Station at 200

개간지에서 대두를 재배함에 있어서 시비의 효과를 구명하기 위하여 개간지에는 10a당 N.P.K:4.10.8 kg의 시용구를 비롯하여 무비구를 포함한 6개 처리구를 설치하고 효과를 비교하고저 따로 숙전에다 N.P.K:4.10.8 kg의 시비구를 설치하여 수량과 성분함량을 조사한 결과를 요약하면 다음과 같다. 1. 개간지는 같은 수준의 시비에서도 숙전보다 청예수량이나 자실수량이 극히 적었고 자실의 단백질함량도 적었다. 2. 같은 개간지내에 있어서는 질소의 시용량이 많을수록 자실수량이 많았다. 3. 자실성분에 있어서 숙전은 단백질과 지방함량이 개간지보다 많았고 탄수화물은 개간지가 숙전보다 많은 경향이었다. 4. 개간지에 있어서 자실성분함량은 처리간에 유의성이 인정되지 않았다. 5. 수량과 밀접한 관계가 있는 100입중, 1주협수 간장 간중등은 자실수량과 정의 상관을 나타냈으며 1%수준의 유의성이 인정되었다.
