- W810852820 abstract "2001년 이후 2005년까지 북측의 씨감자 생산은 남북 협력으로 순조롭게 진행되어 일부는 이미 3급종자(G3)까지 공급되어 증식되고 있는 실정이다. 특히 씨감자 생산 체계의 상위단계인 조직 배양과 양액씨감자(G0) 생산에서는 성공적이었으며, 다음 단계인 1급(G1)<TEX>$sim$</TEX>4급종자(G4)를 어떻게 무병, 격리 조건에서 감염율을 적게 유지, 증식, 관리하느냐에 달려 있다고 해도 과언이 아닐 것이다. 벌써 상위단게 씨감자 생산의 효과가 나타나기 시작하고 있어, 특히 남북한의 지속적인 협력이 절실하다고 할 수 있다. During visiting North Korea from 2001 to 2005, I have had a few chances to observe and discuss several North Korean scientists for the seed production program and also, the occurrence of potato pests. Healthy seed production, especially in the early generations, e.g. the production of virus-free starting materials as well as in vitro pre-basic seeds (G0) by hydroponics and basic seeds under netted houses according to her new national seed potato program of Academy of Agricultural Science, Pyongyang, North Korea, has been done well so far. Some major pests occurred, however, in the early generations such as pre-basic seed (G0) in greenhouse, basic seed (G1) in screenhouse, foundation seed-I (G2) and even ware potatoes in the fields are Phytopitthora infestans, Spongospora subterrunea, Ralstonia solanacearum, Pythium spp. and some viruses such as Potato virus X, Potato virus Y, Potato leafroll virus, and also larger potato ladybeetle, greenhouse whitefly and potato tuber moth. Therefore, the success of healthy seed production in North Korea will be thoroughly depended on the pest control and the multiplication of virus-free seed stocks in the isolated areas, especially where no infected potatoes are grown." @default.
