Erwinia carotovora subsp. carotovora에 의한 비트 세균성 무름병
박덕환,원선영,황수경,원선영,임춘근 한국식물병리학회 1998 Plant Pathology Journal Vol.14 No.5
Bacterial soft rot caused damage to beets massively grown in Pyungchang, Kangwon province, Korea. The affected roots and stems became cream colored and slimy, and turned black, causing the plants to become wilt and die. The casual organism isolated from the infected plants was identified as Erinia carotovora subsp. carotovora based on physiological and biochemical characteristic, and the results of the Biolog program (Biolog Inc., U.S.A.). E. carotovora subsp. carotovora is the first discribed bacterium which causes bacterial soft rot on beet in Korea.
Improvement of Resistance to Late Blight in Hybrid Tomato
박덕환,Yan Zhang,김병섭 한국원예학회 2014 Horticulture, Environment, and Biotechnology Vol.55 No.2
Late blight is one of the major diseases in tomato cultivated both in the greenhouse and the field. In thiswork, we determined the resistance levels of all progeny lines (F1 to F3) and a new variety (NV) F1 to the late blightdisease fungus to evaluate these hybrid lines as potential sources of resistance. The experiments were carried out ingreenhouse conditions in a completely randomized block design with three replications. Fifteen out of 204 F2 plantsof cross A (AV107-4 × L3708) and 13 out of 203 F2 plants of cross B (Campari × 917 × L3708) were found to beresistant to late blight in combined data from greenhouse trials. In addition, 5 resistant F3 lines derived from each ofthe two crosses A and B were selected for further investigation. By screening the NV F1 hybrids obtained by pollinationof the F3 lines by 3 male-sterile cultivars (Wonung-1, 2, and 3), two stable resistant hybrids, Wonung-2 × A120 andWonung-3 × B23, were finally produced. An examination of the qualitative characters in the NV F1 hybrids indicatedimproved fruit weight and quality. Taken together, our screening results indicate that both of these hybrids are goodsources of resistance and have high-value horticultural characters, which can be used for tomato breeding programs.
