Tobacco Introduction(T.I.)의 담배 모자이크 바이러스(TMV) 저항성에 관한 연구
Studios on the Tobacco Mosaic Virus (TMV) Resistance in Tobacco Introduction ( Nicotiana tabacum L.)
초록
담배 모자이크 바이러스(TMV)抵抗性을 가진 T.L448A외 30品種을 供試하여 germplasm의 抵抗性源에 따른 特性을 調査한 結果, 무병징 Group은 국부병반Group에 比하여 長幹, 多收, 晩生種이었으며 品質과 內容成分은 낮았다. 두 group의 諸形質間 相關關係는 開花日數와 草長(r=0.8308), 品質과 還元糖(r=0.9110) 間에 正의 有意相關關係를 보였다. 국부병반 group중 T.I.1504는 TMV抵抗性品種育成에 利用이 可能할 것으로 思料된다.
Thirty-one Tobacco Introduction (Nicotiana tabacum L.) lines from Agricultural Research Service, United States Department of Agriculture, were assayed for their resistance to tobacco mosaic virus. The T.1.'s were grouped into two classes according to symptoms - symptomless and local lesion. Tobacco Introductions in the symptomless group yielded better than the local lesion group but the leaf quality was lower. The chemical composition of cured leaves was similar in both groups. Considering various agronomic characters, T.I. 1504 in the local lesion group is recommended as a new source for the breeding of TMV resistance.
