Abstract
Twenty-two Solanum accessions used as rootstocks were evaluated for their resistance towards the root-knot nematodes Meloidogyne javanica and M. incognita and three tobamoviruses (Tmv, ToMV and Pmmv). Five out of seven S. gilo accessions, namely Rnl 300/328, Rnl 304/337, Rnl 308/347, Rnl 297/323 and Rnl 307/346, were resistant or immune against all viruses while others within S. aethiopicum group kumba, S. linnaeanum, S. macrocarpon and S. dasyphyllum were susceptible. Furthermore, variability of plants within the same accession being either susceptible or resistant/immune to viruses was recorded in others. Both nematode species produced galls and egg masses on all tested plants.
Zusammenfassung
Zweiundzwanzig Veredelungsunterlagen der Gattung Solanum wurden hinsichtlich ihrer Resistenz gegenüber drei Tobamoviren (Tmv, ToMV and Pmmv) und den Wurzelgallenne-matoden Meloidogyne javanica und M. incognita bewertet. Die fünf (von sieben untersuchten) S.-gilo-Unterlagen Rnl 300/328, Rnl 304/337, Rnl 308/347, RNL 297/323 und RNL 307/346 erwiesen sich als resistent oder immun gegenüber allen Viren, während andere Unterlagen der Arten S. linnaeanum, S. macrocarpon, S. dasyphyllum und der S.-aethiopicum-Gruppe kumba anfällig waren. Andere Unterlagen derselben Akzession variierten darüber hinaus in ihrer Anfälligkeit oder Resistenz/Immunität gegenüber diesen Viren. Beide Nematodenarten bildeten Gallen und Eimassen an allen überprüften Pflanzen.
