| Abstract |
Southern stem rot caused by Sclerotium
rolfsii is a significant problem of Jerusalem artichoke
(Helianthus tuberosus L.) production in Thailand.
Resistant varieties are not available. The objective of
this study was to investigate genetic variability of
Jerusalem artichoke genotypes for resistance to stem
rot caused by S. rolfsii. Ninety-one Jerusalem artichoke
genotypes were evaluated under greenhouse
conditions. Traits evaluated included disease score,
lesion length, days to permanent wilting, plant height,
shoot dry weight, and root dry weight index. Number
of days from inoculation until permanent wilting was
the only trait with statistically significant differences
among genotypes. Based on this trait, genotypes were
categorized into two distinct groups: resistant and
susceptible. Genotypes that consistently expressed
relative resistance to S. rolfsii included HEL 280, HEL
278, HEL 293 and JA 98. These genotypes may be
useful to plant breeders as sources of germplasm for incorporating resistance to S. rolfsii into Jerusalem artichoke. |
