Exserohilum turcicum causes northern corn leaf blight (NCLB), an important disease occurring in maize producing areas throughout the world. Currently, the development of cultivars resistant to E. turcicum seems to be the most efficient method to control NCLB damage. Marker-assisted selection (MAS) enables breeders to improve selection efficiency. The(More)
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(More)
Stem rot caused by Sclerotium rolfsii is an important problem of Jerusalem artichoke, and breeding of Jerusalem artichoke for resistance to stem rot requires effective screening methods. The objective of this study was to compare methods for inoculating Jerusalem artichoke with S. rolfsii under field conditions. A 4 × 2 × 3 factorial in a randomized(More)
Stem rot caused by Sclerotium rolfsii is a major problem in Jerusalem artichoke production. Breeding of Jerusalem artichoke for stem rot resistance is a promising method for disease control, and identification of sources of resistance is necessary to initiate Jerusalem artichoke breeding programs. The objective of this study was to characterize the(More)
