Downy mildew (Plasmopara viticola) and anthracnose (Sphaceloma ampelinum) are two major diseases that severely affect most grapevine (Vitis vinifera) cultivars grown commercially in Thailand. Progress of conventional breeding programs of grapevine for improved resistance to these diseases can be speeded up by selection of molecular markers associated(More)
Anthracnose of grapevine, caused by the fungus Sphaceloma ampelinum de Bary, the anamorph stage of Elsinoe ampelina, is one of the major diseases of grapevine (Vitis vinifera L.) in the tropics. Ten grapevine cultivars/lines and 24 F1 hybrids were evaluated for resistance to anthracnose in the laboratory, using an excised leaf technique with two anthracnose(More)
In vitro mutagenesis of Dendrobium 'Earsakul' was carried out by incubating the protocorm-like bodies in 0-5 mM sodium azide for 1 h. Twenty-eight putative mutants were evaluated for genetic variability compared to untreated control plants using inter-simple sequence repeat (ISSR) analysis. Polymorphic fragments were produced by 9 of 12 ISSR primers. A(More)
