Evaluation of Two Field Inoculation Methods for Testing Resistance to Bacterial Fruit Blotch in Watermelon Fruit
Bacterial fruit blotch (BFB) caused by Acidovoraxcitrulli is a major seed-borne disease that affects watermelon (Citrullus lanatus) seedling and fruit production around the world (5,9). A. citrulli can infect all growth stages of the watermelon plant: seeds, seedlings, foliage, flowers, and fruit(5). The scant research on fruit resistance in favor of foliar resistance has three […]

Pathotypes and Races of Pseudoperonospora cubensis – Different Concepts of Virulence Differentiation
Host-parasite interactions between Cucurbitaceae and P. cubensis exhibit significant variation. This contribution reviews the current state of knowledge regarding characterization of P. cubensis virulence variation on the level of pathotypes (variation in host genera and species host-range) and races (variation in intraspecific level). However, our knowledge of the interactions between P. cubensis isolates and the […]
Cucurbit Powdery Mildew Population Virulence Variation – a Complex View from a Global Perspective
Cucurbit powdery mildew (CPM) is mainly caused by two obligate ectoparasites, Golovinomyces orontii s.l. (Go) and Podosphaera xanthii (Px), that are highly variable in virulence. Various independent systems of CPM race determination and denomination have been used in recent decades. We recently developed new tools to enhance research of CPM virulence variation. Diversity models were […]
