Opracowano test laboratoryjny umożliwiający określenie odporności grochu (Pisum sativum L.) na porażenie przez grzyby z rodzaju Fusarium. Test ten polega na obserwacji kiełkowania nasion grochu w obecności płynnego inokulum otrzymanego z wybranych szczepów grzyba. Opracowana metoda może być przydatna do selekcjonowania materiału hodowlanego lub do oceny stopnia odporności odmian grochu na fuzariozę.
In the years 2003-2004 the resistance of 40 cultivars potato cultivated under different conditions to late blight, black leg and soft rot was compared. The experiment was performed on 7-week old plants cultivated in the field or from pathogen-free in vitro cultures. The deteched leaves, stem sections and tuber slices were artificially inoculated under laboratory conditions. A significance of differences in sporulation density of Ph. infestans and bacteria Erwinia was observed between groups of potato cultivars. A higher susceptibility of plant tissues and tubers was observed in the material obtained from the field. A significantly lower susceptibility to those pathogens was noted in late potato cultivars and early and mid-early genotypes proved their higher susceptibility.
