Variability for resistance to Fusarium solani culture filtrate and fusaric acid among somaclones in pea

Pea somaclones of cultivars Adept, Komet and Bohatýr were obtained after selection in vitro with Fusarium solani filtrate and fusaric acid (FA). R2 regenerants were analyzed by RAPD and IRAP markers. Some markers were useful for clear discrimination between selected and non-selected variants of all studied cultivars.Flow cytometry analysis proved the same genome size of selected and non-selected pea lines. Therefore in vitro selection by pathogen derived agents could be the efficient method for obtaining pea somaclones with incrreased resistance to F. solani.
