Resistance in <em>R. americanum</em> is determined by <em>P</em> gene and in <em>R. sanguineum</em> by <em>Ce</em> gene. Both molecular markers were absent in <em>R. dikuscha</em> genome. Molecular markers related to <em>P</em> and <em>Ce</em> genes were identified in the genome of <em>R. aureum</em>. Resistance to gall mite in the field conditions in <em>R. nigrum</em> x <em>R. americanum</em>, <em>R. nigrum</em> x <em>R. aureum</em> and <em>R. nigrum</em> x <em>R. sanguineum</em> F<sub>3</sub> hybrids fitted an expected Mendelian segregation ratio of 1:1, 3:1 and 1:1, respectively. 75.0% of hybrids with a pyramidal resistance to gall mite carrying markers related to <em>Ce</em> and <em>P</em> genes were obtained in the cross combination <em>R. nigrum</em> x <em>R. aureum</em> and will be included in the future breeding programs.</p> ER -
