Selected pathogens of fomos were identified as Rhoma exigua var. exigua Various methods of infecting tubers have been tested for the development of a laboratory method for assessing the selection of potato material to fomos. Selected methods in which the degree of defeat of tubers differs to a small extent, which allows to attribute the evaluated material to one group of stability. In order to develop a field method for assessing the stability of the potato breeding material to fome rot, planting the potatoes was carried out on an artificial infectious background, created in various ways. The largest number of affected daughter tubers was noted in the variant with insertion into the wells of infected grain using cut tubers.  The laboratory assessment of the stability of the 51st sample of potato obtained from the Institute of Potato Studies of the National Academy of Sciences (IC) and the Ukrainian Institute of Plant Varieties Examination was carried out. Relative resistance to the disease was noted varieties of Bernin, Madison, Myroslava, Solita. Product Description popup.authors Андрійчук Тетяна Олександрівна popup.nrat_date 2020-04-02 Close
