Among the mold diseases of black currant the most dangerous is puccinia ribesiicaricis, which in period of sufficient conditions lowers yield and quality of berries of black currant in 3–4 times. The results of our researches certify that the growth of our researches certify that the growth of resistant plants (Iubileina Kopania, Kozatska, Chereshneva) against puccinia ribesiicaricis ensures the increase of yield up to 1,2 t/ha, the net income herewith increases from 40717 to 52973 UAH/ha, and coefficient of energetic efficiency totals 1,79 units.
