A study of pollen grains of Iris hybrida hort. plants was conducted in the Forest-Steppe growth conditions of Ukraine. Pollen fertility and viability of 8 varieties were analyzed. Indices of fertility varied from 91,1 (Tashkent) to 98,7 % (River Hawk). The best artificial growth medium for pollen germination was established to be 10—15 % sucrose solution with 2,5 % agar. In a 10 % sucrose solution the viability of male gametes varied from 59,1 (River Hawk) to 84,7 % (Latin Rock), in a 15 % solution — from 42,0 (Before The Storm) to 90,0 % (Latin Rock).
