This article describes the peculiarities of morphological and anatomical structure of generative organs of intergeneric hybrids Cydonia x Malus. Distant hybrids differ in the number of flowers in an inflorescence: 1-4, but solitary flowers predominate in 5065% of paternal triploids. Solitary flowers predominate in 97-99% of maternal triploids and tetraploids and 1-3% of them have inflorescences with 2 flowers. Solitary flowers predominate in 75% of diploids and 25% have inflorescences with 2 flowers. It has been established a directly proportional correlation between the polyploidy level and the size of the pollen grain. Tetraploid plants are distinguished by higher pollen viability (56-67%) as compared with other hybrids, the viability of the pollen of which reaches 10%. The similarities and differences of characters in the structure of the pericarp of hybrids Cydonia x Malus are highlighted. The studied hybrids differ qualitatively (in the uneven thickening of the cell walls of epidermal cells, in the location and density of sclereids in the subzones of the mesocarp, in the shape of the exocarp and endocarp) and quantitatively, in the size of cells from the zones and subzones of the pericarp.
