The study of morphological characteristics of fruits and seeds of the genus <em>Malus </em>is the key to the effective use of the apple genetic diversity in landscape-gardening, fruit growing, introductory and breeding. <strong><em>Methods</em></strong>. Morphological features of fruits and seeds of nine species and three varieties of apple (<em>M. baccata</em>, <em>M. coronaria </em>‘Red Tip’, <em>M. floribunda</em>, <em>M. fusca</em>, <em>M. halliana</em>, <em>M. niedzwetzkyana</em>, <em>M. × purpurea</em>, <em>M. × purpurea </em>‘Ola’, <em>M. × purpurea </em>‘Royalty’, <em>M. × purpurea </em>‘Selkirk’, <em>M. trilobata</em>, <em>M. tschonoskii</em>, <em>M. toringoides</em>) were studied. Generally accepted tech- niques of research was used. <strong><em>Results</em></strong>. The fruit weight of apple species and varieties varied from 0.30 g (<em>M. fusca</em>) to&nbsp;61.20 g (<em>M. coronaria </em>‘Red Tip’), the weight of 1000 seeds — from 5.00 g (<em>M. fusca</em>) to 62.77 g (<em>M. coronaria </em>‘Red Tip’). The largest number of seeds in the fruit was characteristic of <em>M. toringoides </em>(6.64), the smallest — <em>M. tschonoskii </em>(0.25); developed seeds were not detected in the fruits of <em>M. trilobata </em>for 2019–2020 years. The lowest level of variability among biometric indicators of the studied representatives of the genus <em>Malus </em>was in terms of fruit height, fruit diameter and seed height, the highest — in terms fruit weight and number of seeds in the fruit. <strong><em>Conclusions</em></strong>. Detailed characteristics of fruits and seeds of the genus <em>Malus</em>, growing in the National Dendrological Park “Sofiyivka”, were compiled as a result of research. The obtained data can be used as a supplement to the botanical characteristic, and as a comparative material for taxonomy and phylogeny.</p> ER -
