Wild pear (Pyrus commu nis var. piraster (L.) Ehrh.) is widely used as a generative rootstock for pear grafting. Seeds for the production of this rootstock should be taken from the registered mother plants. The a im of this research was to select mother plants in wild pear population from three localities (Banja Luka, Manjača and Potkoza rje). Fruit bearing regularity of selected trees was observed from 2012 2016, and the number of seeds per fruit was analysed in 2013, 2015 and 2016. Seed germinab i lity and vitality analysis was carried out on 14 selected tress ( genotypes )). Seed germinabili ty was tested according to the ISTA guideline . Seed vitality was determined by the tetrazolium test ( Accessions from Banja Luka locality expressed the hig h est fruit production . The hig h est number of seed s was determined in the genotypes marked as No. 6 and No. 21 amounting to 7.53 and 7.21 seeds, respectively. Seeds of the tested wild pears have show n good vitality. The hig h est seed vitality and germination of 92% was obtained from the accession No. 20. On the basis of the results, accessions marked w ith numbers: ‘6’, ‘8’, 20 ‘, ’25’, ’31’ and ’32’ can be used as mother plants for pear rootstock production.
