Abstract: Six novel peach genotypes, designated BN-1, BN-3, BN-4, BN-7, BN-8 and BN-45, were assessed for usefulness as sources of seeds for production of generative rootstocks for peach cultivars. The genotypes BN-8 and BN-1 were the most intensely flowering, while the most abundantly and regularly fruiting genotype was BN-8, which also produced the smallest stones. The smallest fruits and the highest seed yields were produced by the genotypes BN-8 and BN-7. All of the genotypes under assessment produced seeds with higher germination capacities compared with the two control cultivars, Mandżurska and Siberian C, with the seeds of the genotypes BN-8, BN-4 and BN-3 exhibiting the most significantly elevated germination capacities. The most stones with two seeds were produced by the genotypes BN-45 and BN-3; however, produced a smaller fruit crop than did BN-8. Considering the characteristics assessed, the best as a seed source trees was genotype BN-8.
