Abstract:
Seedlings out of 11 autochthonous plum genotypes and 4 myrobalan genotypes served as the starting point for the selection of vegetative plum rootstocks. Out of the evaluated autochthonous genotypes, 4 selections belonging to Prunus domestica L. and 1 selection belonging to Prunus cerasifera Ehrh. were singled out. Selections belonging to Prunus domestica L. namely, 5/7; 3/3; and 4/2 are moderately vigourous, while, 2/53 is of low vigour. All the selections form numerous roots, 10 cm in average long. Rooting zone is large, while, rooting index ranges from 4.19 up to 10.29. One selection was obtained from Prunus cerasifera Ehrh. (6/209). It is moderately vigourous. It forms numerous roots (11), 18.45 cm in average long. Rooting index amounts to 4.64, whereas, rooting zone is large. Selections, which were singled out, have successfully been propagated by in vitro culture, and according to the observed parameters of rooting, 6/209 selection showed the best results, followed by 2/53 and 5/7.
