Abstract
In cornelian cherry, the macroscopic evidence /distorded and mosaic patterned basal leaves, missing opposite leaves in lower part of shoots, shortened and thickened shoots, leaf changed in size and thickness/, the microscopic evidence /stomatal and pollen size, chromosome number, pollen germination, stainability and appearance of aborted pollen/ confirm development of colchiploids.
In most cases we found diploid-tetraploid or aneuploid cytochimeras, however, one clone with tetraploid features was identified.
At acute and chronic radiation of strawberries we found LD50 at dose 30 kR for rooted plants and 20 kR in vitro explants.
Two plants nearly coresponding to some important breeding aims were selected.
By plums, apricots, redcurrants and goosberries treating with mutagens we obtained mutants with less-vigorous growth habit and ones with changed fruit quality and yield characters.
