  20–22 and 5–7 years of kind collection of 100 cultivars studied phenology and fl oral morphological basis of characteristics in 1994–1998 and 2009–2011. The varieties were collected 3–5 trees in the gene garden, all were on C. 359 myrobalan seedling. Detecting differences between the test cultivars are suitable for stamps, and also show that relatively short-term observations are useful for describing the comparison, to distinguish varieties. The taxonomic ordination of cultivars and groups of fruits suitable to distinguish colors shown that the fl owering and ripening time, the nature of the reproductive organs and even Sharka-rate sensitivity is associated with those groups. Differences between the age of trees mainly sexual organs and fertility were shown. Affecting rate of climatic effects was not as large as the first line of erratic rainfall, air temperature spikes or possible values would be expected. The results of the breed, a gene bank of perception, in particular, the localization of hybrids, clone-type variants are useful in the analysis. Among other things – this is due to late-maturing, relatively well-stored temporarily, and not-blue plums, Sharka-infected tolerant or resistant varieties selection (cf. SURÁNYI 2013a-c) and will be disseminate in Hungary.
