For the effective development of modern industrial gardening, it is necessary to maximize the use of the biological potential of cultivated varieties of fruit crops. In order to identify the most valuable for use in breeding and production of varieties and elite forms of apple regional and foreign selection studied the features of growth and fruiting of apple genotypes. The objects of study are 14 varieties and 2 elite forms of apple. In the work, programs and methods of selection and sorting studies that are generally accepted and developed with the participation of employees of the FSBSI NCFSCHVW were used. According to the results of many years of research, low-growing apple varieties that are promising for breeding and production have been identified: the Golden Crown, Carmen, Favorite Dutovoy, Red Chif, Sunrise, Novella, Talisman, and the elite form 12/2-20-35. Low-growing varieties with a convenient vertical crown are distinguished: Carmen, Favorite Dutovoy, Red Chief. Selected varieties of regional breeding: immune to scab Carmen and highly resistant to scab Favorite Dutovoy, possessing a complex of significant features: fruitful, low growth, with a vertical form of crown as the most valuable for use in breeding and production
Industrial horticulture assumes the most effective use of
the potential of varieties. One of the key factors
determining the yield of garden plantings is the
effectiveness of pollination. To obtain the maximum
yield, it is necessary to ensure maximum pollination
during the flowering period. For this reason, much
attention has been paid to the selection of pollinators.
Crab-apple forms are promising for use as pollinators, so
this work was aimed at identifying the most common
alleles of the self-incompatibility gene in the crab-forms
using the molecular genetic method of analysis. The
object of the study was 29 apple-tree creams and 3 elite
selection forms. They carried out the molecular genetic
identification of alleles S2 and S10, which are among
the most common apple trees in the world gene pool.
Allele S2 was identified in 16 samples (14 forms and 2
elite selection forms), while S10 allele in one
sample (elite form 12/2-20 (24-28)). Data on the allelic
composition of the S gene in the samples studied are of
value for the formation of a genetic passport on the
compatibility of the studied samples of apple with
modern industrial varieties
