В статье приведены результаты изучения аллельного разнообразия генов синтеза этилена Md-ACS1 и Md-ACO1 в отечественной генплазме яблони с применением ДНК-маркерного анализа. Идентифицированы аллельные комбинации данных генов у 48 сортов яблони отечественной селекции. Выявлено, что уровень распространения аллельных комбинаций, обусловливающих высокую степень лежкости плодов, в отечественной генплазме соответствует частоте их встречаемости в мировом генофонде культуры. С учетом полученных данных начата программа по созданию селекционных форм яблони, несущих сочетание аллелей Md-ACS1-2/2 + Md-ACО1-1/1, с применением ДНК-маркерного отбора для селекции сортов, обладающих наиболее высокой степенью лежкости плодов.

The allelic diversity of the Md-ACS1 and Md-ACO1 genes, involved in ethylene biosynthesis, was studied by DNA marker analysis of 48 apple varieties bred in Russia. Different allelic combinations of these genes were identified. We found that the prevalence of the allelic combinations associated with long shelf life of apple fruit in the Russian germplasm corresponded to the occurrence of these alleles in the worldwide gene pool. With regard to these data, a marker-assisted breeding program was launched to develop forms carrying the Md-ACS1-2/2 + Md-ACO1-1/1 allele combination for long fruit shelf life.
