В результате молекулярно-генетического исследования селекционной коллекции отобрали 5 линий, которые прошли испытание в системе полного диаллельного скрещивания. Гибриды F1 в большинстве комбинаций достоверно превосходили родителей по основным хозяйственно ценным признакам. Анализ сопряженности дивергенции родительских форм с компонентами урожая F1 показал, что существуют достоверные корреляции (r &gt; 0,5) между уровнем GD и основными компонентами продуктивности. При этом продуктивный потенциал прямых гибридов F1 на 67,2 % (R = r2) предопределен общей GD родительских форм, тогда как для реципрокных F1 статистически значимых связей не обнаружено. Вероятно, формирование высокопродуктивного гетерозисного генотипа не настолько связано с общей гетерогенностью гибридного генома, как с полиморфизмом в отдельных специфических локусах, которые обусловливают высокую экспрессию признаков в F1.</p></abstract><trans-abstract xml:lang="en"><p>The prediction efficiency of white cabbage F1 hybrid performance based on ISSR and RAPD markers was carried out. In result molecular-genetics evaluation of white cabbage collection, five divergent lines were selected and tested by full diallel (5×5) mating design. Through analysis relationship genetic divergence of parental lines and F1 hybrid performance the significant correlations (r &gt; 0.5) were found for the main yield components. Yield potential of half-diallel F1 hybrids was predetermined total GD by 67.2 % (R = r2), whereas no significant associations were found for reciprocal F1. Consequently, heterotic response does not simply result from the overall genetic diversity within a hybrid, but is likely only diversity at some specific loci causing the formation of superior F1 genotype with high expression of the traits.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Snowdon R.
