Molecular markers in the genetic diversity studies of representatives of the genus <i>Rubus</i> L. and prospects of their application in breeding

Abstract: Род Rubus L. (семейство Rosaceae Juss.), по оценкам разных систематиков, состоит из 12–16 подродов, объединяющих ~750 видов. Самые крупные по числу видов подроды – Idaeobatus (Focke) Focke, к которому относятся малины, и типовой подрод Rubus (=Eubatus Focke), включающий виды ежевик. Представители рода Rubus обладают высокой пищевой и хозяйственной ценностью, а также лекарственными свойствами. Селекционные исследования направлены на расширение генетического разнообразия и создание новых сортов малин и ежевик, у… Show more

“…Overexploitation of nature often results in habitat loss for wild resources, while habitat fragmentation leads to smaller population sizes, which will also endanger the long-term survival of R. chingii through asexual reproduction and genetic drift [ 66 ]. Therefore, it seems that poor habitat conditions, low distribution density and severe human intervention are the main reasons for the reduction in genetic diversity [ 73 ]. However, the small number of materials in some regions may not be a true reflection of the low diversity level, and further studies with larger samples are needed.…”

“…[1; 2]. Путем ДНК-маркирования проводятся выявление ценных генотипов, мониторинг генетической изменчивости исследуемого вида, его адаптации к негативным факторам среды обитания [3]. Точное определение уровня генетического разнообразия может быть востребовано для изучения и сохранения редких и исчезающих видов, в селекционных программах различного направления, в том числе для древесно-кустарниковых растений [4; 5].…”

“…The genus Rubus belongs to the subfamily Rosoideae Fokke and consists of 10 to 16 subgenera (Fokke 1910(Fokke -1911(Fokke , 1914 Huang et al 2023). Two large subgenera of raspberries (Idaeobatus (Focke) Focke) and blackberries (Rubus) establish two evolutionary lines, where isolation is con rmed by molecular genetic studies, as well as morphological features, the most important of which is the fruit structure (Alice et al 1999;Krasovskaya 2001;Kalkman 2004;Potter et al 2007; Kamnev et al 2020;Dunaeva et al 2022). Raspberries have sticky drupelets (as a result of mesocarp outgrowth) and are easily separated from the thalamus.…”
