In this research, we investigate the genetic polymorphism of raspberry varieties and a promising hybrid bred at Federal Horticultural Center for Breeding, Agrotechnology, Nursery. The research objects were following varieties: Penguin, Skromnitsa, Arisha, Komsomolskaya Pravda, Ivan Kupala, Salut, Lavina, Yubileynaya Kulikova, No. 10-165-11. To differentiate studied genotypes by degree similarity, an SSR marker analysis was performed using 15 loci: RhM011, RiM019, RhM003, RiG001, Rubus123a,...

Genetic stability of plants under in vitro cultivation plays a crucial role selecting elite genotypes and obtaining certified planting material the corresponding variety. Previously, assessment plant genetic involved mainly phenotypic biochemical methods, which have their advantages disadvantages. However, recently, molecular flow cytometric methods been actively developed. Therefore, comprehensive methodology for assessing should be This study aims to assess Vityaz Alpha varieties garden...

Viral damage produces a significant detrimental effect on raspberry plantations. Raspberry bushy dwarf virus ( RBDV ) appears particularly harmful, capable to significantly reduce yields. The high prevalence of is due its ability be transmitted by pollen and the absence visible symptoms plants during first stages infection. Breeding -resistant varieties can caused Therefore, search for genetic markers resistance considered relevant. At present, Bu gene identified with dominant mode inheritance...

The development of stone fruit varieties that meet modern production requirements is a labor-intensive process involving low yields progeny obtained through controlled intraspecific and interspecific hybridization, which can take up to 25 years. non-viability hybrid seeds caused by the abortion embryo does not have time complete its morphophysiological endosperm in hybrids. It possible preserve hybrids having unique combination traits removing embryos derived from intergeneric crossing are...

Common plum ( Pr unu s domes t ica L. ) is one of the fruit crops that are particularly difficult to study genetically. Unlike most other species genus , it a hexaploid (2n=48) originating from complex interspecific hybridization, and question its origin yet be conclusively resolved. Presently, several studies available examine phylogeny systematics in general specifically speciation with use molecular genetics methods. Although SSR marker method widely adopted practice studying important...

The article presents the results of DNA testing for 21 raspberry cultivars using ISSR-PCR method to study genetic polymorphism and identify genotypes potentially resistant bushy dwarfvirus (RBDV). It was revealed that promising hybrids everbearing (Rubus idaeus L.), including 9-155-1, 11-165-10 9-163-1, exhibited significant relations with RBDV-resistant cultivars. Hybrids 9-163-1 11-165-10, both having hybrid 13-118-1 as one parent forms, were grouped cultivar ‘Poklon Kazakovu’. These forms...

Abstract Due to the lack of effective means specific prevention rubella in pond fish (CRF), it is obvious that early diagnosis one most important and ways combat this disease. This theoretical study devoted development an express method for rapid detection antibodies pathogens (Aeromonas punctata, Pseudomonas, Rabdovirus cyprini). To date, CRC (Rabdovirus cyprini) determined by results clinical picture, taking into account anatomical data, epizootological indicators virological research...

A Branch of modern biotechnology for creating unique relevant genotypes is bioengineering that harnesses a spectrum plant genome modification technologies. The study aimed to analyse the current state art in fruit and berry crops more significant (vs. premium pure breeding varieties) deviations norm traits properties biotic abiotic resistance, productivity, quality, etc. First horticultural crop transformation studies at developing protocols based on selectable enzyme marker genes...
