PROSPECTS OF USING DNA-MARKERS IN GRAPEVINE BREEDING [PDF]

Russian Vine, 2021
DNA-markers are actively used for the fin-gerprinting of genotypes, identification of va-rieties, in phylogenetic studies, for assessing genetic diversity, for mapping genes, etc. The article presents an analytical review of the achievements in the use of molecular markers in grape genetics as a basis for breeding works.

Phased grapevine genome sequence of an Rpv12 carrier for biotechnological exploration of resistance to Plasmopara viticola

Frontiers in Plant Science, 2023
The downy mildew disease caused by the oomycete Plasmopara viticola is a serious threat for grapevine and can cause enormous yield losses in viticulture. The quantitative trait locus Rpv12, mediating resistance against P.

Extent of wild–to–crop interspecific introgression in grapevine (Vitis vinifera) as a consequence of resistance breeding and implications for the crop species definition

Horticulture Research, 2022
Over the past two centuries, introgression through repeated backcrossing has introduced disease resistance from wild grape species into the domesticated lineage Vitis vinifera subsp. sativa.

Dissecting foliar physiology and chemical properties with integrated highthroughput phenotyping and molecular markers in grape improvement

, 2023
An advanced phenotyping protocol using a hyperspectral spectrometer to better understand foliar chemical composition and physiological processes in relation to grapevine yield, quality, biotic and abiotic resistance was initiated with in-house and public

High-Precision Phenotyping of Grape Bunch Architecture Using Fast 3D Sensor and Automation

Sensors, 2018
Wine growers prefer cultivars with looser bunch architecture because of the decreased risk for bunch rot. As a consequence, grapevine breeders have to select seedlings and new cultivars with regard to appropriate bunch traits.

Across-population genomic prediction in grapevine opens up promising prospects for breeding

bioRxiv, 2021
Crop breeding involves two selection steps: choosing progenitors and selecting offspring within progenies. Genomic prediction, based on genome-wide marker estimation of genetic values, could facilitate these steps.

Grapevine genetic resources of Armenia: molecular fingerprinting and phylogenetic relationship among wild and cultivated grapevine

, 2023
Armenia is characterized by a high diversity of cultivated (Vitis vinifera L. subsp. Vinifera) and wild (Vitis vinifera L. subsp. sylvestris) grapes. The country has played a leading role in the centuries-lasting history of grapevine cultivation in the ...

Identification of sex determination locus and development of marker combination in Vitis based on genotyping by target sequencing

Fruit Research, 2023
The grapevine is an important and economically valuable fruit crop, with flower sex being a key genetic trait that directly affects grapevine yield and quality. Despite its significance, there is a lack of studies on sex-linked molecular markers that can
