“…The discovery of resistance genes in apricots against the plum pox virus [49] is one example within the family. Work has also been undertaken in the distantly related blackcurrant, where they found resistance genes for blackcurrant reversion virus resistance [50]. The results of our meta-analysis provide us with more focused regions of interest for a search of the candidate genes underlying RRD-resistant QTL.…”

Rose rosette disease (RRD), caused by the rose rosette emaravirus (RRV), is a major viral disease in roses (Rosa sp.) that threatens the rose industry. Recent studies have revealed quantitative trait loci (QTL) for reduced susceptibility to RRD in the linkage groups (LGs) 1, 5, 6, and 7 in tetraploid populations and the LGs 1, 3, 5, and 6 in diploid populations. In this study, we seek to better localize and understand the relationship between QTL identified in both diploid and tetraploid populations. We do so by remapping the populations found in these studies and performing a meta-analysis. This analysis reveals that the peaks and intervals for QTL using diploid and tetraploid populations co-localized on LG 1, suggesting that these are the same QTL. The same was seen on LG 3. Three meta-QTL were identified on LG 5, and two were discovered on LG 6. The meta-QTL on LG 1, MetaRRD1.1, had a confidence interval (CI) of 10.53 cM. On LG 3, MetaRRD3.1 had a CI of 5.94 cM. MetaRRD5.1 had a CI of 17.37 cM, MetaRRD5.2 had a CI of 4.33 cM, and MetaRRD5.3 had a CI of 21.95 cM. For LG 6, MetaRRD6.1 and MetaRRD6.2 had CIs of 9.81 and 8.81 cM, respectively. The analysis also led to the identification of potential disease resistance genes, with a primary interest in genes localized in meta-QTL intervals on LG 5 as this LG was found to explain the greatest proportion of phenotypic variance for RRD resistance. The results from this study may be used in the design of more robust marker-based selection tools to track and use a given QTL in a plant breeding context.

Since controlling currant gall mite (Cecidophyopsis ribis Westw.) is a challenging and ineffective task, developing genetic resistance to the pest is one of the main priorities in breeding programs for Ribes nigrum both in Russia and abroad. The task was assigned at the FSBSO “Federal Horticultural Center for Breeding, Agrotechnology and Nursery” to combine efficiently the positive economic and biological traits of previously developed varieties with resistance to phytophagous pests in hybrid progeny. The study evaluates the genetic collection and hybrid material of black currant for resistance to currant gall mite, as well as identifies the most promising parent pairs for mite-resistant progeny. The research objects included 107 varieties of various genetic origins, 30 of which were of foreign breeding. An assessment of the genetic collection carried out for ten years (since 2012) during the seasons of mass manifestation of the currant gall mite and reversion, is presented. Approximately 1,200 seedlings, planted in 2017, were studied. The methodologies for studying fruit, berry, and nut crops were used to assess the degree of incidence of the currant gall mite. The statistical processing of experimental results was performed using the Microsoft Excel program. As a result, the genetic sources and donors of resistance to the currant gall mite were identified (Barmaley, Dar Smolyaninovoi, Kipiana, Svityazyanka, Chernooka, Wonderful Moment, Ben Hope, Big Ben, etc.). The promising combinations of crosses were identified based on the yield of seedlings resistant to Cecidophyopsis ribis: Ben Hope×Kipiana, Ben Hope×Dar Smolyaninovoi, Kipiana×Dar Smolyaninovoi, Barmalei×Dar Smolyaninovoi, Ben Tirran×Kipiana, 9-28-1/02×Bryansk Agate, Dar Smolyaninovoi×33-27-1, 33-27-1×Kipiana. In the progeny of these parental forms, the selected forms were identified (3-63-01, 3-63-02, 9-197-3, 3-16-1, 7-28-01, 8-123-1), which combine resistance to the currant gall mite with large fruits and tolerance to fungal diseases.
