| Abstract:
The Far East Experiment Station (FEES) of the N. I. Vavilov All-Russian Institute of Plant Industry (VIR) is close to N. I. Vavilov’s east Asian genetic center of origin of cultivated plants. This location provides access to a wide genetic diversity of fruit and berry plants and their wild relatives in the Far East of Russia. One of the objectives of the Institute is to study the diversity of local wild species. Ribes L. plants have been intensively investigated at FEES for more than 50 years. Besides estimating wild diversity, scientists are selecting the most valuable plant material as advanced breeding selections. Fifteen wild Ribes species are native to the Russian Far East territories. Extensive explorations of wild Ribes have identified the locations of the widest genetic diversity for in situ conservation sites. FEES maintains an ex situ field genebank with accessions which are adapted to the local climate. The development of interspecific crosses is the best way to produce cultivars adapted for the broad needs of the Russian Far East. The following Ribes species are recommended as sources for cold hardiness: R. dikuscha Fisch., R. pauciflorum Turcz., R. fontaneum Boczkarn., R. procumbens Pall., R. manschuricum (Maxim.) Kom., R. pallidiflorum Pojark., R. palczewskii (Jancz.) Pojark; for white pine blister rust and leaf spot resistance, R. dikuscha, R. pauciflorum, R. procumbens, R. fontaneum; for reversion resistance, R. dikuscha, R. procumbens; for Septoria leaf spot resistance, R. pauciflorum; for blackcurrant gall mite resistance, R. pauciflorum, R. procumbens; for self-fertility, R. dikuscha; for multi-flower strigs, R. fontaneum, R. manschuricum, R. pallidiflorum; for multiple strigs, R. dikuscha, R. pauciflorum; for large fruit size, R. dikuscha, R. pauciflorum, R. procumbens, R. manschuricum. Wide interspecific crosses of the above species will produce cultivars suited to all Russian climatic zones, including those from the south of Primorye to the Magadan region and north Chukot. | |
