  • Report on pierce disease grape research

    As previously reported we are researching/breeding grape varieties suitable for SE USA thatresist pierce disease that prevents successful bunch grape culture in many areas and states.
    Th9s year no disease noted on the mother vines and fruit report below:

    Stover(once sold by nurseries for homeowners) goodcrop green juicy seeded grapes about size of a concord flesh is medium soft skin not tart and is edile seeds small we swallow them. would be good juice/jam but low acid for wine but fine for juice.Is one of the pollensources for our breeding experiments
    CARIBE: queen of the varieties. never offered by a nursery vigorous vines, heavy fruiting grapes size of a red globe seeded,thin green skin..low acid but sweet.zero wild grape flavor rather like vinifera taste.main breeding parent for us here but have others not yet fruiting to evaluate. I may later offer pure CARIBE vines for sale.why never offered by a nursery is a mystery but they generally only sell varietiesof anything'average homeowners" ever heard of.Caribe is superb table grape and juice, low acid for wine I suspect but fine for processing, skins thin and edible

    commercially available bunch grapes do lousy here even"PD"resistant ones like coquistador.

    we are currently testing EVEREST a nursery available one reportedly like a giant seedless concord.unsure its PD resistance however

    So the research is targeted at PD resistant American hybrid table grapes varieties? Have you looked at Victoria Red?

      ,Naturaly,have 4mature vines.do notlike soil/climate here. may consider using as a breeding pollen source.Light cropshere tosay theleast.also most dark skin ones from TX with resistance have rather unpalatablle small fruit here except a few and all a bIt acid.the whites do include palatabe table grapes ,LIKE WETUMPKA ,WAPAKUKA etc. could not get ELLEN SCOTT to test

    What root stock are you using? I’m using 1103P and a friend in Victoria is using 1103P/Salt Creek due to varying soil conditions. VR can have an issue with Downy Mildew.

      Yatama, Caribe sounds like a winner! Would like to try that one. Also had been thinking of giving Everest a trial. Keep us posted if you decide to release Caribe plants or cuttings. Thnx for the update and good luck with your P.D. research. Randy/GA

        well guys eventually do plan to release CARIBE after bit more experience and so am planning producing more vines of it so as to have volume to send out to fellow enthusiasts.Here one of besttable grapes I have among maybe 20 testing.But my growing conditions rather unlike most other areas of USA.Looks like Caribe can take fairly soggy soils but also my sandy areas long as get some irrigation. not sure how would take X colder than Z7 as has tropical genes as well as vinifera ones ,When I get material for others will announce here.
