Prunus domestica 'Krymsk 1' is a popular semi-dwarf rootstock suitable for a wide range of stone fruits, including Japanese and European plums, peaches, apricots, mirabelles and damsons. Developed by the Krymsk Experimental Plant Breeding Station in Russia, this rootstock offers an excellent choice for growers looking for a versatile, precise and healthy rootstock for their fruit trees.<\/p>\n
Key features:
\nVigour: 'Krymsk 1' is semi-dwarf, with vigour ranging from 50% to 60% of standard varieties such as Nemaguard or Lovell in peaches and apricots, and 0 to 70% in plums. This makes the rootstock ideal for crops where control of tree growth is desired, without loss of fruit production.
\nSoil type adaptation: This rootstock performs well on a variety of soil types and even copes well with heavier soils. It has moderate tolerance to calcareous soils and is resistant to waterlogging.
\nClimate adaptation: The 'Krymsk 1' resists both cold and heat well, with excellent cold resistance suitable for USDA Zone 4A and strong heat resistance.
\nResistance and diseases:
\nDiseases: Although 'Krymsk 1' shows some susceptibility to root-knot nematode, ring nematode, crown nodule and bacterial canker, it also offers good resistance to root-ellezion nematodes and reasonable tolerance to other common diseases.
\nAnchoring and root storage: The rootstock has good anchoring and shows little root storage, which contributes to tree stability.
\nGraft compatibility:
\nGraft compatibility: 'Krymsk 1' offers excellent compatibility with European and Japanese plums, and with apricots such as Apache, Robada and Orangered. However, compatibility with peaches and nectarines is not as good.
\nPropagation and propagation:
\nPropagation: 'Krymsk 1' can be propagated well via hardwood and softwood cuttings, as well as meristem cuttings in vitro.
\nConclusion:
\nThe 'Krymsk 1' rootstock offers growers an ideal choice for a wide range of stone fruits, with an excellent balance between growth regulation, fruit production and disease resistance. Thanks to its versatility in soil and climate adaptation, as well as good graft compatibility with various fruit varieties, 'Krymsk 1' is a reliable choice for both commercial and hobby growers.<\/p>","protected":false},"excerpt":{"rendered":"
