Apple Rootstock IC 4-12

Apple IC 4-12 is a clonal rootstock developed at the Experimental Horticulture Station in Criuleni, Moldova, specifically for growing pear trees. This rootstock features a medium-sized, upright growth habit, which facilitates agricultural management and crown formation. High rooting capacity allows for up to 17 standard grafts per bush, while low branching simplifies plant care. The rootstock demonstrates good winter hardiness and drought resistance, rated 7 out of 10, ensuring reliability in various climatic conditions. IC 4-12 is well-compatible with popular pear varieties such as 'Conference', 'Williams', 'Abat Fetel', and 'Bere Bosk'. It promotes the development of trees with moderate growth vigor and compact crowns, ideal for intensive horticulture. Early fruiting allows gardeners to harvest sooner, and stable productivity persists over many years. Fruits grown on this rootstock exhibit large size, vibrant color, and improved flavor. IC 4-12 is adapted to various soil types, especially thriving on well-drained, fertile soils with neutral or slightly acidic pH. It possesses some resistance to root rot, reducing the need for chemical protection, though preventive treatments against scab and powdery mildew remain essential for maintaining plant health. Due to its characteristics, IC 4-12 is a promising choice for gardeners aiming for high yield and quality of pear crops.
