AZOS-1 rootstock – a grape rootstock included in the breeding program of the Anapa Zonal Experimental Station of Viticulture and Enology. Leaves are dark green, medium-sized, almost entire, five-lobed with a reticulate-veined upper surface. Leaf margins are slightly curved downwards, teeth are sharply triangular, and the lower surface is covered with weak bristly hair along the veins.
AZOS-1 bushes are characterized by high growth vigor and upright shoots. Internode length is 14–15 cm, and the petiole sinus is closed and ovate. The petiole has a weakly cherry color, about 15 cm long, which ensures good cluster structure.
The rootstock is distinguished by resistance to phylloxera (infection degree 2.5 points), chlorosis, and other diseases. Due to high yield of standard cuttings – from 180 to 210 thousand per hectare – AZOS-1 ensures economically viable production. Moreover, the new training system for rootstock bushes with freely hanging shoots increases labor productivity during pruning and cutting preparation, reducing costs in disease and pest control.
Overall, AZOS-1 represents a reliable and productive option for viticulturists, offering a combination of high yield, disease resistance, and ease of use.
