Independence

Independence originates from the USA, where it was developed in 1965. at the Research Center in Fresno, California, under the USDA breeding program by the well-known breeder J. H. Weinberger. Due to its unique, luxurious, and rich flavor, exceptionally firm flesh, and attractive bright red appearance, it regularly achieves top scores in global quality trials and is considered one of the most profitable yellow-fleshed summer nectarine varieties.

It is a fully self-fertile variety. It is characterized by a very high level of self-pollination and abundant flowering every year, so it reliably and stably bears even in pure single-variety orchards without other pollinators in the orchard. It is an excellent universal pollinator for all other peach and nectarine varieties that flower at the same time. It flowers from medium-early to medium-late and is characterized by small, dark red, bell-shaped flowers whose buds and wood are genetically highly resistant to low winter temperatures and late spring frosts.

The tree is moderately to highly vigorous, with strong scaffold branches that form a well-branched, regular, orderly, and moderately dense canopy, allowing excellent ventilation and sunlight exposure of the fruit. It enters the fruiting stage very early, as early as the second year after planting, and produces abundant, regular, and stable yields with standard agricultural practice. Due to its tendency toward abundant fruit set, mandatory strong winter pruning is required, along with mandatory hand thinning of the fruit in early summer, in order to prevent fruit size reduction.

It belongs to the group of medium-early summer nectarine varieties. In our region and under continental climatic conditions, it ripens at the end of July, usually between July 20 and 30, a few days before the standard Redhaven peach.

Harvesting takes place at the end of July and in early August. The fruit ripens fairly uniformly on the tree and tolerates remaining on the branch after full maturity very well, without dropping, which enables stable harvest planning.

It has excellent storage ability for a summer nectarine. In cold storage, it can be successfully kept for 7–14 days. Due to its very firm, compact, and resilient flesh, it tolerates picking, rough mechanical sizing, packing, handling, and long-distance transport perfectly, making it exceptionally profitable for commercial cultivation and global export. It is primarily intended for luxury fresh table consumption on domestic and foreign markets.

The fruit is medium-sized to large, with an average weight of around 140–160 g, while with excellent agricultural practice individual fruit can reach over 180 g. It is uniform and attractive in shape, elongated-oval, with a weakly pronounced longitudinal groove. The skin is thin, smooth, glossy, and almost completely, over 80–90%, covered with an intense, attractive bright dark red color over a golden-yellow ground color. The flesh is intense yellow-orange, with slight redness around the stone, very firm, compact in texture, and very juicy. The taste is outstanding, full, and distinctly rich, characterized by high sugar content perfectly balanced with pleasant, fine refreshing acidity and a rich varietal aroma. It belongs to the group of true freestone nectarines: the stone is medium-sized and, at full maturity, separates from the flesh completely easily, smoothly, and cleanly.

It is moderately resistant to diseases. It shows excellent natural resistance of the wood to winter cold. On the other hand, it is susceptible to peach leaf curl, Taphrina deformans, and highly susceptible to bacterial leaf and fruit spot, Xanthomonas, which requires mandatory, professional, and regular preventive chemical protection, including copper-based blue spraying during dormancy and at bud break, as well as targeted fungicides throughout the growing season.

Our nectarine fruit trees are produced on highly compatible, certified rootstocks: vineyard peach seedling, an excellent standard for well-drained, light, and moderately fertile soils, and the modern vegetative rootstock St. Julien A, which successfully controls tree vigor on heavier and wetter soils, ensuring a perfect and long-lasting graft union.
