Latin name of the genus and species of the plant claimed: Prunus persica L. Batsch.

Variety denomination: ‘S 6816’.


The new nectarine tree ‘S 6816’ was developed by the Institut National de la Recherche Argonomique (INRA) at Angers, France, as part of a controlled breeding program. ‘S 6816’ was one of several seedlings resulting from a cross of [(Kiang-Si×Independence)×Summergrand]×Marsun (all unpatented). ‘S 6816’ was asexually propagated by budding at Angers, France, and has been observed to remain true to type over successive asexually propagated generations.


‘S 6816’ was selected for its suitability as a commercial nectarine tree cultivar. Fruit of the ‘S 6816’ cultivar matures in late July in central Washington state, and is notable for its aromatic and sweet yellow flesh. The fruit of ‘S 6816’ is distinguishable from that of the parent varieties by its flat shape and smooth skin. The characteristics which distinguish ‘S 6816’ from its parents are set forth in Table 1.

This variety is distinguishable over related variety ‘S 6817’ (U.S. patent application Ser. No. 10/642,441) by its earlier maturity date and smaller and sweeter fruit.

The following is a detailed botanical description of ‘S 6816,’ a new and distinct nectarine tree, based on observations made during the 2004 growing season, of specimens planted at Parker, Wash., USA, in 1999.

It should be understood that the botanical and analytical characteristics described will vary somewhat depending upon cultural practices and climatic conditions, and can vary with location and season.
