Sweet Longfield is an apple of Russian origin, with the name adopted in place of the earlier name Kursk Reinette by the Russian Nomenclature Commission [S1]. It was included among ten Russian apple varieties selected for northwestern attention [S1].
The main description gives the fruit as size 5 on the document's scale, oblong and somewhat oblique, yellow with a blush on the sun side and dark dots [S1]. The flavor is described as sweet, and the season is early autumn [S1].
The tree is described as hardy, a good bearer, rather spreading, and having heavier foliage than Longfield [S1]. A later list describes the fruit as large, oblong conic, regular, and with an acute cavity, which differs slightly from the main entry's size and form wording [S1].
