Cultivar 1694: Isham Sweet

Isham Sweet is a Wisconsin apple. A Study of Northwestern Apples describes it as medium sized and roundish, tapering slightly toward one end. The skin is yellowish green, mostly covered with brownish red. The sunny side has solid and mixed color, while the shaded side has broader stripes or splashes. [S1]

The source gives no breeder, parentage, release date, nursery, or testing code. It places Isham Sweet in Wisconsin and includes it in an alphabetical survey of apple cultivars used for northwestern comparison and description. [S1]

The fruit has distinct, numerous russet dots, a regular acute cavity with much radiating russet, and a short stem. The basin is very shallow and minutely wrinkled. The calyx is open, with flat convergent segments. The core is closed, the cells are round and entire, the tube is funnel shaped, the stamens are median, and the seeds are long, large, and flat. [S1]

The flesh is very yellow, veined with yellow, firm, very sweet, and rated very good in quality. The bulletin's classified table also notes that the flesh is very yellow. [S1]

Isham Sweet is listed as a late fall to early winter apple. The packet gives no storage duration beyond that season and no specific culinary uses. The name and description suggest a sweet dessert or utility apple, but the source does not state that use directly. [S1]

The supplied evidence gives no tree habit, productivity, disease behavior, or pruning notes. It also gives no explicit hardiness rating. Its inclusion in a northwestern apple bulletin gives regional evaluation context, but it is not a direct zone claim. [S1]

Taxonomically, Isham Sweet is treated only as an apple cultivar in the Malus cultivar list. The available records give no parentage, sibling relationship, descendant use, or broader breeding role. [S1]
