Prolific is a University of Saskatchewan apple from the cross 'Columbia' x 'Wealthy'. It was introduced in 1960 and released by Dr. C.F. Patterson at Saskatoon. [S1] [S2] [S3] [S6] It appears to have been selected as a productive prairie apple with acceptable dessert quality, but not as a long keeper. [S1] [S3] [S6]
Sources describe the fruit as small to medium, usually under 5 cm, or up to about 2 by 1 7/8 inches under non irrigated Saskatoon field conditions. [S1] [S3] [S6] It is somewhat egg shaped or conical, with a greenish to yellow ground color and a light to attractive pink red blush, sometimes with bloom. [S1] [S3] [S6] The flesh is creamy white. The flavor is very mildly sub acid, and sources call it good quality. [S2] [S3] [S6]
It ripens from early to late September, depending on the source. [S1] [S3] [S6] Keeping quality is mixed in the record. One source calls it a fair keeper, while another says it is often too late and does not keep. [S1] [S3] [S6] A prairie index table classifies it for processing use. [S2] A Saskatchewan horticultural note was less favorable and grouped Prolific among varieties said to lack size and or quality compared with better sorts. [S5]
The tree is described as a heavy fruiter with good yield under Saskatoon conditions. [S1] [S3] [S6] The clearest hardiness context here is geographic rather than explicit zone language. It was bred and described at the University of Saskatchewan and appears in prairie testing and cultivar indexes, placing it within the cold climate apple work of the Canadian prairies. [S2] [S3] [S6]
Prolific's documented lineage in this packet is limited to its direct parentage, 'Columbia' x 'Wealthy'. [S1] [S2] [S3] [S6] No later descendant or sibling relationships are given here. Its historical interest lies in its Saskatchewan introduction and in the contrast between strong productivity and a less consistent reputation for fruit size, quality, and storage. [S3] [S5]
