Merton Glory Sweet Cherry
Pollination & Compatibility Guide

Merton Glory is a celebrated English white-fleshed sweet cherry bred at the John Innes Horticultural Institute in Merton during the 1930s from a cross of Ursula Rivers × Noble. It produces exceptionally large, heart-shaped cherries with pale cream-yellow skin overlaid by an attractive bright crimson blush. The flesh is tender, juicy, and sweet with a mild, aromatic flavour, making it a standout selection for direct-market growers and estate orchards seeking high fresh-eating quality.

Genotypically, Merton Glory carries the S4S6 allele combination, placing it squarely in Incompatibility Group XVII. Because it possesses the gametophytic self-incompatibility mechanism, it is self-sterile and cannot set fruit with its own pollen or with other Group XVII selections. However, its S4S6 genotype makes it cross-compatible with most traditional commercial cultivars, including Group I (S1S2), Group II (S1S3, such as Van), and Group III (S3S4, such as Bing or Merchant), as well as universal S4′ donors like Stella, Lapins, and Sunburst.

Merton Glory blooms in mid-spring (Bloom Group 3), coinciding reliably with the peak flowering window of many mid-season sweet cherries. Trees are moderately vigorous with an open, spreading growth habit that encourages fruitful spur formation. While productive, its delicate, thin skin makes the fruit susceptible to rain cracking and bird damage near harvest, requiring diligent canopy protection and prompt handling to capture top packouts.
