Title: īGlen Moy` Red Raspberry
Author: D. Jennings
Since its release from the Scottish Research Institute in 1982, 'Glen Moy' has rapidly become the leading cultivar for early fruiting in Europe and the cultivar most frequently chosen for all new plantings in Britain.
British raspberry growers, particularly those in Scotland, have always preferred cultivars that crop early, partly because the raspberry season is later than in many other production areas.
Hence, 30 years ago the most widely grown cultivars in Britain were Mailing Promise' and 'Mailing Jewel,' this was followed by 'Glen Clova' and it is now 'Glen Moy'; these were all the earliest cultivars available.
On average, 'Glen Moy' was two days earlier than 'Glen Clova' in a Scottish trial (1). Recently growers in Holland and France have realised the considerable market requirement for very early raspberries, and have devised means for producing early fruit under protection some two months before field production starts: 'Glen Moy' suits these methods well.
Indeed, it could be said to be a cultivar which became available in the right place at the right time.
One reason why 'Glen Moy' has replaced 'Glen Clova' so rapidly is the ban on the use of dineseb-in-oil to control excessive vegetative vigour.
The canes of 'Glen Clova' are difficult to manage unless they are chemically burned down in spring but this is not the case for 'Glen Moy.' However, the more important reason for preferring 'Glen Moy' is its much superior fruit quality.
It has an excellent flavor, pleasantly sharp with aromatic over tones; its fruits are uniformly large, typically averaging 3.5 to 4.0gm and appreciably larger than those of 'Glen Clova.' This gives the cultivar a potential for much higher yields.
It is probably the main reason why 'Glen Moy' has usually been top yielder in trials.
The fruits are also firm, have a good shelf-life and an excellent medium redcolor, though without the gloss preferred in parts of North America. 'Glen Moy' and 'Glen Prosen' were
released at the same time and were the first red raspberries to be totally
spine-free, being homozygous for genes, which they have inherited from 'Burnetholm,' a distant ancestor.
They are thus both grower-friendly and picker-friendly, and are particularly popular among pick-your-own growers and amateurs.
