The fruit joins a group of other SCRI-bred raspberries that are named after Scottish glens - Glen Ample, Glen Lyon, Glen Doll and Glen Clova.
The contract to develop Glen Fyne was handled by SCRI's commercial subsidiary, Mylnefield Research Services (MRS).
MRS will also handle licensing and the protection of the variety's intellectual property rights.
Glen Fyne was launched by SCRI's chief executive and director Professor Peter Gregory at the institute's Fruit for the Future event, which was held on 17 July in Invergowrie, near Dundee.
Gregory said: "The launch of this latest variety by SCRI and MRS demonstrates that our partnerships result in products that the public wish to buy and that contribute significantly to the Scottish and UK economy.
"Through these products, knowledge and innovation generated in Scotland reach a global market and Scotland's reputation for biotechnology is enhanced."
Glen Fyne is the latest cultivar to emerge from SCRI plant breeder Nikki Jennings' work. It results from an original cross made by veteran raspberry breeder Derek Jennings before he retired from SCRI in the 1990s.
SCRI's breeding programme is funded by the Scottish Raspberry Breeding Consortium, which is made up of members from the UK raspberry industry with additional funding from the HDC and the Scottish Government's Rural & Environment Research & Analysis Directorate (RERAD).
The berries of Glen Fyne - a mid-season variety, two to three days earlier than Glen Ample at SCRI - are described as round rather than conical in shape.
They are also described as "firm and cohesive" and they plug easily from the receptacle to make it a dual-purpose variety for both the fresh and processing market.
The fruit, like other sister seedlings, is well-presented on strong, spine-free laterals. Machine harvest yield figures extrapolated from SCRI trials are 7.2 tonnes/ha for Glen Fyne - compared with 5.8 tonnes/ha for Glen Ample and 6.2 tonnes/ha for Glen Doll.
Mean fruit size is 4.9g, which compares well with Ample and Doll. Glen Fyne, like Glen Doll, carries the A10 gene, conferring resistance to four biotypes of large raspberry aphid.
