Origin: in Invergowrie, Scotland, by D.L. Jennings and R.J. McNicol, Scottish Crop Res. Inst. Malling Delight × SCRI 7331/1 (SCRI 703/36 × Glen Prosen); cross made in 1975; tested as SCRI 7518E6; introd. in 1990, marketing rights held by R.W. Walpole, King's Lynn, Norfolk, U.K. Tree: high yielding; early to midseason; spine-free; moderate vigor; long, strong fruiting laterals. Plants not containing gene L1 can be identified in vegetative stage by smaller stipules and less serrated leaves. Gene A1 gives resistance to two strains of the European aphid vector of the raspberry mosaic virus complex; susceptible to raspberry bushy dwarf virus by graft inoculation and probably by pollen transmission. Fruit: very large size due to presence of gene L1, which is unstable; conic; firm; slightly pale color; excellent flavor; freshmarket use.
