THE NECTAR RASPBERRY, RUBUS IDAEUS X RUBUS ARCTICUS - A NEW CULTIVATED PLANT
The nectarberry flavour was strongest in an individual of the F3 generation, which received the name 'Merva'. Unfortunately, its yield was so poor that it could not be commercially introduced for general cultivation. However, a cross between 'Merva' and the raspberry variety 'Malling Promise' provided promising selections, one of which was put on sale in 1975, under the variety name of 'Heija'. Both vegetatively and from the point of view of cultivation, its properties are very similar to those of the raspberry, whereas the qualitative composition of its aroma greatly resemples that of the nectarberry.
