Abstract
Red raspberry (Rubus idaeus L.) has been grown in the north of Extremadura in Spain for more than three decades, mainly in the regions of La Vera, Valle del Jerte and Sierra de Gata, both in greenhouses and outdoor orchards.
Over the last decade, new cultivars have been established from different breeding programmes; however, many of these modern cultivars are not well adapted to the agro-climatic conditions of these regions.
The lack of firmness or a very dark red fruit colour were the main problems identified.
For these reasons, it was considered appropriate to initiate, in 2015, a breeding programme with the aim of obtaining new cultivars from a modern pedigree with desired traits, specially adapted to this crop area.
In this work we have developed techniques of emasculation and pollination, and have a determined suitable pollen viability medium, in several crosses of commercial cultivars of red raspberry.
