| Abstract:
The Pacific northwestern region of North America is known for production of raspberries for process markets. The industry is characterised by being highly mechanised and utilising latest technologies for growing, freezing and processing fruit. For developing new commercial cultivars, high machine-harvested yield is a key objective for this process crop but breeding for this is difficult. In this paper we summarise a recently developed strategy for breeding for high machine-harvested yield based on plant yield components. For high-yielding floricane-fruiting raspberries that ripen early in the season, breeders should place selection emphasis on large berry weight and high numbers of laterals while for late-season ripening, selection emphasis should be on long laterals and long cane length. | |
