YIELD COMPONENTS OF PRIMONCANE-FRUITING RED RASPBERRIES

Yield components which contribute to high, early yield in primocane-fruiting red raspberries were measured for ‘Heritage’ and three advanced selections from the Minnesota breeding program.
The plots, established in 1979, were mowed in the springs of 1983 and 1984 and data was collected in both seasons.
Yield components which contributed to high yields in ‘Heritage’ in both seasons were high number and percent of nodes fruiting, and higher number of berries per meter row and per cane.
MN 629 in 1983 had a higher cane density than the other genotypes but in 1984, with equal densities, MN 629 had a lower yield.
MN 659 had the largest berry size in both years.
To obtain yields equal to ‘Heritage’, early fruiting primocane-fruiting cultivars will need to have higher cane densities and/or larger berry size to compensate for lack of lateral branch development.
