BREEDING SELF-SUPPORTING FALL-CROPPING RED RASPBERRIES
Existing germplasm in red raspberry (Rubus ideaus L.) clones of the Oregon-USDA breeding program carries characters for a short, sturdy, branching, fall-cropping type. Two complementary genes are suggested for the control of branching. Certain parents producing early season fall-crop flowering do not always have sturdy branching types in their progeny. Sturdy branching types that are fall-cropping and early in season have been selected for future breeding.
