Leaves are dark green, the back of the leaf has velvet hairs, the leaf surface is shallowly folded, the edge of the leaf is finely serrated, and the tip of the leaf is downward. Disease resistance is average, cold resistance is strong, the yield is about 750-1500 kilograms per mu, suitable for large area development.

Yellow raspberry: strong, sprouting power, branching power, basal branches less, fruit flavor, loved by consumers. Leaves light yellow-green, the back of the leaf has hairy, with a small number of short spines, the leaf surface folds deeper, the leaf edge serrated fine, leaf shape is more pointed, the tip of the leaf down. Cold and disease resistance is strong. Higher yield, 1000-1500 kilograms per mu. Soil requirements in general, do not like too high fertility of the soil, suitable for matching varieties cultivation or large area development.

Black raspberry: strong growth, strong sprouting branching power, fewer basal branches. Leaf surface dark green, the back of the leaf gray-white and with hairy. Leaf margins are finely serrated, and the tips of the leaves are pointed downward. Disease resistance and cold resistance, low yield, 400-750 kilograms per mu.
