Chuhong has high germination rate and strong branching ability. Strong fruiting ability, high and stable yield. Chuhong has a strong flowering ability, and the fruiting branch rate is about 85%, mainly long fruit branches. Long fruit branches account for 77% of the total fruit branches, and the fruit setting rate of each long fruit branch is above 95%. Start early and bear fruit early.
