相对遗传进度以根产量为最大，其次为褐斑病发病级数；
果肉厚度和果实干、鲜重的相对遗传进度较高，通过较少次的选择可得到有效的提高。
The relative genetic progress of fruit flesh thickness, fruit dry weight and fruit fresh weight was higher, which could be improved efficiently by fewer generation selections.
在5%的选择强度下，所有性状的相对遗传进度在25.2 ~ 48.69%之间，有较大的选择潜力。
Under 5% intensity of selection, the relative genetic progress of all traits is between 25.2 ~ 48.69%, which means more selection potential.
