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.
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。
Therefore, the relative total dry weight of rice would be an important evaluation or screening index for the low P tolerance ability of rice at its seedling stage.
因此，水稻相对单株干重可以作为苗期筛选水稻耐低磷基因型的一个筛选指标。
