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。
The total root number, the fresh root weight, the dry root weight were mainly controlled by the additive effect, and had higher stable heritabilities.
根系性状中的根鲜重、根干重、根总条数等性状的遗传以加性为主，遗传力高，能稳定遗传，其转育及早代选择有效；
The heritability of dry matter content, number of green leaves and length of vine was higher, weight of fresh tuber, weight of marketable tuber and weight of dry tuber have lower heritability.
广义遗传力以烘干率、绿叶数和蔓长较高，而鲜薯重、大中薯重和薯干重的广义遗传力较低。
After elongation leaf area index was linearly related to ratio index R(760,710), and aboveground fresh and dry weight showed significant relations with ratio index R(1650,1100) in rice.
发现比值指数R（760，710）与水稻叶面积指数呈极显著线性相关；而比值指数R（1650，1100）与水稻地上部鲜质量和干质量均呈极显著幂函数相关关系。
The result of stepwise regression analysis show that the orders are leaf fresh weight, leaf area, petiole length, leaf dry weight, leaf width and leaf length.
方差分析表明，叶长、叶宽、单叶面积等形态指标差异在不同的产地多达显著或极显著水平。
The protein content in leaves was high significantly higher than that in tuber and stem, with stems having lowest level of protein, on the basis of both fresh and dry weight.
结果表明：以干、鲜重为基础的叶片蛋白质含量都极显著高于块茎和茎秆，茎秆含量最低；
The protein content in leaves was high significantly higher than that in tuber and stem, with stems having lowest level of protein, on the basis of both fresh and dry weight.
