糖用甜菜根部性状表现型的规律性分析

通过对42个不同类型和不同来源糖甜菜品种根部性状的数据收集整理、初步分析,进一步了解掌握、并明确了各类型品种在表现型上的差异,试验结果表明：含糖率与根体的某些性状存在一定的联系,如糖用甜菜相对于其它类型甜菜（饲料甜菜、食用甜菜和叶用甜菜）的含糖高,所以根体形状大多表现楔形、圆锥形;根体表皮比较粗糙;肉质比较粗;根沟较深等;各品种间最明显的差异主要表现在根体的长短、长宽比、露出地面的高度和青头大小上.但要明确是哪一个具体品种,必须通过DUS测试的综合指标来加以区别和鉴定.

Regularity Analysis of Sugarbeet Root Traits Phenotype

The data from 42 different sugarbeet varieties of root traits was analyzed to test the differences in the phenotype. The results showed that： there was a certain correlation between the sugar content and some traits of root body, such as conical shape of sugarbeet root; rough root skin and fleshy; deep root groove. The most obvious difference among the varieties was the root length, ratio of length to width, root outcrop height and root tip. However, it was need for using DUS test to identify them.
