Abstract: The aim is to clarify the effect of main agronomic traits on pigment yield of Yunnan red radish by analyzing 10 hybrid combinations with correlation analysis, partial correlation analysis, path analysis and principal component analysis. The root length, root diameter, plant height, development degree, leaf weight, leaf length, leaf width, exposed length, single root weight, pigment content of fleshy root and pigment yield of fleshy root were investigated in the harvest period of radish. DPS software was used to conduct the analysis. The variation coefficient of the 11 agronomic traits measured ranged from 0.09% to 10.42%, among which the variation coefficient of development degree was the largest, followed by that of leaf weight; and root weight, pigment content and root diameter were the most important economic characters affecting the pigment yield of Yunnan red radish hybrid combination. On the basis of proper development degree, leaf size and exposed length, the combination of thick root, long root and single root weight should be selected, which is easier to achieve the goal of breeding Yunnan red radish with high pigment content.
