Current Situation of Colored Potato Varieties and Evaluation of Their Tuber Phenotypic Characters
Based on the analysis of reported and registered color potato stem,leaf color,phenotypic traits,combined with the phenotypic character of F1 generation materials collected by the project team,the color and distribution of anthocyanins in stem,leaves,skin and tuber flesh were described and classified.The analysis showed that the purple or red phenotype of the new leaves on the top of the plant could significantly improve the efficiency of field identification and screening of new colored potato strains in early generation.The classification standard and standardized description of anthocyanin color position in tuber flesh are the key to further study the mechanism of anthocyanin biosynthesis and accumulation,and play a crucial role in the commerciality and economic value of new colored potato varieties.The evaluation of phenotypic traits and color quantification of colored potato tubers are helpful to promote the breeding of new colored potato varieties.
