Abstract

Abstract:

To understand the characteristics of local potato germplasm resources and screen out excellent materials in Zhejiang Province, 13 qualitative traits and 6 quantitative traits of 95 potato germplasm resources collected in the Third National Agricultural Germplasm Census and Collection Action of Zhejiang Province were investigated and analyzed in 2019-2020. The results showed that the phenotypic genetic diversity of the local germplasm resources was relatively rich. Shannon-Wiener diversity index of quality traits ranged from 0.380 to 1.686, of which the diversity index of viral diseases was the highest, indicating that these germplasm resources were with different degrees of viral degradation. The diversity index of flavor was the lowest, and there were 88 germplasm resources with good flavor, accounting for 92.63%. The average diversity index of the 10 morphological traits was 1.079, of which three traits of tuber shape, flesh color and corolla color showed the most abundant diversity. The diversity indexes of the six quantitative traits were high, with an average of 2.84, and the tuber yield and number of main stems were particularly prominent. The tuber dry matter contents of the germplasm resources varied from 18.1% to 25.8%, of which 73 resources with dry matter content ≥ 20%, accounting for 76.84%. The 95 germplasm resources could be classified as small potato germplasm (62 resources), medium and large potato germplasm (21 resources) and colored potato (12 resources). All small potato resources were yellow tuber skin and flesh, high dry matter content and good cooking flavor. Nine excellent resources were screened and could be used for production and breeding.

Key words: potato, germplasm, phenotypic diversity
