Abstract:

In order to comprehensively evaluate the genotype and the interaction of genotype and environment of sweet potato in regional test, the GGE biplot was used to analyze the fresh yield of group 2 of high-quality starch strains in regional test of sweet potato in Fujian from 2020 to 2021. The results showed that: ‘Quanshu 26’ had the best yield performance and had strong adaptability in Zhangpu, Fuzhou, Quanzhou, Putian, Sanming, and Nanping in 2020. ‘Longshu 39’ had high and stable yield, which was the ideal variety of the regional test. In 2021, ‘Jinshu 43’ had the best yield and stability, making it an ideal variety of the regional test. ‘Hongjinshu 2’ had high yield and strong regional adaptability in Ningde, Longyan, Sanming, and Fuzhou. In addition, the Sanming pilot had high discrimination and representativeness in the two-year regional test, and it was an ideal pilot environments. The GGE biplot can intuitively evaluate the yield characteristics of the test strains and the representativeness of the pilots, providing a simple and effective analytical method for objectively evaluating the high and stable yield of sweet potato strains.

Key words: sweet potato, GGE biplot, high yield, stable yield, adaptability, pilot discrimination
