| Abstract: |
| The purpose of this study was to comprehensively analyze and evaluate the multi\|trait factors of high generation varieties in aspect of new potato variety breeding. The breeding software (HIDAP) developed by the international potato center was used. The yield, total number of potato tubers and marketable tubers rate for 14 potato high generation strains of multi\|point test in five sites of Dingxi City were analyzed using the analysis of variance significance, AMMI model, the GGE-biplot and Tai stability in 2020. In the AMMI analysis diagram, the IPCA absolute values of yield, the number of tubers per plant and marketable tubers rate of high\|generation varieties 0934-62 in the vertical direction were small and close to the right in the horizontal direction. Combined with the GGE biplot, the high\|generation varieties 0934-62, 1026-2 and 14137-20 were in the higher position above the horizontal line, and the high\|generation variety 0934-62 was the farthest distance above the horizontal line. In the Tai model analysis, the αi and λi parameter distribution range of yield, the total number of potato tubers and marketable tubers rate of high\|generation varieties were combined, and the varieties with high stability were 0934-62, 1026-2 and 1281-191. The results showed that among the 14 potato strains tested, the high generation variety 0934-62 had an outstanding performance in aspect of yield, the total number of potato tubers and marketable tubers rate. High generation varieties 1026-2, 1281-191 and 14137-20 showed better performance, while the high generation variety 1205-5 showed poor yield and stability compared with other varieties. HIDAP software effectively helped breeders manage a large amount of breeding material information, conduct analysis and screening, and timely eliminate through its own evaluation system and use of multiple data analysis models, to reduce the costs and save experimental resources. |
