摘要：

本研究旨在筛选出适宜川西高原地区种植的不同熟期马铃薯品种。通过对18个不同熟期马铃薯品种的12个产量与营养相关性状进行分析，结合多元线性回归和相关性分析对马铃薯的产量和品质进行综合评价。结果表明，早熟品种中单株结薯数、平均单薯重和维生素C含量的变异系数超过30%，早熟品种中产量与主茎数、商品薯率与平均单薯重呈极显著正相关，商品薯率与单株结薯数和维生素C呈显著负相关。中晚熟品种中主茎数、维生素C和还原糖含量的变异系数超过30%，中晚熟品种中商品薯率与平均单薯重呈极显著正相关，生育期与株高、淀粉和还原糖呈显著负相关。本研究初步明确了早熟品种产量与主茎数、单株结薯数和商品薯率相关，而中晚熟品种产量与商品薯率和单株结薯数相关，该结论可为川西高原地区马铃薯品种选育提供参考依据。

Abstract:

To select suitable potato varieties with different maturity periods for cultivation in the Western Sichuan Plateau, this study analyzed 12 yield and quality related traits across 18 potato varieties of different maturity periods, and further comprehensively evaluated their performance of yield and quality by combining multiple linear regression and correlation analysis. Our results showed that in early-maturing varieties, the variation coefficients of the number of tubers per plant, average single tuber weight, and vitamin C content were more than 30%, yield was significantly positively correlated with the number of main stems, and commodity potato rate was significantly positively correlated with average single tuber weight. There was a significant negative correlation between the commodity potato rate and both the number of tubers per plant and vitamin C content. In mid-late-maturing varieties, the variation coefficients of the number of main stems, vitamin C, and reducing sugar content were more than 30%, the commodity potato rate was significantly positively correlated with average single tuber weight, while growth period was significantly negatively correlated with plant height, starch, and reducing sugar content. This study clarified that the yield of early-maturing varieties was related to the number of main stems, number of tubers per plant and commodity potato rate, while the yield of mid--late-maturing varieties waas related to the commodity potato rate and number of tubers per plant. These findings provided a reference for screening and breeding of potato varieties in the Western Sichuan Plateau.
