Stability Analysis and Adaptability Evaluation of Potato Cultivars in Winner Paddy Field
In order to reveal the variation pattern of potato main agronomic traits and screen out the superior cultivars suitable for winner paddy field,six potato cultivars were used as test materials in three years(2018-2021),and main agronomic characteristics were detected and analyzed by variance analysis,correlation analysis and principal component analysis.The results showed that there were different or significantly different among main agronomic characteristics of different cultivars.The year effects and genetic effects of all characteristics were different or significantly different,and the year effects were more than genetic effects,but only the plant height exhibited a greater genetic effects.Correlation analysis indicated that the plant height was extremely significantly positively correlated with single tuber weight,potato weight of per plant,large-medium potato rate and fresh potato yield.The number of main stems was extremely significantly positively correlated with tuber number per plant,but extremely significantly negatively correlated with single tuber weight and large-medium potato rate.Based on principal component analysis,the comprehensive evaluation model for the adaptability of table potato cultivars in winner paddy field were established and two quality cultivars suitable for popularization were screened out.
