Starch Yield of Potato Varieties:Performance and Stability
The study aims to solve the lack of high starch processing potato varieties with high yield and good quality in Hulunbuir area. In 2022 to 2023,using'Weilasi'as the control,the phenophase and tuber traits of 8 potato varieties were investigated,and the performance and stability of starch content,tuber yield and starch yield were identified and evaluated. Among the 9 cultivars,the starch content of'Zhong Shu 49'and'Long Shu 20'ranked first and second respectively,and the average values of the two years was 18.27 and 18.10 respectively,which were higher than those of the control,but the difference was not significant.'Long Shu 20' and'Zhong Shu 28'had high tuber yield of 55074 kg/hm2 and 54607 kg/hm2 respectively,which were significantly higher than that of the control,and the stability was good. The highest tuber starch yield of'Long Shu 20'was 9863 kg/hm2,which was significantly higher than that of the control and other cultivars,and the performance was stable.'Long Shu 20'had the highest starch yield and stable performance among the nine cultivars,which was suitable for demonstration and promotion as a starch processing variety in this region.
