Eight Potato Germplasm Resources Based on Principal Component Analysis Experimental Research
In this project,a total of eight potato planting areas were selected as research materials in Yulin,Leshan,Changzhi,Xingxian,Datong,Qixian,and Ulanqab.After drying and crushing,the contents of dry matter,starch,soluble protein,carotenoids,total flavonoids and total phenols were determined,and the differences in the nutrient content of potatoes grown in eight regions were compared,and the effects of environment,soil and planting conditions on the nutrient content of potatoes in different regions were analyzed.The results showed that the nutrient content of potatoes planted in different environments was different,the contents of dry matter and total flavonoids in Yulin were the highest compared with those in the other seven regions,the contents of starch and soluble protein in Ulanqab in Inner Mongolia were higher than those in the other seven regions,the content of carotenoids in Datong potato in Shanxi Province was higher than that in the other seven regions,and the total phenol content of potatoes in Changzhi in Shanxi Province was higher than that in the other seven regions.By analyzing the differences in the nutrient composition of potatoes in different planting areas,it provided a reference for planting high-yield and high-quality potatoes and potato food processing industry.
