Variability in Storage Root Characteristics and Its Relationship with Yield and Quality of Sweetpotato under Different Environments
Sweetpotato is the most important food and industrial raw materials in the world, which is nutritious, containing a variety of beneficial ingredients. Storage root characteristics include shape, skin color and flesh color of storage root, which have a close relationship with commodity of sweetpotato. Storage root characteristics are visible traits, nutritional qualities are inherent traits. What are the relationship between internal and external traits? The report is rare. In order to study the variability in storage root characteristics and its relationship with yield and quality of sweetpotato under different environments, we chose the hybrids of Xushu 25 and Xu 22-5 as the research object, studied the variation of storage root characteristics in different ecological regions, and explored their relationships with yield and quality. The results showed that storage root characteristics had a wide range of variation in different ecological locations, of which the largest variation was the flesh color, and thesmallest was the skin color. All storage root characteristics were significant differences in genotype, the environmental effect of storage root shape reached to a significant level. Storage root shape strongly influenced by environmental factors, and skin color significantly differenced among the diverse genotypes, while flesh color mainly affected by their inherited characteristic and ecological environment. See from the correlation coefficients, flesh color had highly positive correlation with total carotenoid, reducing sugar and soluble sugar content, significantly negative correlation with starch content. See from the partial correlation coefficients, only the relationship between total carotenoid content and flesh color reached significantly positive, but other partial correlations were not obvious.
