28份甘薯种质的产量和营养及食味评价
Evaluation of the yield, nutritive content and eating quality in sweet potato germplasm containing 28 cultivars
摘要
Abstract
The yield, nutritive content and eating quality of 28 sweet potato cultivars were evaluated in Hainan, China. The results indicated that: ①Cultivars Yanzishu 176, Hainan Heiroushu and Xushu 23 could be considered as promising breeding materials. ②The average fresh root yield, dry root yield and starch yield of purple sweet potato were 62.3%-73.2% of those of the yellow and white sweet potato, but the protein, vitamin C and carotene content of the purple sweet potato were higher than those in the yellow and white sweet potato. ③There was very significantly positive correlation between fresh root yield, dry root yield and starch yield; The fresh root yield was clearly negative correlated with dry matter content and starch content; The dry matter content was very significantly positive correlated to starch content; The soluble sugar content was very significantly positive correlated to dry matter content and starch content; The vitamin C content was very significantly positive correlated to dry matter content, starch content, soluble sugar and protein content; There was no significant relationship between the eating quality and the nutritive yields and nutritive content.关键词
