引进甘薯种质资源主要品质性状鉴定评价

摘要

对32份从国际马铃薯研究中心（CIP）引进的资源材料进行主要品质性状评价，结果表明：胡萝卜素含量≥10 mg/100 g鲜样的资源材料9份，薯干黄酮类化合物≥0．9％的资源材料4份，薯干淀粉含量≥60％的资源材料7份，薯干蛋白质含量≥8％的资源材料4份，薯干可溶性糖含量≥17％的材料3份，其中资源Y08-11和Y08-16的胡萝卜素和蛋白质含量均较高，Y08-20的胡萝卜素和淀粉含量均高，Y08-35的胡萝卜素、蛋白质、黄酮类化合物、可溶性糖含量均高。%The major quality characters of 32 introduced sweet potato resource materials from Center of International Potato (CIP) were evaluated.The results showed that there were 9 resource materials containing more than 10 mg/100 g carotene in their fresh tubers, 4 resource materials containing more than 0.9% flavonoids in their dry tubers, 7 resource materials with the starch content of larger than 60%in their dry tubers, 4 resource materials with larger than 8%protein content in their dry tubers , and 3 resource materials with more than 17%soluble sugar content in their dry tubers .Among 32 materials, Y08-11 and Y08-16 had higher carotene and protein content , Y08-20 had higher carotene and starch content , and Y08-35 possessed higher contents of carotene, protein, flavonoids and soluble sugar .
