6个食用型木薯新品种引进筛选与品质鉴定

    Introduction and Screening of 6 New Varieties of Edible Cassava and Their Quality Identification

    • 摘要: 为加大食用木薯新品种的示范推广,丰富漳州市漳浦县薯区品种结构,促进木薯产业的发展。以SC8229、沙田面包、水果木薯、SC1424、SC6068和SC9(CK)食用型品种为材料,在漳州市漳浦县马坪镇进行试验种植,通过对其农艺性状和产质量的观察与测定。结果表明:参试品种适应性好,农艺性状优良;水果木薯、SC6068和SC1424鲜薯产量表现突出,每667 m2产量分别达到4.90、4.20和3.83 t,均比对照增产,增产幅度均达极显著水平;SC6068鲜薯块根干物率含量40.66%,干物率含量比对照高,差异达极显著水平;SC6068块根淀粉含量29.84%,淀粉含量比对照高,差异达极显著水平;SC6068、水果木薯、SC1424和SC9等品种表现出块根产量高或淀粉含量高的优良特性,可在本薯区进一步试验与推广。

       

      Abstract: In order to increase the demonstration and popularization of new varieties of edible cassava, enrich the variety structure in Zhangpu County of Zhangzhou and promote the development of cassava industry, the edible varieties of SC8229, Shatian bread, fruit cassava, SC1424, SC6068 and SC9 (CK) were planted in Maping Town of Zhangpu County in Zhangzhou, and their agronomic characters and yield and quality were observed and measured. The results showed that the tested varieties had good adaptability and good agronomic characters. The fresh cassava yield of fruit cassava, SC6068 and SC1424 was outstanding, with the yield per 667 m2 reaching 4.90, 4.20 and 3.83 t, respectively, which were all higher than that of the control group, with the yield increasing rate reaching extremely significant level. The dry matter ratio of SC6068 tuberous root was 40.66%, which was higher than that of the control group, with the difference reached an extremely significant level. The starch content of SC6068 tuberous root was 29.84%, which was higher than that of the control group, with a significant difference. The varieties of SC6068, fruit cassava, SC1424, and SC9 showed good characteristics with high yield of tuberous root or high starch content, which could be further tested and popularized in the region.
