Yield and Starch Quality of Cassava Cultivars Planted in Jiangxi Province
The fresh root yield and starch quality of 7 cassava varieties SC5,SC6,SC7,SC8,SC9,SC10 and SC205 developed in CATAS were studied in Jiangxi in provine 2008 and 2009.The results showed that the fresh root yield of SC8 was the highest and that of SC5 was the lowest.Starch content of SC6 was the highest and that of SC5 was the lowest.Fresh root yield and starch content of SC8 were significantly higher than those of the control variety SC205,and those of SC5 were significantly lower than the control variety SC205 and the other 5 varieties.Compared with the control SC205,SC8 and SC5 were higher in amylose content,frozen stability,composed qualitative and grace's viscosity,were slightly larger in starch granule size and lower in pasting temperature.Transparency and viscosity of SC205 were higher than those of SC5,but less than those of SC8.The adaptability of SC8 and SC205 in Jiangxi was better than other cassava varieties.
