Determination of Phosphorus Content in 350 Cassava Tuberous Roots Starch

[Objective]A large number of differences species (lines) were selected for high-phosphorus germplasm breeding and researching of the cassava root starch. [Method]The cassava root starch phosphate content of 350 cassava varieties (lines) in the national field cassava gene bank were determined through molybdenum-antimony anti-spectrophotometric method. [Result]The study showed that average phosphorus content in 350 cassava tuberous roots rtarch srrived at 0. 071 046%. [Conclusion]The study provided theoretical basis for the selection of high-phosphorus cassava root starch.
