Cyanogens and Linamarase Activities in Storage Roots of Cassava Plants from Breeding Program

Storage roots of cassava clones arising from six crosses between cassava varieties of different cyanogen levels were analyzed for total cyanogen content and linamarase ( β -glucosidase) activity. Total cyanogen content for 113 clones ranged from 120 to 1941 mg HCN equivalent/kg roots dry wt., the me...

Description
Summary:Storage roots of cassava clones arising from six crosses between cassava varieties of different cyanogen levels were analyzed for total cyanogen content and linamarase ( β -glucosidase) activity. Total cyanogen content for 113 clones ranged from 120 to 1941 mg HCN equivalent/kg roots dry wt., the mean± S.D. being 666±387 mg HCN equivalent/kg roots dry wt. Among these, eight clones exhibited low cyanogen content (mean value
