In: South Indian HorticultureSummary: Se emprendio un estudio de correlacion detallado para 1) determinar la relacion de la antocianina con los niveles de cianuro en las raices de yuca y 2) evaluar la interrelacion en cuanto a la distribucion de HCN entre hojas, peciolos y raices. Se utilizaron 45 genotipos de yuca, incluyendo hibridos y accesiones exoticas e indigenas mantenidas en el Central Tuber Crops Research Institute (Trivandrum, India). La concn. de glucosidos cianogenicos presentes en varias partes de la planta vario ampliamente entre genotipos. En todos los genotipos, las hojas presentaron las concn. mas altas de HCN y la cantidad de HCN en las raices y peciolos se correlaciono significativa y positivamente con el HCN foliar. Aunque el contenido de antocianina de los peciolos presento una relacion negativa con el HCN radical, el valor R(2) es muy bajo. Los resultados sugieren que se puede estimar el potencial de HCN de las raices de yuca con base en el nivel de HCN foliar. (RA-CIAT)Summary: A detailed correlation study was undertaken to (1) determine the relationship of anthocyanin with cassava root cyanide levels and (2) test the interrelationship for the distribution of HCN among leaf, petiole, and root parts. Forty-five cassava genotypes, comprising hybrids and exotic and indigenous accessions maintained at the Central Tuber Crops Research Institute (Trivandrum, India), were used. The concn. of cyanogenic glucosides present in various plant parts varied broadly among the genotypes. In all the genotypes, the leaves contained higher HCN concn. and the amount of HCN present in the roots and petioles was significantly and positively correlated with leaf HCN. Though the anthocyanin content of the petiole showed a negative relationship with root HCN, the R(2) value is very low. Results suggest that the HCN potential of cassava roots can be predicted based on leaf HCN status. (AS)
