Arrowroot (Maranta arundinacea L.) is a widely cultivated tuber crop for its easily digestible starch which finds use in the ayurvedic system of medicine as well as in the area of food industry. It has been widely distributed throughout the tropical countries. In spite of its varied economic importance, studies on the association of agronomic characters in the crop are very scanty. In this background, a study on the association of fourteen morphological and yield contributing characters of Maranta arundinacea was carried out in the Genetics and Plant Breeding Division, Department of Botany, University of Calicut, Kerala, India. Among the 14 characters studied, 9 characters were identified as having maximum influence on growth and yield of arrowroot.
