Abstract:
Twenty genotypes of cassava from ICAR-CTCRI were used to study the relation of root traits with nitrogen use efficiency following the Randomized block design (RBD) experimental set up. Association studies were carried out for 9 characters which covers, number of nodal roots, number of basal roots, number of storage roots, number of adventitious roots, length of roots, weight of storage roots, weight of basal and nodal roots, nitrogen use efficiency and tuber yield per plant. Significant positive correlation was observed for characters, number of basal roots, weight of basal and nodal roots, length of roots and number of adventitious roots with nitrogen use efficiency. Path analysis revealed that the characters, weight of basal and nodal roots, weight of storage roots, number of adventitious roots, length of roots and number of nodal roots had a direct effect on dependent character, nitrogen use efficiency.
