Abstract: Twenty seven genotypes including two check varieties (NDC-1 and NDC-2) of taro (Colocasia esculenta L. var. Antiquorum)were assessed to work out the association of different yield traits, direct and indirect effects of their various attributes on yield per plant. The yield per plant had shown significant and positive correlation at phenotypic level with weight of cormels per plant (0.695), number of cormels per plant (0.595), weight of corms per plant (0.451), day to sprouting (0.293). However, this character had negative and significant association with plant height (-0.364), petiole length (-0.303), leaf width (-0.287), leaf length (-0.296). Among other traits days to sprouting had positive and significant association with number of cormel per plant (0.343), yield per plant (0.293), weight of cormels per plant (0.285), at phenotypic level. At phenotypic level weight of cormels per plants (0.543) followed by weight of corm per plant (0.499), number of cormels per plant (0.217), length of leaf (0.183), and petiole length (0.072) exerted high positive direct effect on total yield per plant. Length of leaves had negative and significant association with yield per plant (-0.296) which was mainly due to indirect effects by weight of cormels per plant (-0.130) and width of leaf (-0.121). Petiole length via indirect effects of weight of cormels per plant (-0.149) and plant height (-0.101) was showed negative and significant association with yield per plant (-0.303).
