Kodo millet (Paspalum scrobiculatum L.) is an important nutri-cereal. Gujarat, a Western state in India with favorable edapho-climatic factors may contribute in augmenting kodo millet production if suitable crop improvement programme is implemented. Study of character association reveals important yield component traits which could be selected for overall yield enhancement hence in development of better genotypes. In the present investigation, 49 genotypes of kodo millet were evaluated during kharif 2021 for 19 quantitative traits with an aim to identify important yield components. Genotypic (rg) and phenotypic correlation (rp) coefficients were estimated followed by path coefficient analysis. The study revealed that direct selection based on harvest index and fodder yield per plant may help in augmenting grain yield as the traits had strongest positive association and maximum direct effect on grain yield per plant. Crude protein content (%) and plant height appeared to be most important characters for indirect selection.
