Abstract

Grain yield is a complex trait which is influenced by several component traits and direct selection for grain yield is often not effective. Thus, it is essential to study the association of yield components with yield. The objective of this study is to evaluate the genotypic association of yield components with yield and their direct and indirect effect on grain yield of tef. Eighteen tef genotypes were evaluated in a randomized complete block design with four replications at Holetta agricultural research center in central highland of Ethiopia. Analysis of variance revealed highly significant genotypic difference for most of evaluated traits. Grain yield had a positive and significant genotypic correlation with panicle length (rg = 0.98), plant height (rg = 0.64) and shoot biomass (rg = 0.53) indicating dependent genetic control between grain yield and these traits. Days to maturity, shoot biomass and harvest index exert favorable direct effects on grain yield. Panicle length, shoot biomass and plant height could be used as target traits to improve tef grain yield because of their significant genotypic correlations with grain yield and favorable direct and indirect effects via the other yield attributing traits.
