Abstract

Aim: The aim of this study was to determine the nature and strength of association between yield and yield related traits as well as to obtain information on path coefficient for yield and contributing traits.

Materials and Methods: The experiment was conducted in central Ethiopia during main cropping season at two locations (Bishoftu and Akaki) and arranged in 7x7 simple lattice designs. The planting material consisted of 49 tef recombinant inbred line along with standard check.

Results: Number of primary panicle branches per main shoot, above ground biomass and harvest index had a positive direct effect on the grain yield at both phenotypic and genotypic levels. According to path coefficient analysis, above ground biomass, harvest index, number of spikelets per panicle and number of florets per spikelets are the primary component traits affecting grain yield. Grain yield and other yield related traits have significance positive correlation.

Conclusion: It was concluded that above ground biomass and harvest index had highest positive direct effect on grain at both genotypic and phenotypic levels and direct selection of genotypes with high mean values of above ground biomass and harvest index to increase tef yield is important in tef improvement program.
