Other claims from this paper (13)
- Observation Highly significant differences (p < 0.01) were found between all traits, except grain yield (p < 0.05).
- Observation The number of days to 50% flowering ranged from 27 to 71 days across tef genotypes.
- Observation The number of days to 75% physiological maturity ranged from 54 to 94 days across tef genotypes.
- Observation Plant height ranged from 58.1 to 134.5 cm across tef genotypes.
- Observation Panicle length ranged from 20.3 to 49.25 cm across tef genotypes.
- Observation Accessions 244, 794, 18,960, 24,312 and 9,462 showed superior grain yield, with yields of 1.95 to 1.89 t/ha reported.
- Observation High phenotypic and genotypic coefficients of variation were observed for grain yield, culm diameter and spikelets per panicle.
- Observation Broad-sense heritability and genetic advance over the mean were highest for most of the studied traits.
- Association Panicle length and spikelet count were positively correlated with grain yield.
- Observation Days to 50% flowering were negatively correlated with the other traits they were compared with.
- Observation Cluster analysis revealed four groups of traits.
- Observation The first four principal components explained over 81.32% of the variability.
- Recommendation Identifying high-variability genotypes will aid yield improvement through selection and hybridization.
