dc.description.abstract | Tef is an indigenous and major staple cereal crop in Ethiopia. It adapts to a
wide range of environmental conditions and fits to different production
systems. Nineteen released tef varieties were evaluated in a randomized
complete block design with three replications during the 2007/08 offseason
al Dehre Zeit Agricultural Research Center (DZARC). The objectives were
to estimate the genetic variation in grain yield and yield related traits, and
to see the association among traits of released tef varieties under off-season
condition. The analysis of variance showed significant (P<0.01) variation
among the varieties for all traits evaluated except total shoot biomass yield.
The correlation analysis showed positive and significant association of
grain yield with number of fertile tillers (rg = 0.49, rp=0.32), shoot biomass
yield (rg— 0.77, rp=0.71), harvest index (rg = 0.87, rp=0.73') and lodging
index (rg = 0.23, rp=0.10). Days to panicle emergence and to maturity, on
the other hand, have shown negative association with number of fertile
tillers, shoot biomass yield, grain yield, harvest index and lodging index.
The highest means of harvest index and grain yield per hectare were
obtained for the early maturing varieties as compared to the late ones.
Therefore, it is better to use the early maturing varieties (DZ-Cr-37 and Ho-
Cr-136) for o f f - season planting, and double cropping in the central
highlands of Ethiopia. | en_US |
