Selection Index for Improving Grain Yield and Related Traits in Tef (Eragrostis tef)
Selection indices provide useful information to breeders who usually base selection on means and ranks. Knowledge on selection criteria for improving tef grain yield is very limited. Accordingly, the objective of this study was to develop selection criteria for improving tef grain yield through indirect yield component selection via a selection index. Different trait combinations along with thr...
متن کاملInterrelationship and path coefficient analysis of yield components in F4 progenies of tef (Eragrostis tef).
This experiment was conducted at Debre Zeit and Akaki during 2004-2005 cropping season on F2-derived F4 bulk families of three crosses, viz, DZ-01-974 x DZ-01-2786, DZ-01-974 x DZ-Cr-37 and Alba x Kaye Murri. To estimate the correlations and path coefficients between yield and yield components, 63 F4 families were taken randomly from each of the three crosses. The 189 F4 families, five parents ...
متن کاملGenetic diversity in tef [Eragrostis tef (Zucc.) Trotter]
The DNA polymorphism among 92 selected tef genotypes belonging to eight origin groups was assessed using eight inter simple sequence repeat (ISSR) primers. The objectives were to examine the possibility of using ISSR markers for unravelling genetic diversity in tef, and to assess the extent and pattern of genetic diversity in the test germplasm with respect to origin groups. The eight primers w...
متن کاملThe origins and progress of genomics research on Tef (Eragrostis tef).
Tef, Eragrostis tef (Zucc.) Trotter, is the most important cereal in Ethiopia. Tef is cultivated by more than five million small-scale farmers annually and constitutes the staple food for more than half of the population of 80 million. The crop is preferred by both farmers and consumers due to its beneficial traits associated with its agronomy and utilization. The genetic and phenotypic diversi...
متن کاملGenetic and phenotypic diversity in selected genotypes of tef [Eragrostis tef (Zucc.) Trotter
Tef [Eragrostis tef (Zucc.) Trotter] is an important staple food crop, especially in Ethiopia where it is annually grown on 2.8 million hectares of land. It is important for food security in the region, in spite of having a low yield, mainly due to lodging. In this study, 15 representative landraces as well as three improved varieties have been selected for in-depth characterization of many par...
