Abstract
Noug Guizotia abyssinica (L. f.) Cass is an ancient and underutilized oilseed. In Ethiopia it is among the most important oilseed in terms of area coverage, volume of production and the main source of edible oil for local consumption. Determining the genetic diversity is fundamental in any noug improvement program. The objective of this study was to find out the extent and pattern of genetic diversity among noug genotypes. The experiment was carried out at Holetta, Ethiopia from June to December 2017 using 98 accessions and two improved varieties. The treatments were arranged in 10 x 10 simple lattice designs. Analysis of variance and variance components were estimated using SAS 9.3. The analysis of variance revealed significant difference (p < 0.05) among the genotypes for all the traits. The highest phenotypic coefficient of variation (78.8) was observed for number of heads per plant. Genotypic coefficient of variation ranged from 2.6 for yield per plot to 72.3 for number of heads per plant. The highest broad sense heritability (90.1) was observed for oil content and the lowest value (37.5%) noted for number of primary branch. The genetic gain ranged from 3.8 for yield per plot to 136.7 for number of head per plant. The study indicates the presence of genetic variability among the tested genotypes which implies the possibility for future improvement and the need for the initiation of a planned breeding and conservation programs by considering all growing areas as important source of desirable traits.
