Abstract:
Fenugreek is multipurpose plant originated in the Mediterranean region. Lack of information on phenotypic characteristics is main problems in fenugreek production. Field experiment was conducted at Jamma district of South Wollo, Amhara National Regional State in 2018-19 main rainy seasons to estimate genetic variability, heritability in broad sense, genetic advance, among Ethiopian fenugreek genotypes. Sixty two nationally collected fenugreek genotypes along with standard and local checks were evaluated in simple lattice design. Analysis of variance showed the presence of significant (p< 0.05) difference among genotypes for most of the traits examined, indicating the presence of genetic variability. Seed yield ranged from 651 kg ha-1 to 2148 kg ha-1.A total of 30 and 35 genotypes had yield advantage up to 85 % and 98% than local and standard checks respectively. Seed yield ha-1 and biomass yield ha-1 were characterized with high GCV (29.3, 23.5), PCV (30.7, 27.5), h2 (90.7, 72.3) and GAM (57.6, 41.2). Days to maturity showed the lowest GCV (0.8), h2 (2.3) and GAM (0.3); while the lowest PCV was recorded for days to flowering (4.7).
