Mean Performance Evaluation and Variability Estimation in Ethiopian Mustard (Brassica Carinata A Braun) Genotypes

Study of genetic variability is crucial in plant breeding to find traits of interest in genetic resources for any crop improvement. The present study was carried out using 36 genotypes including two checks to evaluate the mean performance of the genotypes, to examine the genetic variability, heritability, expected genetic advance and genetic advance as percent of mean. All the thirty six genotypes were tested using simple lattice design at Holeta Agricultural Research Center during 2018/2019. Observations were recorded on plot basis for days to flowering (days), days to maturity (days), yield per plot (g), yield per hectare(kg), oil yield (kg), oil content (%) and thousand seed weight (g) and on plot basis for plant height (cm). Analysis of variance revealed the significant differences among the tested genotypes for all traits considered. The phenotypic coefficient of variation observed in this study was higher than the genotypic coefficient of variation for all traits considered implying that high influence of environment on those traits. High phenotypic coefficient of variation was observed for all traits and moderate genotypic coefficients of variation recorded by seed yield per hectare, seed yield per plot and oil yield per plot. Low genotypic coefficient of variation was recorded by days to flowering, days to maturity, oil content, thousand seed weight and plant height. The study of genetic advance in this experiment showed high genetic advance for all traits except thousand seed weight which recorded low genetic advance.
