Some measures of gene diversity analysis on land race populations of Ethiopian barley

摘要: 158 land race populations of cultivated barley, represented by 3266 individuals from 19 diverse regions composed 72 areas, were assayed electrophoretically for 5 enzyme loci (Est-A, Est-B, Est-C, Est-D and Acph-·l) to determine isozyme variability within among populations. Differences in frequency phenotypes observed between regions. The number allozymes detected the five studied Est-A, 4 6 Acph-·l locus. supply alleles varied region region, area locality locality. Populations same differed their allelic composition. highest a was 22 lowest, 7. A high null at Est-B locus two 44.85% total gene diversity found be due genetic variation localities, 20.13% localities 18.71% areas regions, while 16.31% magnitude contribution different components hierarchy region. No correspondence geographical distance heterozygosity. For computed Nei's Gregorius' logics not give synonymous result. significant heterogenous distribution polymorphic events over observed.
