摘要： Groundnut is basically grown for its oil in most countries and the quality of the oil depends on the total oil, protein and fatty acid compositions in the seeds. The objective of this study was to identify markers that were associated with fatty acids, minerals and proximate composition in groundnut seeds. One hundred and seventy groundnut collections were evaluated in the dry season of 2017 at the research field of the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Bayero University Kano. Marker trait association was calculated using the GAPIT package via the KDCompute interface. Significant differences were observed between the genotypes for all the trait measured except for moisture content, crude fiber, crude fat, crude protein, dry matter and nonadenic acid. The heritability values of traits ranged from 0.04 to 0.48. A total of 144 highly significant (P<0.001) MTAs with 46 markers for fatty acids (118), minerals (4) and proximate (22) compositions were identified. Most of the markers identified possible MTA in both the A and B genomes. Validation studies are needed to find if these markers are identifying one locus or perhaps a locus duplicated in the two genomes.
