Genome-wide Association Mapping (GWAS) for Anther Extrusion in Bread Wheat (Triticum aestivum L.) Using DArT-SNP Markers

Abstract

Association Mapping (AM) for anther extrusion trait was done in a sub-set of 190 diverse genotypes of SWRS material grown at University Research Farm and showed a wide range of variation. The growth habit, country of origin and AE (Anther extrusion) scores of all 190 genotype. The range of AE score of the 190 wheat genotypes differ from 0.47 to 2.97 with a mean value of 1.23 and a SD of 0.36 %. In association analysis based on mean values over environments, significant association (p<0.01) of different traits (AE, DTH, DTA, DTM). DTH was observed for a total of 181 DArT SNP marker loci following GLM. Anther Extrusion was observed for a total of 177 DArT SNP marker loci following GLM.
