Association analysis of agronomically important traits using SSR, SAMPL and AFLP markers in bread wheat

In bread wheat, marker-trait associations were studied for 14 agronomic traits using a set of 519 DNA-based molecular markers (derived from 20 SSR, 2 SAMPL and 8 AFLP primer pairs) with a set of 55 elite wheat genotypes. Using simple linear and multiple regressions, each of the 14 traits was regress...

Description
Summary:In bread wheat, marker-trait associations were studied for 14 agronomic traits using a set of 519 DNA-based molecular markers (derived from 20 SSR, 2 SAMPL and 8 AFLP primer pairs) with a set of 55 elite wheat genotypes. Using simple linear and multiple regressions, each of the 14 traits was regressed on all 519 available polymorphic markers (221 SSR markers, 43 SAMPL markers and 255 AFLP markers). A total of 131 SSR, 43 SAMPL and 166 AFLP markers gave significant associations with at least one of the 14 traits, either with linear or with multiple regression; 51 of these markers showed association using both approaches (linear and multiple regressions), and therefore may prove useful for marker-assisted breeding after necessary validation.
