Association mapping of seed oil and protein content in Sesamum indicum L. using SSR markers.

ABSTRACT: Sesame is an important oil crop for the high oil content and quality. The seed oil and protein contents are two important traits in sesame. To identify the molecular markers associated with the seed oil and protein contents in sesame, we systematically performed the association mapping among 369 worldwide germplasm accessions under 5 environments using 112 polymorphic SSR markers. The general linear model (GLM) was applied with the criteria of logP ≥ 3.0 and high stability under all 5 environments. Among the 369 sesame accessions, the oil content ranged from 27.89%-58.73% and the protein content ranged from 16.72%-27.79%. A significant negative correlation of the oil content with the protein content was found in the population. A total of 19 markers for oil content were detected with a R2
