Validation of SSR markers linked to oil content in groundnut (Arachis hypogaea L.)

A set of 14 SSR markers that are specific for six QTLs for oil content reported by various authors was selectedfor validation in the present study. The F4:5 mapping population of the cross ICGV 00440 x ICGV 03128 was usedto validate the markers as well as QTLs specific for oil content. Among the selected markers, six markers werepolymorphic for the parents ICGV 00440 and ICGV 03128. Among the six polymorphic SSR markers, two markersIPAHM103 and PGS16F10 revealed a strong association for oil content with a PVE of 15.3 and 19.6 respectivelyin single marker analysis. Validation of QTLs was also performed through composite interval mapping analysis. AQTL with flanking markers IPAHM103 and PM36 could be considered as a potential tool for marker assistedselection of the trait oil content in groundnut.
