Abstract

A mapping population consisting of 146 Recombinant Inbred Lines obtained from the cross TG 26 x GPBD 4 (F9 generation) was used in order to identify microsatellite markers/QTLs associated with foliar disease resistance, nutritional quality and productivity traits. Phenotyping for various traits viz., rust (three stages), late leaf spot (LLS) (two stages), protein and oil content, eight fatty acids (Palmitic, stearic, oleic, linoleic, arachidic, eicosenoic, behenic and lignoseric fatty acids), four derived traits for fatty acids (O/L ratio, Iodine value, U/S ratio and %S), two agronomic (Plant height and number of branches) and four productivity traits (no. of pods, pod yield, shelling % and 100-seed weight) were carried out in five different seasons (Rainy 2005, 2006, 2007 and Post-rainy 2007 and 2008) at U.A.S., Dharwad. Parental screening (1043 SSR primers) and genotyping of 53 polymorphic markers for the mapping population was carried out at ICRISAT, Patanacheru, Andhra Pradesh. Phenotypic and genotypic data were subjected statistical analyses for establishingmarker-trait association....
