Title Construction of Genetic Linkagemap and QTL Analysis for Foliar Disease Resistance, Nutritional Quality and Productivity Traits in Groundnut (Arachis hypogaea L)

Subject Groundnut
 
Description 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....
