Description Genetic enhancement for resistance against the pod borer, Helicoverpa armigera
is crucial for enhancing production and productivity of chickpea. Here we provide
some novel insights into the genetic architecture of natural variation in H. armigera
resistance in chickpea, an important legume, which plays a major role in food and
nutritional security. An interspecific recombinant inbred line (RIL) population
developed from a cross between H. armigera susceptible accession ICC 4958 (Cicer
arietinum) and resistant accession PI 489777 (Cicer reticulatum) was evaluated for
H. armigera resistance component traits using detached leaf assay and under field
conditions. A high-throughput AxiomCicerSNP array was utilized to construct a
dense linkage map comprising of 3,873 loci and spanning a distance of 949.27 cM.
Comprehensive analyses of extensive genotyping and phenotyping data identified
nine main-effect QTLs and 955 epistatic QTLs explaining up to 42.49% and 38.05%
phenotypic variance, respectively, for H. armigera resistance component traits. The
main-effect QTLs identified in this RIL population were linked with previously
described genes, known to modulate resistance against lepidopteran insects in
crop plants. One QTL cluster harbouring main-effect QTLs for three H. armigera
resistance component traits and explaining up to 42.49% of the phenotypic variance,
was identified on CaLG03. This genomic region, after validation, may be useful to
improve H. armigera resistance component traits in elite chickpea cultivars.
