Description Globally, late leaf spot (LLS), a foliar fungal disease is one of the most important biotic
constraint in groundnut production. Multi-Parent Advanced Generation Inter Cross (MAGIC)
groundnut population was developed in a convergent crossing scheme using eight founder parents
to develop a mapping population for multiple traits includes LLS. The experiments conducted in
light chamber using detached leaf assay, and disease field screening nurseries at two locations
(ICRISAT and ARS, Kasbe Digraj) showed significant variability for LLS resistance and component
of resistance traits. Total 10 MAGIC lines with longer incubation (>11.0 days) and two MAGIC lines
with longer latent period (>27 days) than the resistant parent, GPBD 4 were identified. The MAGIC
lines, ICGR 171413, and ICGR 171443 with a lesion diameter of
