abstract: Multi-environment testing at five locations
for rust and late leaf spot (LLS) resistance with
41 introgressed lines (ILs) bred using marker-assisted
backcross breeding in the genetic background Spanish-
type groundnut varieties identified significant
genotype, and genotype 9 environment interactions
(GEI) for LLS disease resistance and yield parameters.
Significant GEI effects suggest the need to identify location specific breeding lines to achieve gains in pod
yield and LLS resistance. The observed variable LLS
disease reaction among the ILs in part suggests
influence of background genotype on the level of
resistance. A breeding scheme with early generation
selection using molecular markers followed by phenotyping
for LLS, and multi-location testing of fixed
breeding lines was optimized to enhance selection
intensity and accuracy in groundnut breeding. The ILs,
ICGVs 14431, 14436 and 14438 with pooled LLS
score at 90 DAS of 3.5–3.7 were superior to respective
recurrent parent for pod yield, with early maturing
similar to recurrent parents. The pod yield advantage in ILs is attributed by more number of pods, besides
resistance to LLS that contributes to better filling.
