Abstract
Simple correlation between oil yield and its component characters was studied to identify
the selection indices in three crosses using F 2:3 population of ICGV 91114 x ICGV 01279, K 1375
x ICGV 98170 and ICGV 02125 x ICGV 98175 under drought stress and non stress conditions.
Oil yield per plant and kernel yield per plant expressed significant and positive correlation
with number of pods per plant, 100- pods weight, 100- kernels weight, shell weight, shelling
percentage and pod yield per plant under both drought stress and non stress conditions in
all three crosses. Hence, these traits might be considered as selection indices irrespective
of stress situation, and they might be considered as important yield attributing characters
and due emphasis should be placed while breeding for high kernel yield in groundnut
