Description An investigation on genetic analysis of oil quality, yield and its components in
recombinant inbred lines of groundnut was undertaken during kharif 2011 and kharif 2012 at
Main Agricultural Research Station, University of Agricultural Sciences, Dharwad. The
experimental material comprised of 816 RILs derived from GPBD-4 x GM 4-3 along with
these two parents and five checks in 2011 kharif and 2012 kharif and 86 selected lines
evaluated in 2012 kharif. These Recombinant Inbred Lines (RILs) were grown in a replicated
yield trail by adopting RBD design and observations were recorded on eleven quantitative
characters, eight fatty acids, two foliar diseases. Significant genetic variation was observed in
Recombinant Inbred Lines (RILs) studied as evidenced by wider range and high PCV and
GCV for most of the characters studied.
High heritability with high genetic advance were recorded for 100- kernel weight, pod
yield, kernel yield, oil yield, oleic acid, linoleic acid, and O/L ratio. Character association
study revealed positive association of pod weight per plant, days to 50 per cent flowering,
days to maturity, oil content with pod yield. Oleic acid and linoleic acid were negatively and
significantly correlated, whereas O/L ratio had significant positive correlation with oleic acid
and significant negative correlation with linoleic acid.
The superior Recombinant Inbred lines identified for pod yield were RIL No. 723
(6549 kg/ha), 192 (6516 kg/ha), 600 (6371 kg/ha), 718 (6227 kg/ha), 750 (6005 kg/ha), for
high oleic acid 38 (73.4%), 812 (73.3%), 39 (71.2%), 34 (71%), 816 (68.6%) all these lines
are medium resistance (score 5-6).
