Description An investigation on genetic variability for oil content, oil quality and other
yield traits in advanced breeding lines of groundnut was undertaken during summer
2009-10 and kharif 2010 at Main Agricultural Research Station, University of
Agricultural Sciences, Dharwad. The experimental material comprised of 150
advanced breeding lines with 10 checks. The advanced breeding lines were grown in a
replicated yield trail by adopting RBD design and observations were recorded on
fourteen quantitative characters, different fatty acids, foliar disease and iron chlorosis
incidence.
Significant genetic variation was observed in advanced breeding lines 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 number of
primary branches, 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 advanced breeding lines identified for different economic traits
were ICGV07249, ICGV06038, ICGV 06142, ICGV 03106, ICGV 04061, ICGV
05100 for oil content (>54%), ICGV 05097 for kernel yield (>2950 kg/ha), ICGV
06142, ICGV 05097 for oil yield (>1465 kg/ha), ICGV 06229, ICGV 86564, ICGV
07368, ICGV 06188, ICGV 06199, ICGV 06124 for 100- kernel weight (>68 g),
ICGV 06110, ICGV 06175, ICGV 00446, ICGV 00440 for oleic acid (>63%),
ICGV 03043, ICGV 02410, ICGV 04061, ICGV 06142 for foliar disease resistance
and ICGV 99019, ICGV 99017, ICGV 07026, ICGV 06424 for tolerance to iron
chlorosis.
