lotter plate method and aflatoxin contamination by indirect competitive ELISA. The seed infection in the test lines
ranged from 0 to 40% and aflatoxin contamination was between 0 to 6,668 μg kg -1 , respectively. Five of the 30 elite
aflatoxin-resistant lines (ICGV 01002, ICGV 01149, ICGV 02148, ICGV 02189, and ICGV 02191) showed 80% foliage damaged) at 105
DAS.
In the elite variety trial, Spanish types, ICGV 02410 was the best performer (4.7 t ha -1 pod yield; 63% shelling
outturn) during the 2005 rainy season. The highest yielding control in the trial was ICGV 98374 (4.2 ± 0.33 t ha -1 ).
ICGV 02410 performed equally well during the 2005 rainy season (3.4 ± 0.21 t ha -1 pod yield). In the elite variety
trial, Virginia types, ICGV 02434 (4.9 ± 0.46 t ha -1 pod yield) outperformed the best control ICGV 98373 (3.2 ±
0.45 t ha -1 pod yield).
In Spanish elite variety trial, nine lines significantly out yielded (3.0 - 2.0 ± 0.21 t pod yield ha -1 ) the highest yielding
control, ICGV 98374 (1.6 t ha -1 pod yield). In this trial, ICGV 04060 (3.0 t pod yield ha -1 , 64% shelling out-turn,
LLS score = 5.0, and rust score = 2.0) was the best line. In the Virginia elite variety trial, three entries ICGV 04087,
ICGV 04091, and ICGV 04094 out-yielded the best control ICGV 86699 (1.7 t ha -1 , 60%, 4.0 and 2.0). Five lines
(ICGV 02410 and ICGV 02411 in the Spanish group, ICGV 02429, ICGV 02434, and ICGV 02446 in the Virginia
group) were selected for inclusion in international trials.
High oil content: Forty-six breeding lines were evaluated during the 2005/2006 post-rainy season for oil content
and pod yield in a replicated trial. ICGV 01274 (5.5 t ha -1 pod yield, 49.0% oil content, and
1.9 t ha -1 oil yield) and ICGV 00009 (5.4 t ha -1 , 50.5%, 1.8 t ha -1 ), produced significantly higher pod yield than the
highest yielding control, ICGV 86564 (4.6 t ha -1 , 47.0%, 1.5 t ha -1 ). Both of these lines also had higher oil yield. But
for oil content per se, ICGV 00351 (4.3 t ha -1 , 51.0 %, 1.6 t ha -1 ) and ICGV 00171 (4.4 t ha -1 , 51.5%, 1.5 t ha -1 ) were
quite good. The oil content of entries in this trial ranged from 51.5 - 44.7%, and the protein content from 26.9% -
18.4%. Twelve lines had an oil content ≥50%. In the 2006 rainy season, ICGV 01274 (4.3 t ha -1 pod yield) was the
top performer under irrigated conditions.
Medium-duration: Seven hundred and ninety advanced breeding lines (including controls) in 16 replicated trials,
and 76 lines in 2 augmented trials were evaluated in the 2005/2006 post-rainy and 2006 rainy seasons for pod yield
and other agronomic traits.
