On-farm evaluation of Aspergillus flavus and aflatoxin resistant varieties in Andhra Pradesh, India: On-farm
participatory varietal selection trials and the participatory evaluations of improved varieties have been carried out
with four (ICGV 91278, ICGV 91328, ICGV 94379, and ICGV 94434) varieties in Anantapur; and five (ICGV
91114, ICGV 91341, ICGV 93305, ICGV 94379, and ICGV 94434) varieties in Pileru area, in Andhra Pradesh,
India. The trials were planted in 18 farmers’ fields in six villages of the each of the two districts. Performance of the
4 selected groundnut improved varieties was better in all the 18 farmers’ fields in six villages in Anantapur district
and produced higher pod and haulm yield than the control TMV 2. Highest pod yield 1029 kg ha -1 was obtained with
ICGV 94434 in Cherlopalli village. The variety ICGV 94434 produced 40 - 43% higher pod yield in three villages,
and in the remaining 3 villages it produced 23 - 34% higher pod yield than the control TMV 2. From each plot,
about one kg pod sample was drawn (after recording the bulk pod yield). The damaged pod sub-samples and the
remaining pods were shelled and sorted in large and small kernel sub-samples. Large seeds, which are mostly used
for confectionery purpose, showed 0.4 - 32% A. flavus infection and 0 -897 μg kg -1 aflatoxin across the villages and
varieties. Overall, improved varieties showed reduction in A. flavus infection (31 - 50%) and aflatoxin
contamination (56 - 93%) over the controls. Aflatoxin levels in three varieties (ICGV 91328, ICGV 94379, and
ICGV 94434) was
