Description This dataset includes the Aflatoxin resistance on field screening of mini core collection was performed during the rainy seasons of 2008–2013 at ICRISAT-Niamey, Sadore, Niger. The data on preliminary field screening screening during 2008, a total of 176 in 2009, 162 mini core germplasm accessions and two resistant (55–347 and J 11) and two susceptible checks (Fleur 11 and JL 24) for pre-harvest aflatoxin contamination were presented. The experiments were laid out in a Randomized Complete Block Design (RCBD) with three replications. The plot size during 2008 was 4.5 m2 (1.5 m × 3.0 m) of three rows, each measuring 3 m with a gap of 50 cm between rows and 10 cm between seeds. During 2009, the plot size was 8 m2 with four rows of 4 m length, with a similar arrangement of accessions. A total of 34 accessions were screened during 2010 and 2011. Of these, 25 promising accessions were selected from 2008 and 2009 field experiments with a mean aflatoxin content of 1 μg kg−1 were also included based on our earlier studies. The standard checks, 55–437 (resistant) and JL 24 (susceptible) were also included in a 3 × 3 Lattice design with a plot size of 6 m2 with three replications. In all the experimental plots year-wise, care was taken to ensure uniform depth of planting. Standard agronomic and cultural practices were followed during all the years of experimentation. Plot-wise harvesting of accessions was carried out at optimum maturity. Pod yield data was also presented. In vitro seed colonization by A. flavus was also presented in percent infection
