Description The nutritional quality of peanut (Arachis hypogaea L.) products depends on the protein content, oil content, and composition of oil. Low genetic variability has been a major bottleneck in genetic enhancement of these nutritional traits in commercial cultivars. The present study was conducted to identify stable genotypes with
better nutritional traits and good agronomic performance
for use in future breeding programs. The 184 mini core accessions and four control cultivars were evaluated for nutritional traits for two seasons at two locations and for agronomic traits at one location. Significant genotypic
and genotype × environment interactions were observed for all the nutritional and agronomic traits in the entire mini core collection and within each A. hypogaea ubspecies of fastigiata Waldron and hypogaea. Eighteen accessions with higher nutritional traits such as protein content,
oil content, oleic acid, and oleic to linoleic acid
ratio with superior agronomic traits were identified
and their stability analysis resulted in identification
of a high oleic acid content (>73%) ccession (ICG 2381). On the basis of higher nutritional and agronomic traits 11 subsp. fastigiata and 10 subsp. hypogaea diverse accessions
were identified with more than two trait combinations
for use in peanut breeding programs for genetic nhancement of nutritional traits
