Description Peanut (Arachis hypogaea L.) is extensively grown
by resource-poor farmers in the semiarid tropics
where many abiotic and biotic stresses limit
the crop’s productivity and seed quality. Peanut
cultivars with enhanced host-plant resistance,
adaptation to abiotic stress, input-use efficiency,
and yield potential will maximize yield gains and
minimize inputs to sustain production. The peanut
mini core collection was evaluated for agronomic
traits in multienvironment trials at Patancheru,
India. The published information on 184 mini core
accessions revealed 28 accessions resistant to
abiotic stress, 30 resistant to biotic stress, and 18
that were agronomically desirable but susceptible
to stresses, while 16 were seed nutrient dense.
The mini core is part of the composite collection,
which was previously genotyped using SSRs. The
agronomic evaluation, stress response, and nutritional
information together with genotyping data
were used to identify genetically diverse germplasm
with agronomically beneficial traits: ICG
12625 (resistance to drought, low temperature,
late leaf spot [LLS], Aspergillus flavus Link, bacterial
wilt; high oil and good oil quality) and ICG
442 (resistance to drought, salinity, P deficiency);
ICG 12625 and ICG 2381 (resistance to rust, A.
flavus; good oil quality); ICG 12697 (resistance
to LLS, rust, A. flavus) and ICG 6022 (resistance
to early leaf spot [ELS], LLS); ICG 14710 (high oil,
Fe, Zn) and ICG 7963 (high protein, Fe, Zn); ICG
11426 (resistance to ELS, LLS, rust) and ICG 5221
(high Fe and Zn and good oil quality). Accessions
with adaptation to rainy and/or post-rainy environments
were ICG# 434, 5745, 8285, 10036, 11088,
11651, 12625, 15042, and 15419. These accessions
are ideal genetic resources that may be
used to develop agronomically superior and nutritionally
enhanced peanut cultivars with multiple
resistances to abiotic and biotic stresses.
