Description Food and nutrition security still require new sources of tolerance to major abiotic stresses and high nutritional quality.
Groundnut, pearl millet and sorghum mini core collections are representing diversity of global collections but few studies
investigated the nutrients contents and the tolerance to low phosphorus (LP) and drought stress (WS). Under lysimetre
and pots conditions, subsets of these mini core collections were used to assess genotypic variation in nutrients contents
and identify new sources of tolerance to WS and LP. In a randomized completely block design with 5 replications,
water regimes and phosphorus treatments were imposed. Agromorphological and nutrients contents parameters were
investigated. ANOVA were performed to assess the genotype and treatments effects. WS decreased the transpiration
efficiency (47%), yield and its components (68%) in groundnut. Combined WS-LP reduced pods weight (83%). ICG3312,
ICG81, ICG13395 and ICG467 revealed tolerant to WS/LP. In Pearl millet, LP decreased 100 seeds weight (14%), panicle
and shoot biomass weight (25%), the booting date delayed except on IP1060, IP5869, IP9000, IP17532 and IP17775.
WS-LP decreased total biomass (35%) while LP reduced total N(4.5%), P(20%), K(23%), Fe(25%) and Zn(3%). IP17532, IP 5153 and IP 5581 revealed highest Fe content (524mgkg-1). In sorghum, LP delayed the booting date, decreased
biomass (32%) and WS-LP reduced biomass (74%). ISS2151, ISS705 and ISS862 revealed tolerant to WS-LP. LP
decreased total N(11%), P(32%), K(13%), Fe(13%) and Zn(11%). IS1412, IS311 and IS376 showed high Fe content
(515mgKg-1). Selected genotypes and traits might be useful in crops improvement for more adaptation and productivity.
