Groundnut is a major crop cultivated in the Sahel zone where water and high temperature stress are serious&#13;
constraints for its production. Investigating drought and heat effects on physiological traits, yield and its&#13;
attributes could significantly contribute for improving groundnut productivity and consequently the incomes&#13;
of farmers. A groundnut germplasm (268 genotypes) was evaluated in four trials during two years under&#13;
intermittent drought and fully irrigated conditions. Drought stress reduced pod yield up to 72 % compared&#13;
to 55 % at moderate temperature. The haulm yield decrease due to drought was 34 % at high temperature&#13;
and 42 % under moderate temperature. Haulm yield tended to increase under high temperature. Genotype&#13;
by environment interaction (GxE) was significant under well-watered (WW) and water stress (WS) treatments.&#13;
The genotype and genotype by environment (GGE) biplots analyses revealed several mega environments&#13;
under WW and WS treatments. The GGE biplots analyses revealed also several genotypes with high&#13;
performance and stability across year and temperature environments under both WW and WS conditions.&#13;
The regression analyses indicated that among several traits, only the partition rate was significantly&#13;
correlated to pod yield.</mods:abstract><mods:classification authority="lcc">Groundnut</mods:classification><mods:originInfo><mods:dateIssued encoding="iso8061">2013</mods:dateIssued></mods:originInfo><mods:originInfo><mods:publisher>Agronomie Africaine Association Ivoirienne des Sciences Agronomiques (</mods:publisher></mods:originInfo><mods:genre>Article</mods:genre></mods:mods>
