Abstract
Groundnut (Arachis hypogaea L.) production in rain fed regions of Africa is mostly affected by
intermittent drought of different duration and intensity. Improvement of groundnuts for drought
tolerance could increase production in drought prone areas. Therefore, this study aimed at (i)
determining the effect of Watering regimes on yield and agronomic traits of exotic Groundnut
genotypes and (ii) identifying drought tolerant genotypes as source material for breeding and
drought tolerant varieties. Thirty groundnut genotypes were evaluated for drought tolerance under
well watered and water stress conditions in the screen house at Sokoine University of Agriculture
(SUA), Tanzania. A split plot design with four replications was used whereby the watering regimes
were the main plots with varieties planted as subplots Data were recorded on plant height, number
of pod/plant and pod yield/plant. Results showed that drought significantly reduced pod yield,
number of pods/plant and plant height. Eleven genotypes namely; ICG 2106, ICR 48, ICGS 44, ICG
3053, ICG 11088, ICGV-SM 87003, ICG 12235, ICG 13723, ICGV 02271, ICGV 97182 and ICGV
91114 gave better pod yield and number of pods/plants in water stress conditions and are
recommended for use in breeding program as drought tolerant varieties and sources for breeding
materials.
