Abstract

101 words

The study objective of this study is to characterise new potato clones for drought tolerance under Ugandan conditions. Study genotypes were subjected to three water stress levels and also crossed with susceptible, locally adopted varieties to estimate the combining ability of the tolerant genotypes. Results for yield and for indicators of drought tolerance showed greater tolerance to drought in the new clones than in the local varieties. Four of the promising clones were crossed with three of the varieties susceptible to drought to determine their combining ability for yield and drought related traits, and to generate segregating materials for further evaluation.
