Drought tolerance forms a major challenge for plant breeding and gains now more interest in Europe, because drought periods are expected to increase in the 21st century as a result of climate change. During August 2003, August 2009, spring 2010 and spring 2011, four different drought periods in Belgium caused severe re¬ductions in dry matter production of the corresponding cuts in our fodder grass field plot trials. Dry matter production was clearly inhibited for perennial ryegrass genotypes, while tall fescue performed relatively better during the drought periods. Nevertheless, a high yield variation among perennial ryegrass families was found during and after the drought periods. In addition, the dry matter yield of different perennial ryegrass families after a drought period was positively correlated between three drought periods. Both the considerable variation and important correlations in response to drought within these genotypes show potential to improve drought tolerance in perennial ryegrass.
