Abstract

Herbage production of temperature forages is more sensitive to annual variation in water supply than in any other climatic factor. Drought resistance is a compound phenomenon involving tolerance of dry soil, high evaporation, mineral deficiency, high temperature (with Howarth C.J., see RO 16103393, PU 66) and high irradiance. Its genetic control is therefore complex. The main aims are to identify the mechanisms underlying the most important traits contributing to (a) maintenance of production during moderate drought and (b) survival of and recovery from extreme drought. Current efforts in physiology and metabolism will be extended to the molecular level. Genetic diversity between and within species (especially in the Festuca-Lolium complex) will be exploited (a) as a tool to dissect traits and their genetic control and (b) as a source of germplasm for variety improvement.
