Abstract

Two research groups with complementary expertise will carry out physiological and genetical analyses of the behaviour of wheat in relation to C-allocation to root growth and nutrient-use efficiency. A doubled haploid population, partially mapped with molecular markers, is well differentiated for rooting traits. Studies with these lines will be done: (a) in the field in an infertile sandy soil given different N and P levels; (b) in columns of the same soil with a small compartment of labelled N and P located at depth; (c) in solution culture with controlled limitation of nutrient supply. Many traits associated with N and P acquisition and use will be scored and genes regulating their expression located to facilitate marker-assisted selection.
