Differential nitrogen-use efficiency in wheat parents of doubled-haploid mapping populations

摘要

The modern wheat cultivars have been selected for non-limiting nitrogen (N) input situations and therefore require large amounts of fertiliser N. The relatively high price of fossil fuels increases the cost of N fertilisers, putting pressure on wheat farmers. Doubled-haploid mapping populations can lead to identification of specific loci that might be useful in marker-assisted breeding for increased N-use efficiency.
