Keywords:

  • crop improvement for nitrogen use efficiency (NUE) - in irrigated lowland rice;
  • need, for superior nitrogen-efficient rice varieties - poor fertilizer NUE;
  • plant traits, closely associated - with NUE, identified;
  • fertilizer NUE - relatively low, in irrigated lowland rice;
  • agronomic nitrogen use efficiency (AE) - partial factor productivity of applied nitrogen (PFP);
  • molecular approaches - in improving NUE;
  • breeding for high NUE, not easy - NUE, complex trait with multiple components;
  • genotypic variation in NUE - consistent across seasons, and soil nitrogen levels
