  Identifying functional traits


                                          SUMMARY


1) Better yielding genotypes have more open stomata, indicating they have
   deeper roots and access soil water

2) Genotypes that accumulate substantial stem starch reserves may be more
   able to sustain meristems and other respiring organs during a prolonged
   stress
    t

3) Genotypes that maintain partitioning to storage roots and have high harvest
   index yield better in drought

  • 24. Ginés-Mera Fellowship Workshop CIAT, Colombia, 12-13 May 2010 Identifying functional traits SUMMARY 1) Better yielding genotypes have more open stomata, indicating they have deeper roots and access soil water 2) Genotypes that accumulate substantial stem starch reserves may be more able to sustain meristems and other respiring organs during a prolonged stress t 3) Genotypes that maintain partitioning to storage roots and have high harvest index yield better in drought A.
