Genotypic correlations between ABA levels and growth rates in ears and silks in a recombinant inbred line (RIL) population (Cimmyt P1 X P2) in two trials (2001 and 2002) under severe water deficit at flowering at the Tlaltizapan, Mexico field station.

	Silk ABA 0 DAA in 2001	Silk ABA 7 DAA in 2001	Silk ABA 0 DAA in 2002	Ear ABA 0 DAA in 2002
Ear growth rate 0 to 7 day after anthesis	−0.90	−0.62	−0.82	−0.57
Silk growth rate 0 to 7 day after anthesis	−0.51	−0.56	−0.42	−0.87

Tissues were harvested at the indicated days after anthesis (DAA). (Source: Setter and Ribault, unpublished data).
