Reproductive development comprises of a number of stages, all of which can be affected by drought and eventually have an influence on seed filling, seed size and seed yield.

Genotypes better able to maintain seed size and yield must either avoid terminal drought by completing seed filling prior to the commencement of drought (Turner et al., 2001) or tolerate terminal drought and maintain seed filling during drought (Turner et al., 2001).
