The response of maize hybrids of doubled haploid (DH) origin to different locations and soils was examined over two years. The performance of twenty-two hybrid combinations was compared to that of two standard hybrids with commercial value in order to investigate how hybrids of DH origin responded to changes in various environmental factors (soil status, water and rainfall supplies, heat stress). The results indicated that the individual genotypes exhibited diverse responses in different years and at different locations. In general, the majority of hybrids performed below the level of the standard mean, though it was possible to find a DH line that resulted in a hybrid capable of producing yields equivalent to that of the standards. The significance of these results is that the DH lines were developed via an in vitro plant regeneration system and were tested in multilocation performance trials after long years of selection. Up till now only DH lines developed in vivo have been introduced into cultivation.
