Abstract
Eight genotypes of Triticum turgidum L. ssp. durum (2n = 4x = 28) were pollinated by three varieties of maize (Zea mays L.) to obtain green haploid durum wheat plants. After pollination, plants were cut and maintained in a nutrient solution until the ovary developed, and the embryo was rescued through in vitro culture. The influence of both the wheat and the maize genotypes on ovary development and embryo and green haploid plant formation was apparent. Ovary development and embryo formation were observed in all wheat genotypes with at least one maize variety. Green plants were obtained from six of the eight cultivars tested. Sixty doubled haploid green plants were recovered after colchicine treatment.Key words: Triticum turgidum ssp. durum, Zea mays, intergeneric hybridization, embryo rescue, haploid green plants.
