Cytogenetics and biotechnology to accelerate wheat breeding in southern Brazil: production of synthetic hexaploids from related species and doubled haploids from anther culture



Cytogenetics and biotechnology to accelerate wheat breeding in southern Brazil: production of synthetic hexaploids from related species and doubled haploids from anther culture



Wheat for the nontraditional warm areas Proceedings of an international conference, July 29 August 3, 1990, Foz do Iguacu, Brazil: 530-536



Crosses were made between Triticum durum (2n = 28, AABB) and Aegilops squarrosa (2n = 14, DD) followed by chromosome counting and colchicine treatment of the embryo cultured hybrids (2n = 21, ABD). Eleven hexaploid synthetic homozygous lines (2n = 42, AABBDD) were produced and doubled haploid lines harvested after 20 months using anther culture.
