Development of an environmentally friendly F1 hybrid breeding technology

Contract nr: QLK5-CT-1999-30902
Project type: RS (Research and Technological Development Project)
Starting date: 01-10-2000
Duration: 36 months
Total cost: 2,011,986 EUR
EC Contribution: 945,322 EUR
Scientific Officer: Richard HARDWICK
Research topic: 5.1.1. Sustainable agriculture/Animal Systems

Abstract:
F1 hybrid is a proven breeding tool since it gives both a better yield of crops and natural protection of breeders' rights. It relies on parental homozygosity and, in most crops, reversible male sterility. The former ensures the uniformity of the hybrid crops, the latter allows large-scale hybrid seed production without emasculation. Instead of repeated self-pollination, a rapid way to reach 100% homozygosity is through microspore embryogenesis followed by chromosome doubling to produce doubled haploid (DH) plants. Unfortunately, this is only feasible in a few crops and cannot combine with male sterile system. As a multidisciplinary consortium, HybTech will use in vivo metabolic starvation to establish a widely applicable breeding technology that can combine reversible male sterility and production of DH plants. It will provide a rapid way to generate new Fl varieties without releasing transgenic pollen into the environment.
