Researchers at the University of California, Davis have identified non-transgenic mutant plants capable of generating haploid offspring.
Generation of haploid plants greatly improves the efficiency and effectiveness of the breeding process, allowing the production of fertile true-breeding homozygous lines in a single generation. Identification and selection of diploid plants with a desirable combination of traits is accomplished by screening many generations of progeny and remains a time, labor, and capital intensive venture. Current technologies utilized for inducing haploidy, however, may have limited applicability, entail transgenic approaches, require special skills, or can be very time consuming. In light of global population growth and arable land constraints, an extraordinary need exists for the development of new technologies for the acceleration of plant breeding.
Researchers at the University of California, Davis have developed a technology that offers a non-transgenic method of haploid plant induction. The method can be easily and quickly implemented by breeders all over the world. It combines the speed of transgenic haploid induction with non-transgenic techniques and circumvents the stigma and regulatory hurdles associated with genetically modified haploid inducers.
This novel technology has multiple applications, including:
