Haploids, barley, wheat, cytogenetics, transformation
Development of genetic and cytological knowledge for cereal crop improvement. Research involves the understanding and improving haploid production systems and the development and testing of isolated microspore (haploid) transformation systems. Haploids are plants with a gametic chromosome number and are of value in shortening the breeding time required to develop new improved cultivars and as targets in mutation, selection and transformation research. Haploid isolated microspores are targets for direct production of homozygous transgenics and the production of doubled haploids for breeding programs. The last research involved perfecting culture media for microspores and procedures for introducing DNA into cells.
Dr. Kasha is no longer taking graduate students or Post-docs as his lab is closed.
