Plant Breeding Research and Development: Glossary

Science Person Year—Work done by a person who has responsibility for designing, planning, administering (managing), and conducting: (1) plant breeding research, (2) germplasm enhancement, and (3) cultivar development in 1 year (i.e., 2,080 hours). Does not include technicians, farm and clerical workers, computer specialists, post docs, grad students, etc.

Plant Breeding Research—Research on the genetics of plants and methodologies of plant breeding and biotechnology usually done to provide fundamental information useful for making plant breeding more efficient and productive. Does not include basic research on plant molecular biology.

Germplasm Enhancement—Any activity that includes: (1) gene transfer via sexual and asexual means from germplasm accessions, and (2) increasing the frequencies of desirable genes in crop gene pools that will be used for developing parents or cultivars.

Cultivar Development—Any activity of crossing, transformation, and/or selection (including marker-assisted selection) among plants which has the direct purpose of releasing a crop variety.
