Phenotype Select™

Selection throughout the conversion process.

Trait screening, experienced multi-character selection and controlled greenhouse advancement at every backcross generation.

More than trait recovery.

Phenotype Select™ combines trait screening with experienced, multi-character selection at every backcross generation. Rather than advancing plants based on trait presence alone, PSR evaluates large populations and selects individuals that most closely express the characteristics of the recurrent parent.

Approximately 1,000–2,000 plants can be screened at each stage, providing a broad population from which to identify trait-positive plants with the desired phenotype. In PSR programs, selected BC2 plants have demonstrated 95% or greater similarity to the recurrent parent based on evaluated phenotypic characteristics.

Verification before advancement.

Traits are screened at the seedling stage on greenhouse benches using the appropriate trait assay or herbicide screen. Selected plants are then advanced through the agreed backcross generations.

For programs carried through selfing, such as BC4S2, PSR can also perform trait homozygosity testing as a final step to identify ears that are homozygous for the target trait.

Efficient greenhouse-bench screening in flats makes it practical to evaluate substantial populations while conserving winter-location space and reducing exposure to the environmental uncertainty of an outdoor nursery.

Begin development while approvals advance.

Subject to applicable regulatory requirements and material agreements, conversion work may begin with PSR while trait approval is progressing in the intended market. This allows companies to advance their converted material sooner and be better prepared for testing and commercialization following approval.

PSR works with established trait providers to coordinate donor access and follows the applicable material transfer agreements and stewardship requirements throughout the program.
