Exotic Germplasm / Challenges:Exotic Germplasm / Challenges:Exotic Germplasm / Challenges:Exotic Germplasm / Challenges:
Difficult to evaluatePhotoperiod Sensitivity unattractive phenotype
Tall plants with high ear placement
Standability Issues generally have weak rootsHigh Harvest Moisture generally later maturity
Tight husks and slow dry-down
Requires more ResourcesLarger Popn size and more segregates to evaluateLong Term Investment (success in 2nd to 3rd Gen.)
