Presence of insensitive alleles (Ppd-1a) in the photoperiod-sensitive cultivar Paragon and in near-isogenic lines.
| Genotype | Chromosome A | Chromosome B | Chromosome D |
|---|---|---|---|
| Paragon | |||
| P(GS-100-2A) | X | ||
| P(CS-2B) | X | ||
| P(S64-2D) | X | ||
| Triple Insensitive | X | X | X |
Paragon has Ppd-1b alleles in the three genomes. Insensitive alleles were introgressed in the A, B, and D genomes from GS-100, Chinese Spring (CS), and Sonora 64 (S64), respectively.
