Some unique alleles existed in only some varieties. The insertion of CTTT alleles in the Tre locus (Figure 1A) and the G allele in the S3 locus (Figure 1B) were rarely found injaponicavarieties.
In the CBG locus were distinguished two (CTT)n repeats of(CTT)8and (CTT)19, but only a rice of low palatability (Palkong)possessed the (CTT)8allele (Figure 1C).
Moreover, the DNA banding pattern from the STS primers for palatability on
Koshihikari was similar to those of previous studies (12, 13, 17)(Figure 1D; Table 4).
