Plants from D1–D3 segregated into presumed incompatibility classes and were assigned genotypes

  • The classification scheme assumes that SI is controlled by a single gene and that the parental plants had genotypes S1S2 and S3S4. The full-sib progeny therefore have genotypes S1S3, S1S4, S2S3, and S3S4. Only crosses between plants with no alleles in common are compatible.

  • a Indicates exceptional plants referred to in results.
