Abstract:

The proportion of loci deviating from the expected monogenic segregation ratios in the genera Lens. Capsicum, and Lycopersicon is significantly higher (61/114 genes, 54%) for progeny of interspecific hybrids than for progeny of intraspecific hybrids (7/52 genes, 13%). Although aberrant segregations are expected to be more common in progeny of interspecific hybrids, this is the first estimate of the magnitude of this phenomenon, based on a random sample of genes in a number of plant genera. We interpret these unequal segregations as the result of linkage between the markers and gene(s) that operate in pre- and postzygotic phases of reproduction. Such unequal segregations should be considered in planning breeding programs.

Unequal segregation of nuclear genes in plants

The proportion of loci deviating from the expected monogenic segregation ratios in the genera Lens. Capsicum, and Lycopersicon is significantly higher (61/114 genes, 54%) for progeny of interspecific hybrids than for progeny of intraspecific hybrids (7/52 genes, 13%). Although aberrant segregations are expected to be more common in progeny of interspecific hybrids, this is the first estimate of the magnitude of this phenomenon, based on a random sample of genes in a number of plant genera. We interpret these unequal segregations as the result of linkage between the markers and gene(s) that operate in pre- and postzygotic phases of reproduction. Such unequal segregations should be considered in planning breeding programs.
