Kam-Morgan et al. The deviation was caused by an excess of homozygotes for TA1691 alleles. We now have analyzed marker segregation of 200 loci spanning the entire genome. In all cases, segregation distortion was caused by the deficiency of TA1704 homozygotes, except 7DS, where individuals for TA1691 homozygous alleles were deficient. We have created reciprocal backcross populations of almost 200 individuals based on male and female meiosis.
Similar analysis is underway for the alleles associated with other segregation distortion loci.
Plant and Animal Genome Abstracts V. to 1997 Publications list. Chromosome location of leaf rust resistance gene Lr43 from Aegilops tauschii in common wheat. T. Hussein, R.L. Bowden, B.S. Gill, and T.S. Cox. Wheat leaf rust resistance gene Lr43 was recently transferred from Aegilops tauschii Coss. Monosomic and telocentric analyses were used to determine the chromosomal and chromosome arm location of Lr43 .
