Determination of the transmission frequency of chromosome 4S l of Aegilops sharonensis in a range of wheat genetic backgrounds

Summary The transmission of chromosome 4S^l from Aegilops sharonensis was observed in a range of wheat genetic backgrounds. Chromosome 4S^l was transmitted at a very high frequency (at least 97.8%) in all crosses. The genetic background appears to only have a small effect on transmission. The frequency of transmission of chromosome 4S^l was the same in each genetic background through both the male and female gametes.
