The diploid and tetraploid wheats have a crossing barrier that inhibits development and viability of the F1 hybrid seeds which result from their pollination with rye. This barrier is ineffective in synthetic or natural hexaploid wheat × rye crosses. From the results obtained by crossing the Chinese Spring monosomic series to a diploid rye composite, it was concluded that the breakdown of this barrier in hexaploid wheats is determined by polygenes, but may also involve genedosage effects. While more than half of the hexaploidwheat chromosomes may contribute to the breakdown of the barrier, chromosome 1D had the strongest effect. Its absence resulted in shrivelled and inviable hybrid kernels similar to those obtained when the T. durum cultivar Langdon was crossed with rye.
