Abstract
Chromosome aberrations during early embryo and endosperm development were analysed in reciprocal crosses between Chinese Spring wheat monosomic for chromosome 4B (M4B) and a Chinese Spring substitution line in which chromosome 4B was replaced by the homoeologous 4S1 chromosome of Aegilops sharonensis [4S1(4B)]. In M4B x 4S1(4B) crosses, chromosome aberrations were common in both embryo and endosperm, while in 4S1(4B) x M4B crosses they were confined to the endosperm and occurred at a lower frequency. Chromosome aberrations also occurred in the endosperms of self-pollinated 4S1(4B) plants. The types of aberration were similar to those seen at first pollen grain mitosis in plants monosomic for chromosome 4S1, and which are thought to be the basis of its preferential transmission. It is therefore likely that a single mechanism is responsible for aberrations in meiocytes, embryos and endosperms. The implications of chromosome aberrations during early seed development for the agronomic applications of the 4S1 chromosome are discussed.
