| abstract |
This invention relates to the production of hybrids of cereal crops, particularly small grained cereals such as wheat and barley. In addition, the invention concerns new genetically altered plants, for use with this method. The plant line used in the production of hybrids, has a chromosome bearing a dominant male fertility restorer gene and a colour marker gene which confers a characteristic colouration on the progeny seed. The male sterile parental plant line is maintained by physically separating the progeny seeds by colour sorting. |
