Abstract

The paper briefly reviews the objectives and methods of the breeding programme, and considers the reasons for and inplications of the decision to breed for varieties to be grown from seed. Hybrid vigour and incompatibility are discussed, and methods of preparing parents for subsequent hybridisation are considered, mention being made of efforts to obtain haploids or di-monoploids. Inter-specific hybridisation and polyploidy are mentioned.
