RFLP technology, crop improvement, and international agriculture
Genetic markers, known as restriction fragment length polymorphisms (RFLPs), are likely to have a major impact on crop improvement. Major genes for disease and pest resistance, as well as ensembles of genes controlling complex traits such as yield and quality, can be tagged with tightly linked RFLPs. Once economically important genes are tagged, individual that carry these genes can be selected for based on the RFLP genotype. This may be essential when the desired plant phenotype is difficult or impossible to score. Undesirable chromosomal segments from one of the parents can also be selected against. To date, most RFLP research has been carried out in developed countries, but RFLPs are likely to have a major impact in the developing nations as well. Most developing countries already have s scientific foundation on which to build RFLP technology, but the use of RFLPs will require greater efforts to train scientists in RFLP techniques, improved strategies for transferring RFLP technology and equipment, adoption of techniques that do not require the use of radioactive isotopes, and an increased effort to integrate RFLPs into ongoing breeding programmes
