There is no universality yet in strategies being used to enhance the efficiency of crop improvement schemes, especially the estimation of breeding
values of new variants. In Asia, for instance, induced mutations are used routinely and account for a lot of the officially released crop varieties. It is catching on in Africa, has been
used in Europe and the Americas for over 50 years. Also, the use of marker assisted selection (MAS) is becoming routine but more so in the private sector but the data are not very
easily accessible. It promises to be a technique of choice for a very long time to come though the marker types will continue to evolve. Currently, most researchers would use the polymerase
chain reaction (PCR)-based locus specific markers like simple sequence repeats (SSR) or the non-specific types especially the amplified fragment length polymorphism (AFLP). The prognosis
is that as capacity increases, there will be a shift to the use of more high throughput amenable assays such as single nucleotide polymorphisms (SNPs). Micropropagation, and other
in vitro culture techniques provide uniform planting material (clones) with identical attributes and disease-free. These techniques are paramount, if not mandatory for vegetatively
propagated crops and large scale farming.
