By BCE grafting was well established and practiced. Another technique is the deliberate interbreeding crossing of closely or distantly related individuals to produce new crop varieties or lines with desirable properties. Progeny from the cross would then be crossed with the high-yielding parent to ensure that the progeny were most like the high-yielding parent, backcrossing. An example of this can be seen in Asia, where food production per capita has increased twofold. Gregor Mendel —84 is considered the "father of genetics ".
This improvement indicates plant breeding is an essential tool in gearing future agriculture to perform at a more advanced level.

Plant breeders have focused on identifying crops which will ensure crops perform under these conditions; a way to achieve this is finding strains of the crop that is resistance to drought conditions with low nitrogen. The question of whether breeding can have a negative effect on nutritional value is central in this respect. Application of biotechnology or molecular biology is also known as molecular breeding.
