Artificial selection of plants through selective breeding

ARTIFICIAL SELECTION

The unnatural selection of plants with favourable traits to produce more disease-resistant plants with better quality and higher yield.

Selective breeding can remedy world hunger. For example, plant breeders can identify and characterize genetic sources of resistance to stripe rust, a fungal disease that infects wheat plants. They can also develop high quality crops that can defend against pests, diseases and environmental stresses. When agricultural epidemics occur, crops are devastated and food shortages rise. Selective breeding combats the increasing issues of food security, urbanization, population growth and shortages of energy and water. 

Let's take a look at a banana



Bananas are sweet and easy to chew .They are easy to hold as their length and thickness are just right to fit into your hand. All you have to do is to pull the top lightly and the anti-slip skin peels away. But how can such a perfect fruit exist?

In fact, bananas are not naturally made this way. In the wild, bananas are small and oval with thick tough skin peppered with large and hard seeds. You would probably need a sharp tock to peel it and have to keep spitting out the seeds.







The Rise Of The Banana

However, not all bananas were the same. Some were thinner, some less seedy and some sweeter. Years ago, people collected seeds from sweeter, thinner bananas to breed better bananas suited for human consumption.
