Either positive or negative traits could be selected for in nature, although selection for negative traits is extremely rare. A good example of positive selection at a rapid pace can be seen in antibiotic resistance in bacteria. Negative selection usually occurs in domesticated plants and animals. Let's say you have a very tasty strain of tomatoes. Instead of keeping some so you have seeds for next year you eat, sell or can all of them. This leaves you with no seeds, therefore you've selected out the positive traits of that particular plant.
I think this is what you are referring to.

artificial selection
What describes artificial selection?
Artificial selection refers to the process of intentionally breeding desirable traits in either plants or animals. It is also known as selective breeding.
What are humans select organisms for breeding based on traits?
Humans use selective breeding to pass desired traits to the next generation of plants or animals.
Selectively breeding plants and animals to accentuate certain characteristics demonstrates what concept?
artificial selection
What are the similarities and differences between Natural Selection and Selective Breeding?

What is conventional plant breeding?
it is the identification and selection of desireble plants of desired charecters
What concept is selectively breeding plants and animals to accentuate certain characteristics?
artificial selection
What is mass selection in plant breeding?
because mass selection is crossing plants with desirable traits , controlled breeding is mating organism to produce offspring with certain traits DESIRABLE TRAITS = CERTAIN TRAITS so mass selection is consider a form of controlled breeding

Why is it important to know the mode of reproduction of crops in plant breeding?
to determine its genetic composition, which, in turn, is the deciding factor to develop suitable breeding and selection methods.
