Self Fertilizing Crops (autogamous Crops)
Certain restrictions caused the mechanisms for self-fertilization (partial and full self-fertilization) to develop in a number of plant species. Some of the reasons why a self-fertilizing method of reproduction is so effective are the efficacy of reproduction, as well as decreasing genetic variation and thus the fixation of highly adapted genotypes.Almost no inbreeding depression occurs in self-fertilizing plants because the mode of reproduction allows natural selection to take place in wild populations of such plants.
Critical steps in the improvement of self-fertilizing crops are the choice of parents and the identification of the best plants in segregating generations. The breeder should also have definite goals with the choice of parents. Self-fertilizing are easier to maintain, but this could lead to misuse of seed.
Some of the agronomy important, self-fertilizing crops include wheat, rice, barley, dry beans, soy beans, peanuts, tomatoes, etc.

Famous quotes containing the words fertilizing and/or crops:
“One forgets words as one forgets names. One’s vocabulary needs constant fertilizing or it will die.”
—Evelyn Waugh (1903–1966)
“Paper is cheap, and authors need not now erase one book before they write another. Instead of cultivating the earth for wheat and potatoes, they cultivate literature, and fill a place in the Republic of Letters. Or they would fain write for fame merely, as others actually raise crops of grain to be distilled into brandy.”
—Henry David Thoreau (1817–1862)
