Selection Methods in Plant Breeding Based On Mode of Reproduction - Breeding of Asexually Propagated Crops

Breeding of Asexually Propagated Crops

Asexual reproduction covers all those modes of multiplication of plants where normal gamete formation and fertilization does not take place making these distinctly different from normal seed production crops. In the absence of sexual reproduction, the genetic composition of plant material being multiplied remains essentially the same as its source plant.

Clones of mother plants can be made with the exact genetic composition of the mother plant. Superior plants are selected and propagated vegetatively; the vegetative propagated offspring are used to develop stable varieties without any deterioration due to segregation of gene combinations. This unique characteristic of asexual reproduction helped to develop a number of cultivars of fruits and vegetables including grapes, apples, pears and peaches.

Famous quotes containing the words breeding of, breeding, propagated and/or crops:

    Civility, which is a disposition to accommodate and oblige others, is essentially the same in every country; but good breeding, as it is called, which is the manner of exerting that disposition, is different in almost every country, and merely local; and every man of sense imitates and conforms to that local good breeding of the place which he is at.
    Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)

    The test of a man’s or woman’s breeding is how they behave in a quarrel. Anybody can behave well when things are going smoothly.
    George Bernard Shaw (1856–1950)

    Superstitious notions propagated in infancy are hardly ever totally eradicated, not even in minds grown strong enough to despise the like credulous folly in others.
    Samuel Richardson (1689–1761)

    That’s funny. That plane’s dustin’ crops where they ain’t no crops.
    Ernest Lehman (b.1920)
