How plants can breed?

Plant breeding is the purposeful manipulation of plant species in order to create desired genotypes and phenotypes for specific purposes.
This manipulation involves either controlled pollination, genetic engineering, or both, followed by artificial selection of progeny.
Plant breeding often, but not always, leads to plant domestication.For example, a mildew-resistant pea may be crossed with a high-yielding but susceptible pea, the goal of the cross being to introduce mildew resistance without losing the high-yield characteristics.
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).
The progeny from that cross would then be tested for yield and mildew resistance and high-yielding resistant plants would be further developed.
Plants may also be crossed with themselves to produce inbred varieties for breeding.
