The methods used by the plant breeder depend upon the reproductive structures and habits of the particular plants with which he is working. For example, the means by which a plant is naturally pollinated will determine how it must be handled at the time of flowering to secure self-pollinated seed or cross-poUinated seed. Methods of vegetative propagation may be used to multiply the plant after a desirable variety has been produced. In this way the plant grower avoids cross-poUination and the variations that appear when many cultivated crops are grown from seed. The best ways of propagating particular crops vegetatively may be found.
