Pureline selection
Pureline is the progeny of a single, homozygous, self pollinated plant. With this method you select a large number of plants whose individual progenies are tested. The best progeny is then released as a variety. It is used to develop a variety from local selections, introductions and old pureline varieties. Pureline varieties are extremely uniform. Examples of pureline varieties are Mtu1, Patni6, T22 (India)
