With the reference to pure line selection in self-pollinated crops, consider the following statements
1. Pure line selection is essentially based on the genotype of the plant.
2. It is effective only for heritable differences.
3. It is ineffective in creating new variations.
Which of the statements given above are correct?

With the reference to pure line selection in self-pollinated crops, the following statements are correct:
1. Pure line selection is essentially based on the genotype of the plant.
3. It is ineffective in creating new variations.
In pure line selection, large numbers of plants are selected from a self-pollinated crop and are harvested individually, individual plant progenies from them are evaluated separately and the best one is released as a pure line variety.
