Statement I is false because a pureline variety is not obtained from many heterozygous plants of cross-pollinated crops. A pureline is derived from a single homozygous individual through self-pollination over successive generations to maintain genetic uniformity. Statement II is true. While purelines aim to maintain genetic uniformity through strict self-pollination, over time, genetic variability may still occur due to factors such as mechanical mixture, natural hybridization, and mutation. These processes can introduce genetic variations in a pureline despite efforts to maintain purity through self-pollination.
