TestHub · Accepted Answer

The advantage of self-pollination lies in the genetic structure maintained within the crop. Self-pollination results in splitting the crop's gene-pool into independent homozygous lines. Due to this, the preservation of varietal identity becomes easy. One major advantage of self- over cross-pollination is the fact that self-pollination isolates the crop reproductively from its wild progenitor.
