bisexual flower
Emasculation is the technique in plant breeding for crop improvement programmes. It involves the removal of anthers from bisexual flowers buds of the female parents before the anther dehisces by means of a pair of forceps in order to avoid self or cross-pollination. However, if a female parent produces unisexual flowers there is no requirement for emasculation.
