WebMale Sterility In plant breeding, male sterility is an essential feature that stops self pollination in flora and promotes move-pollination. If the plant is a sterile male, there's no want for emasculation, that is generally accomplished in bisexual plant life to keep away from self-pollination all through plant breeding. consequently, the ...
