Abstract:
Heterosis or hybrid vigor is a natural phenomenon where by hybrid off spring of genetically diverse individuals show advanced physical and purposeful traits relatively to their parents and off spring. Heterosis has been increasingly implemented in crop developed for nearly a century, with the purpose of developing greater energetic, better yielding and better appeared cultivars. In this review present and examine three classes of crop heterosis usage: intraspecific heterosis, intersubspecific heterosis and wide-hybridization heterosis, with specific recognition on polyploidy species. Different pollination control systems used to reproduce for heterosis also are comparatively analyzed. Finally issues worried in heterosis studies and crop development are to be highlighted. In the present review the ultimate goal to provide insight into first class practices for amplifying heterosis ability.
