It is useful to begin with an outline of what I will talk about today. First, I want to discuss what is heterosis, what is the meaning of this word, and what are we describing when we use this word? Second, what is the genetic basis of heterosis? Heterosis is a complex phenomenon. And it would be useful to better understand the genetic processes that might contribute to heterosis. Third, what are the implications of heterosis for agriculture? Heterosis is widely used in agricultural systems throughout the world. And it has some strong implications for both how seed is produced to go into fields, as well as the yield and the types of plants that are utilized.
