SASHA Brief 2014: Heterosis Exploiting Breeding Schemes for Rapid Yield Enhancement

Eric Muthuri September 30, 2014 Comments Off on SASHA Brief 2014: Heterosis Exploiting Breeding Schemes for Rapid Yield Enhancement

Heterosis is a concept first explained by Gregor Mendel in 1865. Further, in recent studies heterosis for outbreeding crops ranks among the biggest impacts made by plant breeders to world food supply. During sweetpotato action for security and health in Africa (SASHA) Phase 1, clear evidence was generated for the …
