Heterosis in intervarietal crosses of maize and its reduction in advanced generations



Heterosis in intervarietal crosses of maize and its reduction in advanced generations



Anales Cientificos, Peru, 6: 3-4, 173-184



The F1S, F2s and F3s of a diallel cross of five varieties pertaining to the race Perla were compared with three commercial double hybrids at two localities. The F1S did not all display positive heterosis for yield.
