Determination of the Heterotic Groups of Maize Inbred Lines and the Inheritance of their 99 Resistance to the Maize Weevil

G. Asea · P. Gibson · M. Gafishi Kanyamasoro · J. Karungi

Maize weevil (Sitophilus zeamais Motschulsky) is a major maize (Zea mays L) storage insect pest in the tropics. Fifty-two inbred lines developed for weevil resistance were crossed to two testers, A and B, to determine their heterotic group…
