Abstract
Maize [Zea mays L.] is one of the third most important
cereals next to wheat and rice in the world with respect to area and
production. Maize is also considered to be a valuable cereal forage
crop. It is one of the most important dual-purpose crops grown in
kharif, rabi and summer for grain as well as fodder purpose.
The present investigation consisted of 14 parents (4 lines +
10 testers), and 40 F1s were developed in a line x tester fashion. The
experiment was laid out in a randomize block design with three
replications at Main Forage Research Station, A.A.U., Anand during
kharif season of 2011. The objectives of this study were to
investigate the per se performance, magnitude of heterosis,
combining ability and type of gene action for 15 different traits.
Significant difference among parents and hybrids were observed for
various traits under study.
