Eight crosses of maize viz; F-103 x 17-105, F-105 x 17-103, F -113 x 17-107, 17- 107 x 17-113, 17-138 x 17-131,17131 x F-138, F-147 x F-132, F-132 x F-147 were made. These crosses (F1) alongwith their parents were planted to study the heterosis for plant height (cm), ear height (cm), ear length (cm), ear diameter (cm), number of rows ear-1 number of kernels row-1, 1000-kernels weight (g) and yield plant-1 (g) in F1 generation. It was concluded that a cross F-113 x F-107 showed maximum heterosis for yield and its components. Therefore this combination must be given due consideration to utilize for improving yield and its components in future breeding programme.
