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.]]>Gama, E.E.G., R.T. Vianna, V.N. Filho and R. Magnveca,1984136980Debnath, S.C.,1987Zea mays L.).]]>12161168Joshi, V.N., N.K.
