The material from a 7 x 7 half diallel cross involving
relatively drought tolerant inbreds of maize was raised
under rainfed condition. Analysis of variance revealed
significant differences for gca and sca effects for ten
characters studied. Among the parents, Ib 1073, Ib1143
and Ib 1155 were found to have negative gca effect for
days to 50 per cent tasseling, day to 50 per cent silking
and anthesis-silking interval. On the other hand, for plant
height, ear height and grain yield per plot, they had
positive gca effects. The crosses viz., 18 1073 x Ib 1143
and Ib 1073 x Ibl155 were found to have negative sca
effects for days to 50 per cent tasseling, days to 50 per
cent silking and anthesis-silking interval. These crosses
also exhibited positive sca for plant height, ear height,
number of leaves per plant and grain yield per plot.
