Heterosis in the F, hybrids between 13 winter wheats and
four diverse testers of spring wheat was determined for
grain yield and nine other traits. Two crosses IWWSN-6-110
x HPW42 and IWWSN-6-134 x HS240 showed significant
economic heterosis over the standard variety HS277 and
over the better parent for grain yield, grains per spike
and harvest index, whereas, the cross IWWSN-6-110 x
VL616 showed high heterosis over standard check only.
The crosses exhibiting significant heterosis over the better
parent for grain yield and yield attributing traits were
IWWSN-6-110 x HS240, IWWN-6-110 x HD2380,
IWWSN-6-134 x HD2380, IWWSN-6·134 x HPW42,
BEIJING637 x HS240 and JCAM/EMU"S"IIDOVE 'S" SWM
