Heterosis in winter x spring wheat crosses
Main Article Content
Abstract
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 12314-13M-OM-9M-3M-4WM-OWH x HD 2380.
