Abstract
Spring wheat cultivars Ghaznavi-98, Khatakwal, ICP-3, Inqilab-91, ID-458, Fakhre Sarhad, Takbeer, Pirsabak-85, Tatara and Suleman-96, and their 30 F SUB 1 hybrids were evaluated in Peshawar, Pakistan, during the 2002/03 cropping season to estimate mid-parent heterosis for yield and yield-related traits. There were highly significant genetic differences among parents and F SUB 1 hybrids for productive tillers per plant, spike length, spikelets per spike, kernels per spike, 1000-kernel weight and grain yield per plant. The mid-parent heterosis estimates of F SUB 1 hybrids ranged from -24.5 to 107.9% for tillers per plant, -10.9 to 16.5% for spike length, -13.7 to 7.9% for spikelets per spike, -33.6 to 17.1% for kernels per spike, -21.7 to 61.6% for 1000-kernel weight and -55.7 to 156.8% for grain yield per plant. Ghaznavi-98 x Takbeer had the highest positive heterosis for the number of productive tillers per plant. Pirsabak-85 x Khatakwal showed the highest heterosis for spikelets per spike and kernels per spike. Khatakwal x Ghaznavi-98 and Tatara x Khatakwal exhibited the highest positive heterosis for 1000-kernel weight and grain yield per plant. Based on the mean performance and heterotic effects for the yield and related yield components, the parents of these 4 hybrids were suggested for use in wheat breeding programmes
