Militating selection indices in some bread wheat crosses [electronic resource].

Includes references.

This study was carried out at EI-Giza Agric. Res. Station during four seasons from 2005/2006 to 2008/2009 to evaluate the effect of eight methods of selection indices on grain yield per plant, number of spikes per plant, number of kernels per spike and 100kernel weight of three bread wheat crosses. 1- Bulk method as a control, 2- Number of spikes per plant "S.I₁", 3- Number of kernels per spike S.I₂", 4- 100-kernel weight " S.I₃" , 5- Number of spikes per plant and number of kernels per spike withholding 100 kernel weight "S.I₁₂.₃'', 6-Number of spikes per plant and 100-kernel weight withholding number of kernels per spike "S.I₁₃.₂'' , 7- Number of kernels per spike and 100-kernelweight withholding number of spikes per plant "S.I₂₃.₁', 8- Number of spikes per plant, number of kernels per spike and 100-kernel weight ""S.I₁₂₃" After three cycles of selection in F2,F3 and F4, six genotypes from each selection indices were selected from each cross.I
