Comparison Among Three Breeding Methods In Bread Wheat

The objective of this study was to compare the effectiveness of pedigree (PM), modified bulk (MBM) and single seed descent (SSD) breeding methods for increasing grain yield in wheat. This study was conducted on the Experimental Farm of Sids Agricultural Research Station, Agricultural Research Center, Egypt, during 2007/08, 2008/09 and 2009/10 seasons. The final evaluation of the F generation was conducted during 2009/10 season. The selected lines were sown in the nested design with three replications. The efficiency of the breeding methods was evaluated on the basis of the following parameters: mean performance results in the first cross indicated that, the differences between breeding methods. In the first cross the (MBM) gave the highest values for grain yield/plant, while, (SSD) method exhibited significant grain weight and (PM) gave the highest value for number of spikes/plant and number of grains/spike. It could be concluded that (MBM) is considered the best breeding method for grain yield/plant and number of spikes/plant, comparing to (PM) and SSD in this cross. In the second cross the (PM) expressed significant desirable values for number of spikes/plant and grain yield/plant, while, the best lines were number 4 (80g) in the (PM), number 12 (90g) in (MBM) and number 12 (69g) in SSD method. The SSD method exhibited highly significantly heavy grain weight and high number of grains/spike. It could be concluded that (PM) is considered the better breeding method for number of spikes/plant and grain yield/plant than those (MBM) or SSD method in this cross
