Abstract
This study was conducted at the Experimental Farm of the Sids Agricultural Research Station, Agricultural Research Center, Egypt, during 2007/2008, 2008/2009 and 2009/2010 seasons. The objective of this study was; to estimate the efficiency of pedigree, modified bulk and single seed descent methods in two bread wheat populations. The final evaluation of the F5 generation was done during 2009/2010 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. The pedigree method expressed significant desirable values for number of spikes per plant, 1000-kernel weight, number of kernels/spike and grain yield/plant than those bulk and SSD method. The pedigree method produced consistently more superior lines for grain yield/plant compared to the best parent and the two checks (Sids1 & Sids12)or the average. The best lines were number 16 (45.80g) , no. 14 (43.22g) number 15 (35.67g) , no. 5(35.55g) and no. 13 ( 34.96g) in pedigree method and no. 6(39.52g) in bulk method. For number of Spikes/plant the results indicated the pedigree method produced more superior lines followed by bulk and then by SSD over lines with 2, 12,14 and 16; 14 and Zero lines, respectively. Regarding to 1000-kernel/weight, 2,3,5,8,10,13,18 and 19; 5; and 2 lines showed, significant overlines for pedigree, bulk and SSD methods, respectively. For number of kernels/spike, one line showed significant high .The lines number 1, 16, and 17 in pedigree breeding method and the line number 1 and 10 in bulk method gave the highest number of kernels/spike. The mean squares for breeding methods in the second cross were significant for yield and its components. The pedigree method gave the highest values for grain yield/plant, number of spikes per plant and number of kernels per spike. While the bulk method gave the highest value for 1000-kernel weight. While, SSD method exhibited significantly higher for1000-Kernel weight and number of kernels per spike. The pedigree method produced consistently more superior lines compared to the best parent and two cheeks (Sids1 & Sids12)or the average population with no. 7, no.8 ,no. 12, no.13 and no.16; no.3, no.5, no.10 and no.15; no. 9 and no.20 for pedigree, bulk and SSD, respectively. The best lines were number 7 (38.30g), no.8 (48.23g) ,no. 12(40.50g),no.13(37.48g) and number 16 (40.71g) in pedigree method.
