| Abstract |
Four methods of breeding or selection representing different cycles phenotypic selection were evaluated in six spring bread wheat (Triticum aestivum L.) crosses.
The methods were :
1- The pedigree method (PM) with three cycles of breeding selection in F3, F4 and F5.
2- The modified bulk1 (MB1) two the cycles of breeding or selection in F4 and F5 were practiced.
3- The modified bulk2 (MB2) where only one cycle of breeding or selection in F3 was exercised.
4- The bulk method where only natural breeding or selection were involved (BM).
This study was conducted at the farm of El-Giza Agric. Res. station, ARC, Egypt, during four successive seasons from 2001/2002 to 2004/2005 to evaluate the efficiency of four different breeding or selection methods in improving grain yield potentiality and some other agronomic traits in six bread wheat crosses. The lines which were produced from various cycles were evaluated in terms of number of spikes/plant, number of kernels/spike, 100 kernel weight, kernel spike weight and grain yield/plant.
Results of single analysis of variance for every cross showed significant different for breeding or selection method in all crosses. Genotypes showed different significant for number of spikes/plant except crosses No. 4 and 5, number of kernels/spike and 100 kernel weight except crosses No. 1 and 5, kernel spike weight and grain yield/plant except cross No. 1. The interaction between genotypes and methods of breeding or selection was significant in all characters studied for all crosses except number of spikes/plant crosses No. 4 and 6, number of kernels/spike except cross No. 6 , 100 kernel weight except cross No. 1 kernel spike weight and grain yield/plant.
Combined analysis for all methods of breeding or selection, crosses and genotypes showed significant different for crosses (C), methods of breeding or selection (M), genotypes (G), (C x M), (M x G) and (C x M x G).
The best methods of breeding or selection for number of spikes/plant was (BM) followed by (PM). For number of kernels /spike (MB2), followed by (PM), for 100 kernel weight (MB1) followed by (MB2) for kernel spike weight (MB2), followed by (PM) for grain yield /plant (MB), followed by (MB2).
Results revealed that six bread wheat crosses differed in all studied characters. Cross No. 6 had highest number of spikes/plant, cross No. 3 had highest number of kernels/spike, 100 kernel weight and kernel spike weight, cross No. 5 the highest grain yield/plant
