| Title : | APPLICATION OF AUGMENTED DESIGNS FOR FIELD EVALUATION OF BREAD WHEAT DOUBLED HAPLOID LINES: A PRELIMINARY REPORT |
| Abstract : | Doubled-haploid is an effective method to produce 100% homozygous lines in a single generation accelerating the release of new varieties and reducing the corresponding expenses. However, the existing problem in cases where the adequate quantity of seeds is limited is the inability to evaluate new germplasm in replicated experiments. In his attempt to confront this problem, Petersen proposed in 1985 the evaluation of new germplasm to be based on its division in blocks and selection to be performed regarding the yield of the randomly repeated control in each block. The aim of the present study was to use the aforementioned method to evaluate preliminary 37 doubled-haploid lines (DHL). The parental varieties of the DHLs,Greek cultivars “Acheloos” and “Vergina”, were used as controls. For the purpose of the study, 35 main spikes, one form each DHL and control, were used. The length of the spikes was measured, the number of spikelets was counted, and the 1000 kernel weight and total yield were recorded. The data analysis revealed that only one line exceeded the mean number of spikelets of the controls, one exceeded the mean yield of the controls and two exceeded the mean 1000 kernel weight of the controls (one was even better than the best control). The reported results indicate the presence of valuable genetic variability among the DHL after crossing cultivars “Acheloos” x “Vergina”. Further research is needed, after DHLs multiplication, using more plants and locations to draw more reliable conclusions. |
