Evaluation of spring bread wheat lines/ varieties in international observation nurseries and yield trials in moderat region of Iran
Journal Title: Scientia Agriculturae - Year 2013, Vol 1, Issue 1
Abstract
The main objective of this research was to evaluate spring bread wheat cultivars genotypes selected from joint project of Iran/CIMMIT using several indices. In order to selecting new spring bread wheat cultivars with high yield comparing to widely grown varieties, evaluating resistance to diseases, lodging, shuttering was conductted. Valuablility determination of plant genetic resources received from International centers for utilization in crossing blocks and as active introduction carried out with four set of international nurseies in selected sites via seperated experiments as replicated yield trial or screening nurseries according to test. In first experiment 50 entries was studied by using of an alpha latice model and two replications and 6 desirable genptype selected for further research. In second experiment 30 entries was studied by using of a randomized compelete block design with three replications and 6 superior lines were chosen for more evaluating. In third and fourth sets 287 and 86 entries evaluated as observation nurseries and finally 15 and 11 entries selectd for more studies respectively. For more evaluating, selected genotypes forwarded to preliminary regional wheat yield trial.
