Abstract
In order to transfer new technology and research findings to the farmers, and to evaluate advanced and promising lines of durum wheat under on farm condition, six lines including the checks (Aria) and (Dena) as well as bread wheat (Morvareed) were evaluated in two regions of the province in 2010-11. The experiment was laid out in an R.C.B.D with three replications and nine treatments. Result of yield trial in both regions showed that there were significant differences among lines. Treatments 9 and 5 the highest yield in both regions. The combined analysis showed that the effect of location on yield was significant. The higher yield in (Haji Ghoshan) might be attributed to favorable environmental condition and to lesser head fusarium. The significant genotype x location interaction showed that genotypes responded differently to environments. Based on suitable agronomical traits and in order to avoid biotic and a biotic stresses, genetic variability is of great importance, so that if this condition occurs, farmers, crop will not fail. Therefore genotype Treatments 5 as well as Aria and Dena might be recommended for the target regions as a sustainable crop production system.
