بررسی ارزیابی ژنوتیپ های پیشرفته گندم در شرایط زارعین

Credibility and success of a new technology depends on its results in target environments. To evaluation of improved bread wheat lines, ten genotypes were tested in Dehdasht, Basht and lishter regions in 2005. They were planted in randomized complete block design (RCBD) with 4 replications, through 300 kernel per square meter density and 25 centimeter row spacing. During vegetative and reproductive stages, different characters were recorded. The most important traits were: days to heading, plant height, number of tillers per square meter, number of grain per spike, thousand kernel weight, test weight and grain yield.. Based on simple and combined analysis of variance on grain yield ,there was significant difference between lines and locations. Genotype no. 2, 7 and 9 which had 3138, 3168 and 3227 kg/ha grain yield respectively, were in the same class with check (kouhdasht). These genotype was earlier and than check, with optimum plant height and grain weight. In consideration of grain yield and different morpho- physiologic traits and stability parameters, line no. 2, 7 and 9 had preference in comparison with the others. Final recommendation depends on its results on other stations.
