Abstract

Evaluation of rapeseed and mustard adaptability is important in relation with the increasing demand for edible oil in Iran and lack of suitable cultivars for cold DRYLANDs. Randomized block designs can reduce experimental errors caused by spatial variability between blocks excluding intra-block variability. Control of spatial variability is an analysis that investigates the variance structure of each trial and uses an appropriate structure for estimation of effects in the trial. In this research, adaptation of 15 genotypes of spring type rapeseed and mustard were studied during three years in the cold DRYLANDs using spatial analysis. Results showed that, the randomized complete block design with first order auto-correlated errors along rows was the best model in the second year and the randomized complete block design with first order auto-correlated errors along rows and columns was the most effective model in accounting for spatial variability in the first and third year. There was not any evidence for fixed trend in this experiment. Based on the selected models, the best linear unbiased estimates for all genotypes were calculated. STABILITY analysis on estimated means showed that mustard genotypes Bard-1 and Sel-2 had the highest STABILITY in this experiment.
