| Abstract | ||
| The study carried out to test genotype environment interaction for characters: root yield of sugar beet, root weight, total soluble solids, purity and sucrose percents, and estimates of broad sense heritability, simple linear correlation coefficient between characters and stability parameters for sugar beet varieties Juvena, Montiroza, Esperanza, Lietitia, Henrike, Progress, Valantina and Brigitta, which planted at six environments resulting from combination between three planting dates (15 July, 1 and 15 August, 2010) and two locations (Al-Hood belonging to Al-Qayara and center of Mosul) using randomized complete block design with three replications. It was shown from combining analysis of variance that mean square of both varieties and environments was significant for all characters except purity percent in the case of environments, and for the varieties x environments interaction was highly significant only for root weight and yield. Broad sense heritability was high for all characters and ranged from 63.41% for root weight and 97.8% for sucrose percent. It was shown positive highly significant correlation between root weight and root yield, and positive highly significant correlations between the characteristics, percents of total soluble solids, purity and sucrose with each. The results of stability parameters showed. The results of stability parameters showed that the varieties Montiroza and Brigitta were stable and fit for different environments for most characters, and some varieties were respond to a good environment for specific environments, while their was response to unfavorable environments shown by variety Valantina for purity percent. | ||
