Abstract

Background & Objective: This study was conducted to investigate the effect of moving averages, olive yield, elimination of Biennial bearing effect and data purification to study yield stability of some olive genotypes. Materials & Methods: For this purpose, 100 genotypes and cultivars during 6 years, from 1391 to 96, were planted at Tarom Research Station in Zanjan province. This experiment was performed based in a randomized complete block design (RCBD) with three replications. After collecting performance data based on kilogram / tree, in order to correct the data and eliminate the noise caused by the Biennial bearing effect of annoying, data analysis was performed based on the original and corrected data, respectively. Results: The results showed that the environmental component of the total variance for the corrected data decreased from 35. 74% to 19. 61%. Also, the heritability component increased from 15. 02 to 38. 51%. The paired t-test for the pair of corresponding years confirmed the significant difference between the mean and the corrected mean data. Using genotypic variation coefficient and mean yield, it was determined that at least three genotypes 'NO7', 'KHBA' and ' MANZANILLA' of state change are in stability. Also, with respect to eight other computational Stability Parameters, in most cases, genotypes were ranked with rank change Conclusion: Finally, it was determined that interfering with or eliminating the Biennial bearing effects can significantly affect the selection of stable genotypes. According the importance of eliminating the effects of Biennial bearing during the study period, it is necessary to apply the calculations on genetic material to the corrected data to determine the truth of the genetic potential of genotypes to show true and heritability compatibility.
