Abstract
This research was conducted to separate variance of yield trait olive into its components and determine the heritability of this trait. To do that, 105 cultivars and genotypes cultivated at Tarom Research Station belonged to the Research and Education Center for Agriculture and Natural resources of Zanjan province, were evaluated for five years from 2010 to 2015. The base design of this experiment was a randomized complete block design with the effect of time on the model. Finally, the data were analyzed based on the split plot design in time. Then, based on the Expected value of each component, the genetic parameters related to the trait were obtained. For the five years of studies significant differences were observed between yield and tree, so that the highest yield (32.32 kg) was obtained from a single three. The value of the genetic component of the attribute was 40.81, which is a small amount indicating the high impact of the environment on this trait. The value of the inheritance of the trait was 53.44, which is significant due to the quantitative nature of the trait. Accordingly, based on the relatively high diversity index obtained from one of the suitable corrective methods for the yield trait in olive, could be "selection" among the elite genotypes.
