Estimation of compatibility of some olive cultivars and genotypes in Tarom climate ‎conditions using non-parametric methods ‎

Investigation of the interactions of genotype× environment and integration of the effects of adaptation parameters are major problems in the decisions of plant breeding researchers. The aim of this study was to evaluate the adaptation and provide a strategy for the integration of sustainability parameters using non-parametric methods. For this purpose, one hundred genotypes and olive cultivars collected from all over Iran, in Tarom climate, were planted in the form of a randomized complete block design with three replications in 2006 and studied during six crop years from 2011 to 2016. To study the interaction effects of genotype and environment, four methods of De Kroon/Van der Laan, Bredenkamp, Hildebrand and Kubinger were used and to determine the compatibility, nonparametric methods of Nassar & Huhn and Thennarasu were used. The effects of stability and yield criteria were carried using the "adjusted of Selection Index of Ideal Genotype" (ASIIG) and the resulting plot. Accordingly, Koroneiki and Conservalia cultivars were the best cultivars for stability and yield index and QG12, BN8 and BASH genotypes were ranked last in terms of stability and yield.
