Evaluation of stability and compatibility of yield in advanced lines of Iranian long eggplants

In order to evaluate the compatibility and stability of the Iran eggplant lines, an experiment was conducted in a randomized complete block design with 3 replications and for 2 years in five regions of the country including Karaj, Neishabour, Minab, Urmia and Varamin. In this project, 8 advanced eggplant lines of the country, including lines N12, N61, Y3, Y9, SH2, SH12, V44 and B29, Were located with three longpril controls, Long Varamin and Chahbaland Neishabour long well mass were evaluated in compatibility and stability tests. Combined data analysis showed that the effect of year, place and treatment was significant, as well as the interactions of year in place, place in variety, and year in place in variety at the level of 1% probability. The results showed that among the tested areas, Neishabour with the average yield of 60.56 tons per hectare had the highest yield. Among the studied lines, Y6 and SH2 lines had the highest yield with an average yield of 55.4 and 54.78 tons per hectare, respectively. According to the results of stability analysis by AMMI method, lines N12, N61, V44, SH12 and Y3 are recommended as lines with general stability and average suitable performance for all regions of the Iran.
