Abstract

BARLEY is one of the most important crops growing under various climatic conditions. For breeding purposes, cultivated areas of Iran have been categorized into three environmental regions of which BARLEY breeding program in cold zone is being conducted in eight agricultural research stations namely Arak, Ardebil, Hamedan, Jolgeh Rokh, Karaj, Miandoab and Mashhad. Since performance of a given genotype might vary from one location/year to another one, studying genotype ´ environmentinteraction (G´E) becomes important. Moreover, eligibility of cultivar release depends on our knowledge obtained by investigating G´E effect on stability of promising breeding lines. In the present study, in order to study stability and adaptability of 19 genotypes (with national check) an experiment was carried out in the above mentioned stations during two consecutive cropping seasons. The experimental trials were based on a randomized complete block design with three replicates. Various stability analyses was undertaken to study G´E interaction: 1- Regression based analysis e.g. Eberhart and Russell or Finlay and Wilkinson methods; 2- Variance based analyses e.g. Plaisted or Wrickemethods; and non-parametric analyses e.g. mean or coefficient of variation of Rank method. Different analyses applied led us to various results in which to some extend dissimilarities were shown. However, the analyses in many cases were able to confirm each other in presenting the most and the least stable genotype over the environments studied. Overall, the promising line no. 17 (MAKOUEE//ZARJOW/80-5151) was recognized as the best genotype examined in terms of being a high yielding and stable genotype, therefore these genotype was recommended for on-farm trials an release.
