STABILITY ANALYSIS AND TOLERANT TO WATER DEFICIT IN BARLEY AND WHEAT GENOTYPES

To evaluation of several wild wheat and barley genotypes in response to water deficit stress, experiments were laid out in randomized complete block design with three replicates in optimal and stress condition environment for three years. Data analysis showed a significant genetic diversity within genotypes in terms of grain yield, and the existence of significant genotype × environment interaction, made it possible to analyze data for genotypes stability to environment in this study. The stability analysis showed that Garni (an emmer variety) was recognized as the most stable genotype to water deficit stress with a high grain yield. The stress tolerance tests also found that the Garni genotype is more tolerant to water deficit stress than other genotypes. Based on the results obtained, Garni genotype was recognized as a stable genotype and the most tolerant genotype to water deficit stress that has a high grain yield, and it can be used as a crossbreeding parent in wheat breeding.
