Comparing Two Statistical Models for Studying Genotype x Environment Interaction and Stability Analysis in Flax Ashraf A. Abd El Mohsen* and Mohamed M. Amein Department of Agronomy, Faculty of Agriculture, Cairo University Corresponding author: Ashraf A. Abd El Mohsen ABSTRACT: This study was conducted at the Agricultural Research Station, Cairo University at Giza Governorate, Egypt during 2011/2012 and 2012/2013 seasons to assess genotype x environment interaction and stability of straw and seed yields of seven flax cultivars, namely Sakha 1, Sakha 2, Sakha 3, Sakha 4, Giza 9, Giza 10 and S.46/4 under different nitrogen levels i.e. 20, 35 and 50 kg N/fad. The field experiments were laid out in a split-plot design with three replications in both years. The obtained results showed that fertilizer rate (50 kg N /fed) was the most suitable environment for straw yield. On the other hand the fertilizer rate (35 kg N/fed) was the most suitable environment for seed yield. Combined analysis of variance of straw and seed yields of seven cultivars tested at six environments showed highly significant (p
