Genotype by environment interaction is one of the complicated issues in plant breeding programs for development of high-yielding with yield stability genotypes. To evaluate seed yield and yield stability of oilseed rape in four southern and northern warm regions of Iran (Zabol, Gorgan, Haji Abad and Sari), nine open pollinated spring oilseed rape lines together with seven cultivars were evaluat...

Extended Abstract Introduction and Objective: Investigation of the interaction of genotype × environment and identification of stable and high yielding cultivars in different environmental conditions is of great importance in plant breeding. The objectives of this study are to investigate the interaction of genotype × environment using GGE bilpot graphic method in advanced cross-breeding lines...

Due to the high importance of fenugreek in terms of nutritional and medicine, improvement of genotypes with high yield seems to be essential. Yield is a quantitative trait that is affected by the genotype-environment interaction. In order to evaluate stability and adaptation for seed yield in fenugreek ecotypes, the experiment was carried out during growing season for three consecutive years 20...
