Genotype à Environment Interaction and Yield Stability Analysis of New Improved Bread Wheat Genotypes

Yield stability is an interesting feature of today’s wheat breeding programs, due to the high annual variation in mean yield, particularly in the arid and semi-arid areas. Eighteen bread wheat (Triticum aestivum L.) genotypes sourced from different regions were tested for yield stability and performance in four environments between 2007 and 2009 using various stability statistics. The experiment of each environment was laid out in a randomized...
