| Abstract | ||
| A field experiments were carried out in eight environmental sites in the province of Diwaniyah is (Almhnanwip, Aldga Rh, Shamiya,ALbedder , alslaheae , Shinafiyah, Alasdair and fagger) by sowing nine varieties of different origin wheat is (Tamouz 1, Tamouz 2, Maxibak, Sabah, Ibaa 95, latefeae, Ibaa 99, Abu Ghraib and Cham 6) during two agriculture seasons in 2013 and 2014 to study the proportion of the influence of the major components of variation in the recipe yield grains and interaction genetic and environmental stability phenotypic varition of statistical methods is a method of variation and coefficient of variation and collected genetic regression coefficient and deviation from the regression line and Ecovalence contrast firming and collection arranged standards in order to identify varieties that owns and yield high-rate stability. The results of the study the proportion of emotion of the components of variation that recipe grain yield influenced by genetic factor increased by( 61.53%,) while it was influenced by the adjective environmental factor increased by( 8.62%) the amount of overlap of genetic and environmental( 29.45% )of the total variance components showed overlapping genetic and environmental data results and there were significant differences between the varieties where he excelled and was variety ((Sabah)) across environments by giving a higher grain yield averaged 4156.8 kg / hector and significant differences between the environments where he excelled Almhnanw environment by giving a higher grain yield averaged 3682.8 kg / hector across varieties, According to a study phenotypic stability which interpreted the results, according to the concept of each standard where the agreed percentage variation coefficient of standards and standard deviation and the way Shuki and collection method that ranks Ibaa 95 variety is the most stable and consistent. While genetic taken agreed with the recipe grain yield variety Sabah is the most pointed way quotient while the coefficient of variation as soft Finlay and Wilknson to outweigh varieties Sabah and Tamouz 2 and Abu Ghraib as varieties have the stability of high and have high yield which is suitable for all environments. | ||
