Study of stability and some genetic parameters of seven genotypes of wheat (Triticum aestivum L.).

A field experiment was conducted in Agricultural Research Center in Latifia / Ministry of Science and Technology (20 km) south of Baghdad for the seasons of 2012/2013 and 2013/2014 using seven genotypes of wheat are: M8, M9,M10, M11, M12, Furat and Tamoz 3. Using split plot with randomized complete block design (RCBD),with three replicates. Results show that there is significant differences for the most studied traits for Furat genotype included plant height, spikes number /m2 and tillers number/m2 with of 82.60 cm, 200.33, and 217.66 for the first season, and of 96.26 cm, 179.66 and 194.66 for second season respectively. Genotype M9 was superior for yield 606.66 g /m2 for the first season, while, in the second season genotype Furat which gave of 618.33 g/m2. Genetic variation was greater than the environment variation for the most traits, indicating the greater role of genetic variation. The Heritability percentage was high for tillers number / plant and medium for the rest of the traits. The genotypic and phenotypic variation coefficient were the average values for the most traits while, the genetic yield was high for M8, M12 and Tmoz33The M11,M10 and M8 genotypes were highest hemostasis for two environment .
