Abstract

This study was carried out with the aim of identifying eight inbreed line of maize through season 2016 in three different environmental location (Wasit, Diwaniyah and Nasiriyah) to determine the most stable inbreed. The study involved planting this breeds (Inp-6, Pio-17, Syn-9, Zm-17, Pio-3, S-10, MGW-1 and Ast-B). Using RCBD design to three replicate. The results showed significant differences between each of the inbreeds and location approved for the studied traits (ear length and number of rows in ear and the number of grains in the row and the grain yield of the plant). The result of the stability analysis, four of them (Inp-6, Pio-17, S-10, and Ast-B) showed high averages relative to the general average and the slope coefficients were to one within the two confidence intervals. It is the best in adapting to all environmental conditions. Inp-6 inbreed is superior to the ear length, which is 19.19cm in length, while the Ast-B is superior in both rows of ear and plant yield, with 23.35 rows and 322.83g respectively. While inbreedInp-6 and Pio-17 in the number of grains per row were 15.41 seed per row and some inbreed showed that It is adapted to the new environmental conditions as in the inbreed (Ast-B, S-10 of Australian origin and Pio-17 Yugoslav origin, which exceeded the individual grain yield of the localin breeds at 322.83, 312.87 and 284.57g / plant). The ast–B inbreed highest components and adapted to the conditions of the studied environments.
