Abstract EN

The research was conducted at two sites, First in the Mashroo region / Babylon province, the second location in Alsuwera \ Wasit province during the autumn season of 2016 to compare the behavior of five varieties of potatoes (Bureen, Rivera, Arizona, Rudolph, Almodo), (RCBD) design with three replications .The results showed : At mashroo site , Bureen was superior to the rest of the varieties except Rudolph in plant height and number of leaves, and was superior to the rest of the varieties except Rivera in the leaf area and dry weight of the vegetative total, and gave the highest average of tubers number (7.20 tuber.Plant-1), total yield (506.77 g.plant-1) and marketable yield (24.33 tons.ha-1) was significantly surpassed on Elmundo, which gave the lowest average of these characteristics.

While in Alsuwera site, Bureen, Rivera, and Rudolph significantly surpassed Arizona and Elmundo in plant height.

Rivera was superior to Arizona and Elmundo in stems number and the dry weight of vegetative total.

Both Bureen and Rivera recorded the highest average of tubers number (6.27 tuber.Plant-1), significantly higher than Elmundo.

Rivera gave the highest average of tuber weight (110.56 g), total (692.99 g.plant-1) and marketable yield (33.26 tons.ha-1), thus superior to the rest of the varieties except Bureen.

While Arizona has the lowest rate for these characteristics.
