| Abstract | ||
| Field study was conducted at Malha irrigation project which partially reclaimed in marshland of Al madina district located during the growing season of 2012-2013 in clay loam soil evaluate wheat cultivars (Triticum aestivum L.) cultured under different levels of nitrogen fertilizers and determine selection index by path coefficient Experiment included (15) treatments result from interaction between three nitrogen levels (120-160-200 kgha-1) and five smooth wheat cultivars (Latifia, Tammoz2 , IPA-99 , Abu-Graib and IpA-95) split plot design in randomized completely block design were used in three replicates. Results showed a significant differences among cultivars in number of spike per M² number of grains per spike, weight of 1000 grain (gm) and grain yield (kgha-1) the cultivar Abu Graib gave (3948.98 kgha-1). No significant different between the cultivar in Biological yield. Results showed a significant differences between nitrogen levels, in the characters the level ( 160 kgha-1) gave high grain yield (3514.6 kgha-1) and gave hight number of grain per spike , the level (200 kgha-1) gave hight number of spike m-2 and Biological yield. The Interaction between the cultivar and Nitrogen level No significant different in the characters. | ||
