Comparison of Some Genotypes of Durum Wheat for Growing and Production

Abstract

Eight wheat genotypes , seven mutations (7 , 26 , 38 , 49 , 53 , 63 , 82) and durum wheat (door 85) were grown in sandy loam soil at winter season 2009 / 2010 , in Al -Sufia District , a rural area in Ramadi city . Genotypes input with randomized block design in three replicates were used. The aim of the experiment is to understand how these genotypes are grown and produce in the west of Iraq . The number of tillers/ plant ,plant height, length of flag leaf, spike length, number of grains / spike, 1000 grains, date of maturity , lodging and grain yield were measured. Genotypes did not differ significantly in grain yield , number of grains / spike , number of tillers, plant height and spike length. Mutation (7) gave high rate of grain yield(4.62 t.h -1 ( and number of grains /spike (63.1). Whereas genotypes were significantly different in weight of 1000 grains and flag leaf length. Durum wheat (door 85) gave the highest rate of 1000 grains weight about 48.6 gm and flag leaf length 24.8 cm. Genotypes were different from each other in physiological maturity , door 85 cultivar and mutation 26 came early at 11 April, while mutation (82) late at 17 April , and length of maturity period was about 10 -13 days for each genotype.The genotypes were slightly or medium resistant of lodging. The genotype of durum wheat is growing naturally and gives economic yield.
