Abstract EN
This study was carried out at Karahta Station of Field Crop Research, General Commission of Agricultural Scientific Researches during 2010-2011 and 2011-2012 cropping seasons in order to determine the phenotypic correlation coefficient between the traits and the path coefficients analysis for the most affected traits in grain yield.
In the first season, three hybrids, parental genotypes, first and second generation seeds were sown in two planting dates, one week interval.
The first and second back crosses were achieved.
The sowing was in rows, 3 m long, 25 cm between rows and 15 cm within row.
In the second season the sixth populations were sown for each of the three single hybrids.
Randomized completely block design was used with three replicates.
Three hybrids of durum wheat namely(Douma1*Sauady), (Bohuth9*Q88), (Hurrani*Q131) were evaluated to estimate path analysis coefficient, correlation between grain yield and components, for days to heading ,grain filling period, plant height, number of spikes per plant, number of grains per plant, Thousand kernel weight, grain yield per plant, protein content, and gluten content traits.
The mean average for all these traits revealed highly significant differences among crosses.
Grain yield showed a ppositive non-significant correlation with number of grains per plant, grain filling period, and thousand kernel weight.
while negative significant correlation with protein content.
The path coefficient analysis showed that the percentages of total contribution in grain yield were for grain filling period, number of grains per plant, protein content, and thousand kernel weight.
While That means of grain yield improvement can be achieved by increasing grain filing period, number of grains per plant, protein content and thousand kernel weight.
