Study of the Productive Efficiency of Some Genotypes of Durum Wheat (Triticum durum desf.) in the First Stability Zone

Abstract

 This experiment was carried out at Tel Sandal Research Station, 20 km to the north of Idlib city, during the 2017/2018 agricultural season, with the aim of evaluating the productivity performance of 7 promising strains of durum wheat obtained from the Crops Research Department of the General Commission for Scientific Agricultural Research in Damascus. Randomized complete block design was used with three replications for each strain in addition to 2 local controls. Grain yield and some morphological characteristics were studied. The results of the statistical analysis showed differences. The values of the studied indicators according to the promising strain, where it was noticed that the strains D.51822 and ACSAD 1453, D.55157, ACSAD 1431, and D.55670 were significantly superior in grain yield with an average of (3561,3549,3324,3314,3162 kg / ha) of all studied parameters, while the strain D.55157 was distinguished by its superiority in the characteristic of grain yield, early sepals, spike length and spike holder length over most of the studied parameters with significant differences. The strain D.55607 was distinguished in the characteristic of plant height and The length of the spike on most of the studied controls and with significant differences compared to most of the studied breeds. The results of the study of correlations showed that the characteristic of flag leaf area was associated with a strong positive significant relationship with the characteristic of plant height (r= 0.551**).
