Study of Grain Yield and Some of its Components of Some Promising Strains of Durum Wheat (Triticum durum desf.) in the Conditions of Idlib Governorate

Abstract

 This experiment was carried out at Tal Sandal Research Station, north of Idlib city, during the 2017/2018 agricultural season, with the aim of evaluating the productivity performance of 8 promising strains of durum wheat obtained from the Crop 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 two local controls. Yield and some productive traits were studied. The results showed differences in the values of the studied indicators according to the promising strain, where it was noted that strains D.49065, D.55649 and D.55758 were significantly superior in grain yield with an average of (4530 kg/ha, 3714 kg/ha, 3203 kg/ha) on all the studied controls. The strain D.55147 excelled in the two characteristics of the number of spikes and the number of grains in the spike over all the studied controls with significant differences. Grain yield was associated with a non-significant negative relationship with the characteristic of the number of days to puberty (r = -0.223), and a non-significant positive relationship with the characteristic of the weight of a thousand grains (r = 0.333), and the characteristic of the weight of grains in a spike (r = 0.273).
