“…The high values of WTG recorded in T2 (46 g) compared to T4 (40 g per1000 grains), for both varieties, can be explained by the fact that the number of grains obtained in T4 is much higher compared to T2, thus suggesting competition between grains with respect to assimilates; this could also be explained by the fact that continuous irrigation has greatly stimulated the production of a higher number of grains per unit area, which resulted in negative feedback translated by a correlative reduction in the weight of all grains produced. These results are similar to those reported by Haddad et al (2016) who mentioned that the increase in the number of grains m À2 induces a decline of the WTG.…”

“…Ratings and measurements of growth traits and yield components were based on the determination of the duration of the vegetative phase counted in number of calendar days from 1 January to the date of removal of 50% of the barbs from the sheath of the standard leaf (Haddad et al, ). The following parameters were measured.…”

Plant growth and yield of cereal crops are seriously affected in drought‐prone environments, hence effective agricultural means are needed. This paper aims to evaluate the beneficial effects of supplemental irrigation, at different phenological phases, on theoretical yield components of two varieties (GTA‐Dur and Vitron) of durum wheat under field conditions. Field experiments included six water regime treatments: crop evapotranspiration ‘ETc’ throughout the wheat‐growing season (i.e. adequately irrigated); rainfed conditions (no irrigation); and four supplemental irrigation treatments (T1–T4) applied respectively at the beginning of four phenological phases of wheat growth (tillering, heading, flowering and grain filling). Yield components were significantly influenced at the beginning of the cropping season, while the components expressed in weights were influenced at late cropping. Theoretical grain yield of the variety Vitron increased by 33% at T1, 84.3% at T2, 424% at T3, 902% at T4 and 1100% at ETc. Water productivity (WP) increased by 45–70% in irrigation treatments compared to rainfed conditions. Our findings stress that the consistency between appropriate water regime and adequate varietal choice increases WP and crop productivity, and improves irrigation water conservation. Complementary irrigation substantially improves the valorization of water by crops in water‐limited areas such as hot arid and semi‐arid regions. © 2018 John Wiley & Sons, Ltd.

“…Grain yield is a result of the combined effects of genotype (G), environment (E), and their interaction (GEI). Differences among genotypes, in their response to environmental changes, are caused by GEI (Annicchiarico et al, 2005;Haddad et al, 2016). A crossover GEI type reduces heritability and selection efficiency (Ceccarelli et al, 1991).…”

The present study aimed to investigate the extent of variability and relationships between grain yield and morpho-physiological durum wheat traits. Sufficient variability was observed for most characters. Based on stress indices, either widely or specifically, adapted lines were identified. Path analysis pointed out to above ground biomass, harvest index, spike fertility and spike number as yield determinants, suggesting that these traits are of interest in the breeding program. The measured traits were classified within 6 principal components accounting for 79.45 % of the total variation. Breeding lines dispersed along first principal component exhibited substantial differences in performance and stress tolerance abilities. Cluster C3 lines were high yielding and stress tolerant. From this cluster, lines L24 and L14 were scored as the best for 7 and 5 traits out of 17 characters, respectively. Both lines are proposed for release and as parents in crosses to take advantage of their desirable characteristics. The results indicated that physiological traits were unrelated to each other and to morphological traits making difficult the concomitant selection for yield and stress tolerance driven by these traits. Complexes crosses, between parents carefully chosen for these specific characteristics, are necessary to enhance favorable genetic linkage and to generate new basic segregating populations with high genetic variability for these traits.

This research was conducted to screen and analyse the variability within twenty F 3 populations of bread wheat (Triticum aestivum L.) generated by Line x Tester mating design.The results indicated the presence of sufficient variability within and between F 3 populations for the eight measured variables, which represent plant phenology, physiology, yield and yield components. Different populations have been identified to improve the measured variables separately. The number of spikes appeared to be the most important determinant of grain yield.PCA and cluster analyses indicated that the Acsad 1069 /El Wifak and Acsad 1135 /Hidhab, with a relatively high grain yield, aboveground biomass and 1000 grains weight, are the best F 3 populations to improve the productivity. However, Acsad 899 /Rmada and Acsad 1135 /Rmada populations were earlier and had a low number of spikes. These populations had also favorable genes for heat tolerance.
