Aim. The aim of the work was to study realization productive potential bread winter wheat plants under drought (Triticum aestivum L.). Methods. Wheat cultivars Bogdana and Perlina Podyllja were grown optimal conditions until earing-flowering phase, after that experimental transferred regime for 8 days. Optimal water supply restored end vegetation. Leaf surface area, mass shoot grains measured d...

Experiment 1 consisted in the genetic selection of two divergent lines D+ and Don the basis of AMEn value measured at 3 weeks of age with birds being fed a wheat diet, using the wheat Rialto cultivar characterised by a high in-vitro viscosity value. Significant difference (3413 J/g DM; P< 0.0001) in AMEn between lines reached 29 % on 4 generation. From the experiment 2 consisting in the test of...

the aim of this experiment was the study of dry matter and nitrogen (n) accumulation, remobilization and harvest index in different wheat cultivars. five bread wheat cultivars (darya, kuhdasht, shiroudi, tajan and zagros) and two durum wheat cultivars (arya and dena) were studied under optimum growth conditions during 2008-2009 at research field of gorgan university of agricultural sciences and...

Because of continuing increases in atmospheric CO2, identifying cultivars of crops with larger yield increases at elevated CO2 may provide an avenue to increase crop yield potential in future climates. Free-air CO2 enrichment (FACE) systems have most often been used with multiple replications of each CO2 treatment in order to increase confidence in the effect of elevated CO2. For screening of c...

ABSTRACT The selective effect of quantitative host resistance on pathogen aggressiveness is poorly understood. Because two previous experiments with a small number of bread wheat cultivars and isolates of Mycosphaerella graminicola had indicated that more susceptible hosts selected for more aggressive isolates, we conducted a larger experiment to test that hypothesis. In each of 2 years, six cu...

The 0AL[0RS wheatÐrye chromosomal translocation originally found in {Amigo| wheat possesses resistance genes for stem rust\ powdery mildew and greenbug biotypes B and C\ but also has a negative e}ect on wheat processing quality[ Recently\ a second 0AL[0RS translocation carrying Gb5\ a gene conferring resistance to greenbug biotypes B\ C\ E\ G and I\ was identi_ed in the wheat germplasm line {GR...

The effects of elevated CO2 and O3, singly and in combination were investigated on various physiological, biochemical and yield parameters of two locally grown wheat (Triticum aestivum L.) cultivars (HUW-37 and K-9107) in open top chambers (OTCs). Elevated CO2 stimulated photosynthetic rate (Ps) and Fv/Fm ratio and reduced the stomatal conductance (gs). Reactive oxygen species, lipid peroxidati...

Zak ERA8 (ENHANCED RESPONSE to ABA8) (Reg. No. GP-966, PI 669443) is a unique line derived from soft white spring wheat (Triticum aestivum L.) cultivar Zak that has increased seed dormancy but after-ripens within 10 to 16 wk. The goal in developing this germplasm was to use increased seed dormancy to improve tolerance to preharvest sprouting, a problem that can cause severe economic losses. Thi...
