knowledge of traits associated with drought tolerance would be useful for developing breeding materials fortarget environments. to study these traits, 119 spring durum wheat breeding lines (bls) from the international maize and wheat improvement center (cimmyt) were evaluated along with local checks (one modern cultivar and three landraces) in three experiments under terminal and non-terminal d...

Abstract Background European canker, caused by Neonectria ditissima , is a disease of worldwide importance in apple production, yet knowledge about it limited, highly regional and sometimes contradictory. This an obstacle to successful management. Key aspects for Northern Europe are reviewed, based on research results from Germany Norway international literature data. Main topics Trunk cankers ...

pyramiding genes related to grain quality and resistance through marker assisted selection (mas) is an important approach in rice breeding programs. marker-assisted selection can be used for monitoring the presence or absence of these genes in breeding populations and can be combined with conventional breeding approaches. this study is a part of cultivar development program in iran through inte...

Eucalyptus is the second most planted tree on earth. Despite this ranking, its mature breeding programs, clonal propagation and deployment and short rotation time make it a leading target for biotechnology improvement. The recently completed eucalyptus genome project provides an enormous opportunity for understanding and developing new traits for eucalyptus forestry. The main obstacle for wides...

ground beetles (carabidae) with more than 40,000 described species worldwide are one of the main generalist predator groups and have an important role in reducing pest population and enhancing biodiversity of agricultural and wild ecosystems. specimens from different agricultural and forest ecosystems in azadshahr region, golestan province, northern iran, using pitfall traps and light traps, be...

Geospatial analyses were used to investigate the spatial distribution of populations of Halyomorpha halys, an important invasive agricultural pest in mid-Atlantic peach orchards. This spatial analysis will improve efficiency by allowing growers and farm managers to predict insect arrangement and target management strategies. Data on the presence of H. halys were collected from five peach orchar...

Several new superior apricot × plum (Prunus armenica × P. domestica) inter specific hybrid rootstocks have been recently produced in Iran, but the propagation of these hybrids by conventional means has been shown to be very difficult. In vitro propagation could be a reliable method for mass clonal propagation of these new rootstocks. In this study, in vitro establishment, proliferation and root...

The seedless barberry, ‘Bidaneh,’ is one of the most important cultivated small fruits in Iran. This cultivar propagated only by suckers, and so, establishment large-scale orchards not...
