“…Using selenium in water deficit stress condition increased mentioned traits as compared to treatment without using selenium. In between treatments of stress, the highest magnitude of measured traits was found from treatment of water deficit stress in stage V 8 . Least grain yield under water deficit was obtained from treatment of water deficit stress in grain filling stage and without Selenium application (Table 3).…”

“…Significant yield losses occur due to water stress in both temperate and tropical environments of other continents that also provide maize for local and global consumption [8] . In order to stabilize and increase global maize production for a burgeoning world population, the development of maize varieties with enhanced drought tolerance continues to be an important objective.…”

“…In many Asian countries (e.g., Iran) due to the calcareous nature of the soils, high pH, low Organic Matter (OM), salty soil, continuous drought, high bicarbonates in the irrigation water and an imbalanced application of fertilizers [4] , plants growth most of the time affected by different abiotic limitations. Across the globe today, maize (Zea mays L.) is a direct staple food for millions of individuals and, through indirect consumption as a feed crop, is an essential component of global food security [8] . Drought and its consequent stress are one of the important factors which restrict agriculture production in Iran and reduce the use efficiency of dry lands.…”

Problem statement:To investigate the effect of nutrient application on agronomical characteristic and water use efficiency under water deficit stress of hybrid maize 704, an experiment was arranged in a split plot factorial based on a complete randomized block design with four replicates in the research station of Islamic Azad University-Arak Branch, Iran in 2007. Approach: Main factors studied were four irrigation levels including irrigation equal to crop water requirement, water deficit stress at eight-leaf stage (V 8 ), stage of blister (R 2 ) and stage of filling grain in the main plot. Combined levels of selenium treatment (without and with application 20 g ha −1 ) were applied 2 weeks before execution of water stress treatment and micronutrients (without and with application) that was provided by specific fertilizer for maize called "Biomin", which contained Fe, Zn, Cu, Mn, B, Mo and Mg in the form of foliar application at six-leaf stage and 1 week before tasseling stage at the rate of 2 L ha −1 were situated in sub plots. Results: Results indicated that effect of water deficit stress on 1000 grain weight, grain yield, harvest index and water use efficiency at different growth stages was significant at 1% level. Water deficit stress decreased grain yield 33% in grain filling stage as compared with control. Using selenium increased mentioned traits but the increase was non significant. Effects of twofold interactions of water deficit stress and selenium showed that using selenium in water deficit stress condition increased measured traits as compared with treatment without selenium. A negative antagonistic interaction was found between selenium and micronutrients on some measured traits. In between treatments of water deficit stress, highest grain yield (8159.33 kg ha −1 ) was obtained from combined treatment of water deficit stress at eight-leaf stage with selenium application and without micronutrients which compared with treatment of irrigation equal to crop water requirement, without selenium and microelements did not differ significant. Conclusion: According to the results of experiment, using microelements in optimum water availability and using selenium in water deficit stress condition increased mentioned traits as compared to treatments control.

Maize is one of the most important food and feed crops in the world including Southeast Asia. In spite of numberous efforts with conventional breeding, the maize productions remain low and the loss of yields by drought and downy mildew are still severe in Asia. Genetic improvement of maize has been performed with molecular marker and genetic engineering. Because maize is one of the most widely studied crop for its own genome and has tremendous diversity and variant, maize is considered as a forefront crop in development and estimation of molecular markers for agricultural useful trait in genetics and breeding. Using QTL (Quantitative Trait Loci) and MAS (Marker Assisted Breeding), molecular breeders are able to accelerate the development of drought tolerance or downy mildew resistance maize genotype. The present paper overviews QTL/MAS approaches towards improvement of maize production against drought and downy mildew. We also discuss here the trends and importance of molecular marker and mapping population in maize breeding.

“…Maize had its origin in a semi-arid area, but it is not a reliable crop for growing under dry-land conditions, with limited or erratic rainfall (Campos et al, 2004). Monneveux et al (2006) reported that seasonal drought was the most important limiting factor for producing maize in the world.…”

This research was carried out in 2014 at the Research Farm of the University of Tabriz, Iran. The experiment was arranged as split plot on the basis of randomized complete block with three replicates to assess the effects of four irrigation intervals (irrigations after 60, 80, 100 and 120 mm evaporation) on physiological and agronomical traits of three cultivars of maize (Zea mays L.; 'SC704', 'NS640', 'DC303': late, mid and early maturing, respectively). Irrigation intervals and maize cultivars were assigned to the main and sub-plots, respectively. Leaf temperature of all maize cultivars significantly increased, but chlorophyll content index, maximum efficiency of photosystem II, number of grains per plant, 1000 grain mass, plant biomass, grain yield and harvest index significantly decreased with increasing irrigation intervals. Late maturing cultivar ('SC704') was superior in all studied traits, followed by mid ('NS640') and early ('DC303') maturing cultivars. It was concluded that water limitation can potentially reduce performance of maize cultivars in the field, but the extent of this reduction depends on genotype and severity of stress.Key words: chlorophyll content; leaf temperature; maize; photosystem II; drought stress IZVLEČEK USPEVANJE SORT KORUZE (Zea mays L.) V RAZMERAH SUŠNEGA STRESARaziskava je bila opravljena v sezoni 2014 na Research Farm of the University of Tabriz, Iran. Poskus je bil zasnovan kot poskus z deljenkami na osnovi popolnega naključnega bločnega poskusa s tremi ponovitvami za ovrednotenje učinkov štirih načinov namakanja (namakanje po 60, 80, 100 in 120 mm evaporacije) na osnovi fizioloških in agronomskih lastnosti treh sort koruze (Zea mays L.; 'SC704', 'NS640', 'DC303': zgodnje, srednje in pozno dozorevajoča sorta). Načini namakanja so bili vrednoteni na glavnih ploskvah, sorte koruze na podploskvah. Temperatura lista je pri vseh sortah značilno naraščala z večanjem intervala namakanja, lastnosti kot so indeks vsebnosti klorofila, maksimalna učinkovitost fotosistema II, število zrn na rastlino, masa 1000 zrn, biomasa rastlin, pridelek zrnja in žetveni indeks pa so se z večanjem intervala namakanja značilno zmanjšale. Pozno dozorevajoča sorta ('SC704') je bila v vseh preučevanih lastnostih najboljša, sledili sta ji srednje ('NS640') in zgodaj ('DC303') dozorevajoči sorti. Ugotovljeno je bilo, da pomanjkanje vode lahko potencialno zmanjša uspevanje koruze, a je obseg zmanjšanja odvisen od genotipa in jakosti stresa.
