Abstract A field experiment was carried out in Erzurum (Turkey) on winter wheat to analyse the effect of water stress at different growth stages – fully irrigated (FI), rainfed (R), early (EWS), late (LWS) and continuous (CWS), some quality characteristics 1995–96 1996–97 cropping seasons. Water had a substantial most characteristics. As averages seasons, CWS, EWS, R LWS treatments decreased grain yields by 65.5, 40.6, 30.5 24.0 %, respectively, compared with FI treatment. CWS increased...

Abstract Growth and yield of wheat are affected by environmental conditions can be regulated sowing time seeding rate. In this study, three times [winter (first week September), freezing (last October) spring April)] at seven rates (325, 375, 425, 475, 525, 575 625 seeds m −2 ) were investigated during the 2002–03 2003–04 seasons, in Erzurum (Turkey) dryland conditions, using Kirik facultative wheat. A split‐plot design was used, with as main plots randomized subplots. There a significant...

This study investigated the genetic diversity and population structure of 63 genotypes from Turkish bread wheat germplasm using iPBS-retrotransposons primers. The thirty-four iPBS primers produced a total 1231 polymorphic bands, ranging 8 (iPBS-2375) to 60 (iPBS-2381) alleles per marker, with an average number 36.00 alleles. polymorphism information content (PIC) marker varied between 0.048 (iPBS 2087) 0.303 2382), 0.175. numbers effective (ne), Nei (h), Shannon’s index (I) value were...

The growth and yield response of spring wheat to inoculation with foreign local rhizobacteria Erzurum (Turkey) origin was studied. At the first stage research, a greenhouse experiment carried out cv. Kirik using 75 bacterial strains isolated from soil 6 bacteria, control. According results 9 were identified. second stage, 20 treatments (9 strains, 4 levels N, control) investigated in field conditions. Seventeen had significant positive effects on tiller number per plant, 47 plant height, one...

Wheat genotypes should be improved through available germplasm genetic diversity to ensure food security. This study investigated the molecular and population structure of a set Türkiye bread wheat using 120 microsatellite markers. Based on results, 651 polymorphic alleles were evaluated determine structure. The number ranged from 2 19, with an average 5.44 per locus. Polymorphic information content (PIC) 0.031 0.915 mean 0.43. In addition, gene index 0.03 0.92 0.46. expected heterozygosity...

A strong statistical method for investigating the correlations between traits, assessing genotypes based on numerous and finding individuals who excel in particular traits is genotype–trait (GT) biplot analysis. The current study was applied to evaluate 11 sweet corn (Zea mays L. saccharata) correlate them analysis two cropping seasons Erzurum, Türkiye using RCBD experimental design with three reputations. results showed that were significantly different majority of examined variables...

In order to develop genotypes with stable, higher yields in dry farming conditions, it is necessary characterize genetic resources based on drought adaptation, determine suitable genotypes, and then use them breeding programs. This study was carried out at the laboratories of Field Crops Department Atatürk University Agricultural Faculty. A total 64 certified local bread wheat were used test germination characters under osmotic stress, cell membrane damage, paraquat tolerance. There...

Deficit plant nutrients, especially nitrogen, and weed competition are the most critical problems in organic farming. This research was carried out on plots of Agricultural Research Extension Center Atatürk University Faculty during cropping seasons 2006-07, 2007-08, 2008-09 under dry farming conditions. A factorial experimental design with 4 replications used to set up plots. The factors were 2 wheat cultivars (Kırik Doğu-88), 3 control practices (weedy control, hand weeding, dense sowing),...

A number of physiological traits have been proposed as selection criteria for late drought resistance and grain yield improvement in wheat. To characterize them terms resistance, 64 bread wheat genotypes were evaluated canopy temperature difference (CTD), leaf senescence rate (LSR), SPAD chlorophyll value, initial fluorescence (Fo), maximum (Fm), variable (Fv), quantum efficiency PSII (Fv/Fm), ash content, content two field experiments conducted irrigated conditions during the 2011-12...

Bu araştırma, Erzurum ekolojik koşullarına uygun ve yüksek verimli çeşitlerin belirlenmesi amacıyla 2009-10 2010-11 ürün yıllarında 64 ekmeklik buğday genotipi ile tesadüf blokları deneme planına göre yürütülmüştür. Tane verimi verim unsurları yönünden genotipler arasındaki farkların önemli olduğu belirlenmiştir.
