The research was done in Erzurum, in 1996 and 1997. Three barley genotypes (Tokak 157/37, Cytris, and 1515) were used with five doses of N (0, 20, 40, 60 and 80 kg ha−1). Significant differences were observed

A field study with artificial inoculation was conducted using 38 winter wheat cultivars during the 2002-2003 at Erzurum, Turkey. Significant differences were detected among cultivars for reaction and yield components to the M. nivale. The most resistant winter wheat cultivars were Harmankaya and Pehlivan, and the most susceptible ones were Aytin-97, Kırgız-95 and Bayraktar. Yield components ...

This study was carried out at the laboratories of the Field Crops Department of Atatürk University Agricultural Faculty. A total of 64 certified and local bread wheat genotypes were used to test germination characters under osmotic stress, cell membrane damage, and paraquat tolerance. There were significant differences among genotypes with respect to the selection parameters in this study. Average germination percentages in osmotic environment treatments ranged from 63.3% to 94.7%, total root lengths were 10.54-23.12 cm, and shoot lengths were 4.73-10.56 cm. Seed vigor indexes ranged from 1392.4 to 3048.6, cell membrane damage ranged from 0.16% to 47.26%, and chlorophyll content varied between 0.005 and 0.101 mg mL-1 g FW-1. Kırmızı Yerli, Conkesme, and Türkmen were considered drought-resistant based on two out of the three parameters tested. In addition, Yakar 99, Pehlivan, İzgi 2001, İkizce 96, Mızrak, and Gerek 79 were considered drought-susceptible based on two out of the three parameters tested. Kırmızı Yerli, Conkesme, and Turkmen, which were notable in terms of both parameters, could be used as parents in breeding programs related to drought resistance.

In this study, three sowing times [winter sowing (first week of September), freezing sowing (last week of October) and spring sowing (last week of April)] at seven seeding rates (325, 375, 425, 475, 525, 575 and 625 seeds m−2) were investigated during the 2002–03 and 2003–04 seasons, in Erzurum (Turkey) dryland conditions, using Kirik facultative wheat. A split-plot design was used, with sowing times as main plots and seeding rates randomized as subplots. There was a significant year × sowing time interaction for grain yield and kernels per spike. Winter-sown wheat produced a significantly higher leaf area index, leaf area duration, spikes per square metre, kernel weight and grain yield than freezing- and spring-sown wheat. The optimum time of sowing was winter for the facultative cv. Kirik. Grain yields at freezing and spring sowing were low, which was largely th...

Plants can be exposed to drought from seeding to harvesting (Gunes et al., 2006). There are 2 main effects of drought on crop production: the prevention of seedling emergence and a decrease in development and yield. In the early stages of development, particularly in insufficient water conditions, it is important for plants to effectively use available soil moisture (Clarke et al., 1984; Acevedo, 1987; Richards, 1992). Drought in the early development stages causes earlier flowering and decreases in plant height, leaf area, and the number of fertile tillers (Day and Intalap, 1970; Robertson and Giunta, 1994). Even if sufficient soil moisture is supplied in the postflowering stage, drought prior to flowering lowers the grain-filling period and grain weight (Öztürk and Çağlar, 1999). Due to irregular and insufficient rainfall, drought can be experienced during the sowing period, emergence, and seedling development periods in dry farming areas of different geographical regions of the world (Adjei and Kirkham, 1980; El Hafid et al., 1998), including Turkey. It is important to have good and early seedling establishment for high yield and stable wheat production in dry farming conditions. Insufficient available water in the early development stages significantly constrains grain yield through decreasing germination, emergence, seedling development, and establishment (Blum et al., 1980; Naylor and Gurmu, 1990; Richards and Lukacs, 2002). For stable crop production, it is important to minimize yield loss due to stress factors. This can be done by selection or breeding plants resistant to stress factors. Several selection criteria were set to determine the best parents to use in breeding programs and to classify populations based on tolerance to drought in the early development stages (Gavuzzi et al., 1997; Dhanda et al., 2004). Coleoptile length (Rebetzke et al., 1999), seedling survival after drought (Winter et al., 1988), and seedling vigor (Rebetzke et al., 2004; Reynolds et al., 2006) measurements have been successfully used for selection of drought tolerant wheat genotypes in respected breeding programs.
