Background: Common bacterial blight (CBB) caused by Xanthomonas axonopodis pv. phaseoli (Xap) has been recorded as one of the most important seed-borne destructive diseases of beans, affecting its production worldwide. Since chemical compounds cause serious damage to natural ecosystems and in some instances fail in controlling CBB, the use of genetically resistant cultivar is the most economically efficient and environmentally friendly measure in the control of CBB disease. The objective of this study was to assess the resistance reactions of widely grown and popular common bean cultivars against Xap under controlled conditions. Methods: In this study, 16 dry bean cultivars comprising eight widely grown dry bean varieties, six improved and promising genotypes and two known CBB susceptible varieties, were evaluated for their reaction to the CBB in a completely randomized design with three replications. The reaction of the bean cultivars to Xap was assessed using disease incidence, disease severity, per cent severity index, the area under disease progress curve (AUDPC) and incubation period. Result: Data analysis indicated that there were highly significant differences (p≤0.01) among common bean cultivars for CBB disease incidence, disease severity, per cent severity index and AUDPC among cultivars. The cultivated varieties Noyanbey and Özmen were identified as resistant cultivars. In addition, SAP6 and BAC6 resistance genes were found in these two cultivars. As a consequence, it was thought that these cultivars could be a potential source of disease resistance for CBB in breeding programs and sustainable, eco-friendly and good agricultural practices.

Chemical properties, mineral content and amino acid composition of three cowpea genotypes (Karagoz, Samandag and Sarikiz) were determined. Almost all investigated characteristics (except for potassium, sulphur, copper, proline, and sarcosine) were revealed to be statistically important. Chemical properties of cowpeas showed that protein ranged from 27.6 to 30.1%, carbohydrate 56.3-60.0%, ash 3.8-4.2%, fat 2.0-2.3% and moisture 5.9-7.2%. The amounts of potassium, phosphorus, calcium, sulphur, magnesium, iron, zinc, manganese and copper were adequate to meet macronutrient and micronutrient demand in human diets. The ratios of 22 amino acids showed that methionine, tryptophan and tyrosine amino acids were limiting components. According to the results, the cowpea genotypes were rich in the essential amino acids and chemical composition.

Drought stress decreased leaf water absorption capacity and real water content and increase relative water content in genotypes of chickpea. It decreased chlorophyll a and b content. Drought increased peroxidase superoxide dismutase, glutathione reductase, ascorbate peroxidase and catalase in stress groups. Proline content increased drastically index stress condition.

Pulses are an important dietary constituent in human and animal diets. As well as being a source of income and livestock feed, pulses satisfy 33% of the dietary protein nitrogen (N) needs of humans. Pulses are often exposed to environmental stresses (biotic and abiotic) that decrease their productivity throughout the world. Abiotic stresses (drought, salt, temperature, UV, nutrient deficiency) alone are responsible for more than 50% yield reductions of some major crops. The following examination of drought stress types (no irrigation, early period stress, late period stress, control) of 10 chickpea genotypes from Turkey was carried out for two years (2010 and 2011) in a field experiment set up accoding to a randomized complete block design with three replications and conducted under the ecological conditions prevalent in Konya, Turkey. The investigated nutrition-related parameters were the seed concentrations of protein, fat, ash, fiber, moisture, non-nitrogenous pith substances and minerals. Means achieved under the particular stress types showed that the protein percentage ranged from 19.71% to 19.80%, fat – 4.640 to 4.690%, ash – 2.810 to 2.860%, fiber – 7.360 to 7.400%, moisture – 9.150 to 9.180%, non-nitrogenous pith substances – 56.16 to 56.25%, while the mineral content (mg kg-1) corresponded to the following ranges: 9.700 to 9.980 B, 68.32 to 79.44 for Fe, 8866.3 to 8912.4 for K, 1383.1 to 1410.3 for Mg, 21.99 to 23.85 Mn, 3148.0 to 3192.6 P, 1815.6 to 1835.4 for S and from 25.81 to 28.43 for Zn. In general, the content of protein, magnesium and sulfur showed the lowest values under no irrigation conditions, while the content of ash, non-nitrogenous pith substances, boron, potassium, phosphorus and zinc showed the highest values under no irrigation conditions. Additionally, the nutritional value of chickpea seeds showed significant differences for all of the investigated characteristics viewed in terms of triple interactions (year x stress factor x genotype). The present research results can be useful for farmers, plant breeders, food companies etc., interested in chickpea. Finally, responses of the genotypes to different levels of drought stress were modified by the investigated quality characteristics. key words: mineral, nutrition, quality, seed composition, stress. dr Ali Kahraman, Department of Field Crops, University of Selcuk, Konya, Turkey, e-mail: kahramanali@selcuk.edu.tr

Bean is one of the most consumed pulse crops in the world. Hence, the quality of the protein and mineral content is important for producers and consumers. Line × tester methods were used to determine the combining ability and heterosis of protein content and mineral accumulation in common beans that were crosses of PV1, PV2, PV3, PV4, PV5, PV6, Sehirali 90, Akman 98, and Yunus 90. Mean squares of line × tester interactions were significant for all of the investigated traits and indicated the prevalence of nonadditive variance; moreover, the value of the s²gca/s²sca ratio for all characters was less than 1 and indicated predominance of nonadditive gene effects. Line × tester analysis revealed significant general combining ability and specific combining ability (SCA) effects for all the traits. Among the parents, PV2 and Yunus 90 were found to have high general combining abilities for protein and minerals. The most promising specific combiners for protein and minerals were from crosses PV1 × Akman 98, PV2 × Akman 98, and PV5 × Yunus 90. The average heterosis for protein was -0.70% in the F1 generation. The crosses PV1 × Akman 98, PV2 × Akman 98, and PV5 × Yunus 90 for protein content had significant estimates of both SCA effects and heterosis, suggesting the predominance of nonadditive gene action for the trait in these crosses. Additionally, only potassium content showed significant differences among the bean lines, while the testers exhibited nonsignificant differences for all of the investigated features. Analysis of the data indicated that the selection of parents should be based on per-seed content, as well as combining ability and heterosis, in order to improve protein and mineral contents in the common bean.

SUMMARY Although boron is essential for crop growth, the amount required differs among plant species. Sunflower (Helianthus annuus L.) requires greater quantities of boron to satisfy its metabolic needs than other cultivated species. The present work was undertaken to evaluate what effects five boron doses of 0, 2.5, 5.0, 7.5 and 10.0 kg B ha-1 (applied as a spray of boric acid, H3BO3) would have on micronutrient contents in leaves of four sunflower cultivars grown in B-deficient calcareous soils (0.19 B mg kg-1) during the 2001 growing season. Boron (B), iron (Fe), manganese (Mn), zinc (Zn) and copper (Cu) concentrations were measured in sunflower leaves at the flowering stage. According to the results, the B concentration in the leaves was highly correlated with boron doses, that is, the leaf B content increased in accordance with increasing B doses applied to the soil. Fe, Mn, Cu, and Zn concentrations in the leaves were not changed by the different B levels. However, leaf Mn, B and Cu concentrations varied with the cultivars. Among the cultivars, TR-4098 had the highest Mn (90.74 mg kg-1) and Cu contents (45.95 mg kg-1), while AS-615 had the highest B (83.52 mg kg-1) and Fe (202.55 mg kg-1) concentrations.

Abstract This study was conducted to investigate the effects of four boron (B) doses (control, 0 kg B ha−1; B1, 1 kg B ha−1; B2, 3 kg B ha−1; and B3, 6 kg B ha−1) in soils deficient in available B (0.19 mg B kg−1) and lime (CaCO3) content (20.7%) on yield and some yield components of five chickpea (Cicer arietinum L.) genotypes, namely Akçin‐91, Population, Gökçe, İzmir‐92, and Menemen‐92 in central Anatolian Turkey in the 2002 and 2003 growing seasons. Plant height, pods per plant, grain yield, protein content, protein yield, thousand seed weight, and leaf B concentration were measured. Grain yields in all genotypes (except for Gökçe) were significantly increased by 1 kg ha−1 B application. Application of 1 kg ha−1 B increased the yield by an average of 5%. Genotypes studied showed significant variations with respect to their responses to additional B. Akçin‐91 gave the highest grain yield (1704.8 kg ha−1) at 3 kg B ha−1, whereas Population, İzmir‐92, and Menemen‐92 yielded best (1468.2 kg ha−1, 1483.0 kg ha−1, and 1484.7 kg ha−1, respectively) at 1 kg B ha−1. Interestingly, Gökçe reached to the highest level of grain yield (1827.1 kg ha−1) at the control. Gökçe was a B deficiency B tolerance genotype. The other genotypes appeared to have high sensitivity to B deficiency. This study showed that B deficiency could result in significant yield losses in chickpea under the experimental conditions tested. Thus, B contents of soils for the cultivation of chickpea should be analyzed in advance to avoid yield losses.
