Öğe Combining ability of bean genotypes estimated by line × tester analysis under highly-calcareous soils(Pakistan Agricultural Scientists Forum, 2014) Ceyhan E.; Kahraman A.; Avci M.A.; Dalgiç H.Line × Tester analysis involving six lines (local populations viz., PV1, PV2, PV3, PV4, PV5 and PV6) and three testers (cultivars viz., Şehirali 90, Akman 98 and Yunus 90) of dry bean (Phaseolus vulgaris L.) was conducted to determine combining ability of seed yield and its related traits under highly calcareous soils. Significant differences of linextester interaction was observed for all characters under the study indicating the prevalence of non-additive variance. Similarly, less than one value of ?2gca/?2sca ratio for all traits indicated predominance of non-additive gene effects. Significant general and specific combining ability (GCA and SCA) effects were also noted in all the traits. Among the parents, PV5 (Line) and Akman 98 (Tester) were found to be good general combiners for seed yield and yield components. The most promising specific combinations for yield and other traits were PV3 ×Akman 98, PV2xYunus 90, PV6xŞehirali 90 and PV5xYunus 90. These crosses had significant estimates of SCA effects suggesting predominance of non-additive gene action for these traits under highly-calcareous soils. The average heterosis was 53.61% for seed yield. This study has shown that in order to improve seed yield and yield components in dry bean under highly calcareous soils, the selection of parents should be based on per se performance as well as combining ability.Öğe Correlations and genetic analysis of pod characteristics in pea (Pisum sativum L.)(2006) Avci M.A.; Ceyhan E.A line x tester analysis was carried out in pea to determine the genetic interaction in the expression of various pod characters including pod yield. Seven varieties were selected, four of them were designated as lines Sprinter, Manuel, Carina and Bolero and three of them were called as testers, B 1, B6 and B12 line. Combining ability studies were conducted on these parents along with their F1 hybrids for the variables pod yield, hundred seed weight, pods per plant, pod width, pod length and seeds per pod. While Sprinter, Manuel and B6 were best general combiners among the parents, Sprinter x B12, Manuel x B6 and Carina x B1 were the best crosses for pod yield. Correlation studies showed that the pod yield was significant positive correlated with pods per plant and hundred seed weight. The highest direct effect was exhibited by pods per plant, indirect effects, especially through the seeds per pod in pea. © 2006 Asian Network for Scientific Information.Öğe Effects of sowing dates and cultivars on protein and mineral contents of bean (Phaseolus vulgaris L.)(2008) Ceyhan E.; Harmankaya M.; Avci M.A.Six bean cultivars were grown at four different sowing dates for two years to study the effects of sowing date, genotypic and growing seasons on protein and mineral contents. The protein and mineral contents of bean are influenced by growing seasons, sowing date and genetic factors. This study investigated differences in protein and mineral contents in grains of six bean (Phaseolus vulgaris L.) cultivars. Protein content ranged 21.40-27.29 %, phosphorus 570.00-796.59 mg/100 g, potassium 1856.40-2159.24 mg/100 g, magnesium 174.56-197.95 mg/100 g, calcium 120.06-182.65 mg/100 g, sodium 45.57-51.89 mg/100 g, iron 6.50-8.41 mg/100 g and zinc 1.69-2.27 mg/100 g, respectively with significant differences among bean cultivars. The effects of years, sowing date, cultivars, year x cultivars interaction, year x sowing date interaction, cultivars x sowing date interaction and year x cultivars x sowing date interaction were highly significant, but the variation was mainly attributed to the environment and sowing date. In general, protein, phosphorus, potassium, calcium, sodium and iron content increased with delayed sowing. Unlike, the zinc content decreased with delayed sowing.Öğe Inheritance of some agronomic characters in pea [Bezelyede bazı agronomik özelliklerin kalıtımı](Ankara University, 2017) Şimşek D.; Ceyhan E.This study was conducted by using Jinks-Hayman type analyses on four pea genotypes (PS4009, PS3053, PS3073 and Reyna) and their population of the complete diallel reciprocal crosses in order to examine the genetic structure. According to the results of all diallel crosses, environmental variance (E) and additive gene variance (D) was not significant. All the features of the dominant gene variances were higher than the additive gene variances (H1) and D-H1 value was found to be negative. In the population, dominant genes were found significant for all the characteristics except number of seed per pod. Result of Wr, Vr graphics indicated partial dominancy for the number of seed per pod, and over dominancy for the rest of the characters studied. © Ankara Üniversitesi Ziraat Fakültesi.Öğe Line x tester analysis in pea (Pisum sativum L): Identification of superior parents for seed yield and its components(2008) Ceyhan E.; Avci M.A.; Karadaş S.This research was carried out to investigation the genetic structure of the 24 F1 pea hybrids established from eight exotic female lines and three local winter hardiness male testers, to determine parents showing general combining ability (GCA) and determine crosses showing specific combining ability (SCA.), and to evaluate the heterosis. Broad genetic variability was observed among the genotypes. Estimates of variance due to GCA and SCA and their ratio revealed predominantly non-additive gene effects for all studied traits. While PS9830S329 (female) and H (male) were the best general combiners among the parents, PS9830S329 × B12 was the best cross for seed yield. Hybrids generally showed greater yield potential than their parental genotypes. Heterosis was observed in some hybrids for each trait studied. © 2008 Academic Journals.Öğe Micronutrient contents in leaves of sunflower cultivars grown with different boron doses(2010) Öztürk Ö.; Ceyhan E.; Önder M.; Harmankaya M.; Hamurcu M.; Gezgin S.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 O, 2.5, 5.0, 7.5 and 10.0 kg B ha -1 (applied as a spray of boric acid, H 3BO 3) 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.Öğe Nutritional variation and drought tolerance in chickpeas (Cicer arietinum L.)(Polish Society Magnesium Research, 2015) Kahraman A.; Ceyhan E.; Harmankaya M.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. © 2015, Polish Society Magnesium Research. All rights reserved.
