Performance of Local Bean (Phaseolus vulgaris L.) genotypes for breeding potential under unheated greenhouses using phenological and morphological characterization Tugce Yayla, Rajneesh Kumar, Ajaz Ahmad Lone, Faik Kantar, Mehdi Rahimi Discover Life, 2026 This study aimed to assess the plant performance and cold tolerance of 12 local bean (Phaseolus vulgaris L.) genotypes including eight pure lines and four selected genotypes, under unheated greenhouse conditions, compared with the commercial cultivar HELDA. In addition, phenological and morphological observations were conducted for 41 traits in accordance with the UPOV and TTSM Bean Trait Certificate rules for four genotypes. For local genotypes, research was carried out on flowering time, pod width, thickness, length, and weight; pod number; yield per plant; seed number and yield per plant; and plot seed yield. Cell electrolyte leakage and chlorophyll fluorescence measurements were made to investigate cold tolerance. Results for pod length, BN-23, and HK-38 showed that the local genotypes had the most extended pod length, at 21.30 and 20.53 cm, respectively. GV-41 and HK-38 were superior to the commercial cultivar HELDA, with pod widths of 27.9 and 26.42 mm, respectively. While pod weight ranged from 9.05 g to 28.33 g for local genotypes, GV-41 had the highest pod weight (28.33 g). In terms of efficiency, GV-41, ANTO, and BN-23 stood out. Regarding cold tolerance, no significant change was observed. The high air temperatures may explain the observed results. Compared with the commercial cultivar HELDA, four local genotypes, BN-23, HK-38 and VN-16, showed promising phenological and morphological traits, making them suitable candidates for fresh bean and kidney bean breeding programs.
Seed Oil Contents, Fatty Acid Compositions, and Gossypol Concentrations of Some Okra Landraces Faik Kantar, Mehmet Fatih Cengiz, Sabri Erbaş, Ümit Babacan Food Science and Nutrition, 2024 Okra has recently attracted attention owing to its superior tolerance to high temperatures, greater adaptation to poor soil conditions, and having a robust plant structure. The plant contains a high amount of oil and valuable fatty acids; however, the main restriction of using okra seeds as an oil crop results from its gossypol contents. The aim of this study was to determine the oil content of okra landraces and to evaluate its potential as an oil crop. For this aim, seed oil content, fatty acid compositions of cold‐pressed seed oil, and gossypol concentrations of fruit, oil cake, and seed oil were investigated in a core collection of 26 okra landraces, lines, and cultivars. Individual plants were harvested at the full maturity stage, and seeds were harvested and dried under 35°C for 2 days prior to oil extraction. Oil content, fatty acid composition, and gossypol content were analyzed by NMR, GC‐FID, and HPLC, respectively. The calibration coefficients (r2) of all the methods were determined to be > 0.99. The seed oil content of the samples ranged between 12.15% and 18.83%. Linoleic (42.01%), palmitic (31.65%), oleic (18.39%), and stearic acids (3.20%) were found to be the largest fraction of the fatty acids. The data matrix from 19 fatty acids and oil content was subjected to Principle Component Analysis (PCA). As a result, 6 principal components (PCs, eigenvalues > 1) explained 83.84% of total variance in the data set, with PC1 contributing 32.69% of the total. Gossypol contents of the fruit, oil cake, and seed oil fractions ranged between LOQ‐2.12, < LOQ‐7.01, and < LOQ‐62.46 mg/kg, respectively. In conclusion, okra may have the potential to be an alternative oil crop for food/feed purposes due to the presence of reasonable oil content, high‐quality fatty acid variations, and very low amounts of toxic gossypols, warranting further breeding and agronomic studies.
MOLECULAR CHARACTERIZATION OF COLD TOLERANT GERMPLASM OF PHASEOLUS BEANS WITH SEQUENCE RELATED AMPLIFIED POLYMORPHISM (SRAP) AND RETROTRANSPOSON-BASED INTERPRIMER BINDING SITES (iPBS) MARKERS B.T. Certel, Hatice İkten, Yusuf Yılmaz, Faik Kantar, Vahdettin Çi̇ftçi̇, et al. Journal of Animal and Plant Sciences, 2023 In this study genetic diversity of 55 Phaseolus sp. beans selected for cold tolerance from different regions of Türkiye was investigated by using sequence related amplified polymorphism (SRAP) and retrotransposon-based interprimer binding sites (iPBS)markers. Four commercially registered cultivars, one accession of Phaseolus coccineus and a tepary bean Phaseaolus acutifolius species were included for comparison. Genomic DNA was isolated from young fresh leaves and PCR reaction was carried out using 30 SRAP (sequence related amplified polymorphism) and 12 iPBS (retrotransposon-based interprimer binding sites) primers. Similarity analyses were performed and dendrograms were produced according to the Unweighted Pair-Group Mean Arithmetic method (UPGMA). In PCR reactions, 331 total and 146 polymorphic bands were produced with 30 SRAP primer combinations. The number of polymorphic bands ranged between 1 and 12 with an average 4.86 polymorphic marker for each primer pair. Twelve iPBS primers produced 156 total bands and 72 of them were polymorphic. The highest polymorphism was obtained with SRAP primer combinations of Me8Em3 and Me7Em14 and iPBS primers 2270, 2394 and 2252. Characterization of germplasm with SRAP and iPBS primers was discussed in relation to cold tolerance, species, source, seed size, seed color and growth type. In conclusion, genetic variability of germplasm of 55 Phaseolus bean species, genotypes and cultivars selected for cold tolerance were effectively assessed by PCR based molecular techniques, SRAP and iPBS. High levels of polymorphism determined in the core collection may be used in breeding programs for the development of cold tolerant superior cultivars. Key words: Phaseolus sp.

Identification of resistance sources in common bean (Phaseolus vulgaris) genotypes from Turkey and the reactions of some promising genotypes to bean anthracnose (Colletotrichum lindemuthianum) Gülsüm Palacıoğlu, Mehmet Zahit Yeken, Faik Kantar, Hüseyin Çancı, Vahdettin Çiftçi, Harun Bayraktar, Göksel Özer Crop and Pasture Science, 2022 Context Among biotic factors, bean anthracnose caused by Colletotrichum lindemuthianum (Sacc. & Magnus) Briosi & Cavara is one of the most destructive diseases of common bean (Phaseolus vulgaris L.). Resistance in common bean genotypes is controlled by anthracnose resistance loci (designated Co). Aims The objective of this study was to evaluate the presence of Co resistance genes in common bean genotypes from Turkey and to examine promising genotypes as candidates for parent plants in breeding studies. Methods The presence of Co resistance genes in 693 common bean genotypes from 35 provinces of Turkey was determined by 12 SCAR (sequence characterised amplified region), RAPD (random amplified polymorphic DNA), STS (sequence-tagged site) and CAPS (cleaved amplified polymorphic sequence) markers. The disease reaction of 40 agronomically promising genotypes to different pathogen isolates was evaluated in a pot study. Key results The results indicated the presence of Co-1, Co-14, Co-15, Co-2, Co-33, Co-4, Co-42, Co-6, Co-10, Co-11 and Co-13 resistance genes, alone or in combination; Co-5 was not detected in any of the genotypes. Among the genotypes, Co-15 was the most frequent resistance source, followed by Co-4, Co-6 and Co-11, respectively. Common bean genotypes carrying Co-14, Co-2, Co-33, Co-11 and Co-13 have been identified for the first time in Turkish germplasm. Five genotypes carrying the various combinations of Co-1, Co-15, Co-4, Co-6, Co-10, Co-11 and Co-13 were resistant to all isolates in pathogenicity tests. Conclusions This study is the most comprehensive to date on Co genes linked to the resistance of common bean genotypes throughout Turkey and provides an important gene pool for breeding studies into bean anthracnose. Resistant genotypes identified will be useful as parent plants in resistance breeding studies. Implications Resistance genotypes carrying different Co genes to bean anthracnose will contribute significantly to the disease management strategy.
Emergence, photosynthesis, and seedling growth of bean genotypes, as affected by salt sources and salinity levels Mulat Asmamaw, Ahmet Kurunc, Kivanc Hayri Doganay, Faik Kantar, Nurlykhan Bimurzayev Journal of Crop Improvement, 2022 The type and amount of salt present in water determine the suitability of water for irrigation. The aim of this study was to determine the effects of different salt sources (SS) and different salinity levels (SLs) in irrigation water on photosynthetic capacity, emergence and seedling growth parameters of eight bean (Phaseolus vulgaris L.) genotypes (G). The experiment was designed as a three-factorial split–split plot under a rain-out shelter. The G × SS × SL interaction for all investigated parameters was statistically significant. In general, GV-51, VN-50 and ML-34 genotypes were not adversely affected by increasing SL with respect to CaCl2, MgCl2 and CaSO4 salts. However, compared to the control, VN-8 and TR-64995 genotypes showed the lowest percent emergence from 2 and 3 dS m−1 with all salt sources, except VN-8 with CaSO4 salt. None of the genotypes showed significant differences for mean emergence time with increasing SL of CaSO4 salt. The highest shoot length was obtained for Helda genotype under control SL. Considering all genotypes, the values ranged from 0.533 to 0.740 for Fv/Fm ratio, 3.36 to 3.38 g for biomass weight, 1.82 to 4.75 g for shoot weight, and 1.42 to 4.50 g for root weight. Genotypic differences existed for salinity tolerance for emergence and early seedling growth, and the effects of salinity depended not only on the amount of salt but also on the kind of salt present in the irrigation water.
Phenotypic and iPBS-retrotransposon marker diversity in okra (Abelmoschus esculentus (L.) Moench) germplasm Faik Kantar, Sevde Nur Yemşen, Cansu Bülbül, Neslihan Yılmaz, Nedim Mutlu Biotech Studies, 2021 This study was undertaken to assess genetic and phenotypic diversity of Turkish okra (Abelmoschus esculentus (L.) Moench) germplasm of 26 landraces including three cultivars (Akköy-41, Kabaklı-11, and Marmara-1) with 34 phenotypic traits and 74 iPBSretrotransposon primers. Leaf-blade size, fruit length, fruit diameter, fruit number per plant, petiole length, plant height, stem diameter, number of stem nodes, and plant growth type (degree of branching) were the most important morphological traits contributing to the variation. Comparison of genotypes with 14 iPBS-retrotransposon primers yielded 141 bands, 34 of which (24.1%) were polymorphic, with the primer 2271 producing the highest (6) bands per primer. Cluster analysis based on phenotypic and molecular markers produced two major groups. Phenotypic based unweighted pair group method with arithmetic mean (UPGMA) dendrogram had 12 sub-groups with the highest similarity (0.63) between GAN-19/GAN-21 and MGL-6/Akköy-41 genotypes. The markers, however, produced a dendrogram with eight subgroups, pairwise genetic similarities ranging from 0.43 to 1.00, where MGL-6 singled out with a similarity value of 0.57. Howbeit, the Mantel test between both dendrograms based on the similarity matrix was insignificant.

Effect of Bacillus subtilis and Bacillus amyloliquefaciens culture on the growth and yield of off-season potato (Solanum tuberosum L.) Faik Kantar, Aysel Uysal Acta Agronomica, 2020 A study was carried out in order to investigate the effect of microbial fertilizer application on off-season potato (Solanum tuberosum L. cv. Universia) under field conditions in early spring and late autumn in 2016. The experiment included Control (C, no application), Standard Fertilizer Application (SFA), Microbial Fertilizer Application (MFA) and SFA+MFA treatments. An equal mixture of three strains of Bacillus subtilis VKPM B-10641(DSM 24613), Bacillus amyloliquefaciens VKPM B-10642 (DSM 24614) and Bacillus amyloliquefaciens В-10643 (DSM 24615) was applied at 1x109 cfu/ml to tubers before planting and to plants at flowering stage in MFA and SFA+MFA plots. Treatments affected the plant growth parameters. SFA plots produced the highest tuber yields in both seasons. MFA plots had earlier emergence time (40 days), higher number of stems per plant (3), higher number of leaves per plant (37.2), thicker stem diameter (10.15 mm), higher above ground biomass yields (5.42 t/ha), higher single tuber weight (104.21 g) and higher tuber yields (22.06 t/ha) compared with control plots (42 days, 2.2, 31.2, 9.15 mm, 4.40 t/ha, 90.88 g and 20.14 t/ha respectively). Tuber yield in MFA plots (26.56 t/ha) was equal to SFA plots (26.81 t/ha) in warmer autumn planting. Combination of SFA and MFA produced lower tuber yields (21.72 t/ha) than SFA treatment (26.81 t/ha). In conclusion, Bacillus subtilis and Bacillus amyloliquefaciens gave comparable tuber yields to chemical fertilizer application in warmer autumn plantings, but lower tuber yields in colder spring conditions warranting further experiments with cold tolerant psychrophilic bacterial strains for off-season potato production.
