32 Turkish corn accessions representing different climatic, geographic and topographic areas in Turkey were identified. Genetic variation and its pattern in three corn races (pop, flint and dent) included 32 accessions were investigated using 25 morphological and agronomic traits. Vegetative, ear and kernel related traits were significantly varied both among races and accessions within races. Variance component due to races and accessions within race were statistically significant, but the variance components due to accessions were generally made up large component of total variance and ranged from 17.17% in kernel length to 82.75% in tassel length. There were also strong and mostly positive correlations between studied agronomic traits as well as between agronomic traits and isoenzyme loci. These correlations were explained by the traditional farming practices and enzyme specificity with flint accessions since the enzyme systems such as Alcohol dehydrogenase (locus 1), Malate dehydrogenase enzyme (loci 2-3) and 6-phospho-gluconate dehydrogenase (locus-1) are generally considered to be the characteristics of flint corn race. Canonical discriminant function analysis with twenty-five morphological and agronomic traits revealed that first two canonical discriminant variables explained 68% of total variation among accessions. Two Canonical variables, in which kernel related traits were heavily weighted, correctly classify the three corn races indicating that Turkish corn accessions maintained their racial characteristics with agronomic and morphological traits.


Genetic relationships among perennial and annual Cicer species growing in Turkey as revealed by allozymes
Sudupak, MA; Kence, Aykut (Springer Science and Business Media LLC, 2004-05-01)
Allozyme polymorphisms were used to assess genetic variation and relationships among ten Cicer species ( annuals and perennials) growing in Turkey. Using seven enzyme systems, 12 putative scorable loci were detected and surveyed for polymorphism in an accession collection including wild and cultivated forms. Variation was generally low within accessions and species, but common between species. Cluster analysis based on the pairwise genetic distance coefficients (Nei 1978) among accessions and species using ...
Genetic relationships among perennial and annual Cicer species growing in Turkey assessed by AFLP fingerprinting
Sudupak, MA; Akkaya, Mahinur; Kence, A (Springer Science and Business Media LLC, 2004-03-01)
AFLP markers were used to assess genetic relationships among Cicer species with distribution in Turkey. Genetic distances were computed among 47 Cicer accessions representing four perennial and six annual species including chickpea, using 306 positions on AFLP gels. AFLP-based grouping of species revealed two clusters, one of which includes three perennial species, Cicer montbretii, Cicer isauricum and Cicer anatolicum, while the other cluster consists of two subclusters, one including one perennial, Cicer ...
Genetic variability among Turkish pop, flint and dent corn (Zea mays L. spp. Mays) races: Enzyme polymorphism
Ilarslan, R; Kaya, Zeki; Tolun, AA; Bretting, PK (2001-01-01)
To determine magnitude and pattern of genetic variation, 32 Turkish corn accessions available from the USDA/ARS North Central T-Regional Plant Introduction Station (NCRPIS) collections (Ames, Iowa), representing pop, flint and dent corn races, different climatic, geographic and topographic areas in Turkey, were identified and, 19 isozyme systems were studied. Thirty-nine alleles were detected by 19 isozyme loci in 32 accessions. The PGD-2, Mmm-1, GOT-3 and IDH-1 loci were found to be monomorphic in all acce...
Genetic diversity and structure of Populus nigra populations in two highly fragmented river ecosystems from Turkey
Çiftçi, Asiye; Kaya, Zeki (Springer Science and Business Media LLC, 2019-08-01)
European black poplar (Populus nigra L.) is an important tree species in terms of social, economic, and ecological interest in Turkey. Although large poplar plantations meet the needs of the economy, natural genetic resources of the species have been highly degraded due to anthropogenic effects such as overexploitation and habitat fragmentations. To assess genetic diversity and structure of fragmented populations, 124 naturally distributed European black poplar trees from two major rivers (Kızılırmak and Gö...
Polymorphism of Prolactin (PRL), Diacylglycerol Acyltransferase (DGAT-1) and Bovine Solute Carrier Family 35 Member 3 (SLC35A3) genes in native cattle breeds and its implication for Turkish cattle breeding
Kepenek, Eda Şeyma; Togan, İnci Zehra; Department of Biology (2007)
In the present study samples from four native Turkish Cattle Breeds; South Anatolian Red (n= 48), East Anatolian Red (n= 34), Anatolian Black (n= 42) and Turkish Grey (n=46) and elite bulls of Holstein (n=21) were genotyped with respect to two milk production enhancer genes, Prolactin (PRL) and Diacylglycerol acyltransferase (DGAT1), and one disease (Complex Vertebral Malformation) causing gene (SLC35A3). A allele frequency for PRL gene, believed to be positively associated with the milk yield in cattle, ra...
