    ANALYSIS OF ONOBRYCHIS GENETIC DIVERSITY USING SSR MARKERS FROM RELATED LEGUME SPECIES
    (Pakistan Agricultural Scientists Forum, 2014) Avci, S.; Ilhan, E.; Erayman, M.; Sancak, C.
    Availability of legume microsatellite markers for Onobrychis taxa was limited. However, cross genera utilization of such markers has been of great interest due to the high cost and labor. In the present study, we attempted to transfer microsatellite markers from Phaseolus vulgaris L. and Medicago truncatula Gaertn. to Onobrychis genus. Additionally, transferred markers were used to identify genetic diversity among Onobrychis taxa collected from different regions of Turkey. Of the 95 SSR primer pairs previously used for P. vulgaris and M. truncatula, 18 primers were successfully amplified and showed polymorphism among 58 Onobrychis taxa. Eighteen SSR primers observed 79 loci resulting in 725 alleles. The highest number of loci was obtained from BM175 and MTIC84 primers. Gene diversity and polymorphism information content values showed that P. vulgaris primers produced the most informative loci on Onobrychis genomes. The highest genetic diversity values were obtained for Onobrychis argyrea Boiss. subsp argyrea Boiss. (53) while the lowest from Onobrychis cornuta (L.) Desv.(1). The average diversity values were the highest on Hymenobrychis section which was followed by Heliobrychis, Onobrychis, Laphobrychis and Dendobrychis sections. Magnitude of genetic variation was the highest within Onobrychis section in which genetic similarity values ranged from 0.013 to 0.399. The SSR and phylogenetic analysis results showed that sections were separated similar to their morphological characteristics. However, Hymenobrychis and Heliobrychis clearly separated from other sections. Our study showed that Onobrychis genomes could be successfully studied using other legume SSR markers. Therefore, they can be used for conservation of Onobrychis species as well as improving new varieties for feed use.

    Estimates of relative yield potential and genetic improvement of wheat cultivars in the Mediterranean region
    (Cambridge Univ Press, 2009) Sener, O.; Arslan, M.; Soysal, Y.; Erayman, M.
    Information about changes associated with advances in crop productivity is essential for Understanding yield-limiting factors and developing new strategies for future breeding programmes. National bread wheat (Triticum aestivum L.) yields in Turkey have risen by an average of 20.8 kg/ha/year from 1925 to 2006. Annual gain in yield attributable to agronomic and genetic improvement averaged c. 11.6 kg/ha/year prior to 1975, but is now averaging c. 15.1 kg/ha/year. In the Mediterranean region, however, the wheat yield trend line (10.9 kg/ha/year) is c. 0.38 lower than that of Turkey. In order to understand whether such a trend was due to the cultivars released over the years. 16 bread Wheat cultivars, commonly grown in the region and representing 23 years of breeding. introduction and selection (from 1976 to 1999), were grown in a randomized complete block design with three replicates across 2 years. Data were collected on Maturation time, plant height. spike length, spikelet number/spike, grain number/spike, grain weight/spike. 1000 seed weight. harvest index and grain yield. None of the Measured plant traits showed ally historical cultivar patterns therefore, the increase in grain Yield Could not be attributed to a single yield component. Several physiological traits changed during two decades of cultivar releases in the Mediterranean region that led to a genetic gain in grain yield of about 0.5% per year. Years of data and the present field study in the Mediterranean region suggested that the genetic improvement in wheat seemed inadequate and should be reinforced with modern agricultural management practices as well as technological innovations.

    Twin or narrow-row planting patterns versus conventional planting in forage maize production in the Eastern Mediterranean
    (Akademiai Kiado Zrt, 2008) Yilmaz, S.; Erayman, M.; Gozubenli, H.; Can, E.
    Producing forage maize (Zea mays L.) in twin-row planting pattern has been attempted in past years. This research was performed to determine effects of planting patterns and densities on yields of forage maize hybrids. We also examined other plant characteristics associated with forage yield under second crop conditions in Hatay, East Mediterranean region of Turkey, during 2003 and 2004. The experimental design was a randomized complete block design in a split-split-plot arrangement with three replications. The planting patterns of twin row (55:20 cm), conventional row (75 cm) and narrow row (50 cm) were main plots, the plant densities (80,000, 100,000 and 120,000 plants ha(-1)) were split-plots, and the hybrids (PR-1550, MAVERIK and DK-585) were split-split plots. Forage and dry matter yields were significantly affected by planting patterns, plant densities and maize hybrids. Our results revealed the advantage of twin-row planting pattern over conventional and narrow row plantings at all plant densities. Twin row planting out-yielded conventional row (16% more forage and 10.2% more dry matter yield) and narrow-row (7.9% more forage and 5.9% more dry matter yield) plantings. Twin-row planting pattern may be a profitable production technique for forage maize producers.
