    Determining the performance of alfalfa population collected from a narrow agroeceological zone of Turkey
    (Univ Federal Santa Maria, 2020) Cacan, Erdal; Kokten, Kagan; Seydosoglu, Seyithan
    This study was carried out to determine the yield and quality characteristics of some alfalfa village populations cultivated by producers in Bingol province of Turkey. Alfalfa seeds were obtained from 23 different locations in 2015. A three replicated, randomised complete block designed field trial was established in 2016 including these genotypes and four registered varieties. As a result of three year trials, it was determined that the populations obtained from the villages of Servi, Mutluca, Garip, Saricicek-1 and Bagliisa produced highest green herbage and hay yields. When we compare the quality results, Kumgecit, Kucuktekoren and Senkoy-1 populations stands out in terms of crude protein ratio. Highest crude protein yield was obtained from Servi population. In terms of relative feed value, it was observed that the varieties were better qualfied than the populations. It is concluded that the populations of Servi, Mutluca, Garip, Saricicek-1 and Bagliisa can be used in breeding studies especially to obtain genetic progress in yield of alfalfa for feed and bioenergy production. For the genetic improvement of current genotypes with higher crude protein ratio, Kumgecit, Kucuktekoren and Senkoy-1 populations can be used as a source. This study showed that, East Anatolia region is not just live-conserving highly diversified species but also covering special intra-species genetic diversity in microclimatic zones of Turkey to be used to improve the global forage and bioenergy cropproduction.

    GENETIC VARIABILITY FOR SEED NUTRITIONAL COMPOSITION IN PEARL MILLET GENOTYPES ANALYZED BY BIPLOT METHOD
    (Univ Quindio, 2023) Seydosoglu, Seyithan; Kokten, Kagan; Cil, Abdullah; Turan, Nizamettin
    This study evaluated the chemical composition of pearl millet seeds belonging to different genotypes by biplot analysis. Seeds of 26 different pearl millet populations obtained from ICRISAT (International Crops Research Institute for the Semi-Arid Tropics) within the scope of TuBITAK 219O103 run by Sirnak University were used. The seeds were ground and analyzed for their chemical composition, i.e., acid detergent fiber (ADF), neutral detergent fiber (NDF), crude protein (CP), digestible dry matter (DDM) and dry matter intake (DMI) rate. The results revealed that crude protein ratio varied between 11.74-19.24%, whereas ADF ratio differed between 3.44-11.43%. Similarly, NDF ratio varied between 10.23-23.47%, while DDM ratio ranged between 79.98-86.21%. Likewise, DMI ratio differed between 5.11-11.72%. Scatter plot obtained after biplot analysis indicated three different groups based on the analyzed traits. The first group contained DDM and DMI, whereas the second group consisted of ADF and NDF. The protein ratio was in the third group. It was determined that ADF-NDF and DMI-DDM properties were negatively correlated with each other. According to biplot, genotypes 'A5-13', 'A13-6' and 'B1-7' were prominent for ADF-NDF, DMI-DDM, and protein ratio, respectively. Therefore, these genotypes can be used in future studies to induce the desired traits.

    Status and health of some natural pastures in south east Anatolia region of Turkey
    (Range Management Soc India, 2019) Seydosoglu, Seyithan; Kokten, Kagan; Saruhan, Veysel; Sevilmis, Ugur
    To study the status and health of pastures in Derik district of Mardin province in south east Anatolia region, seven natural pastures were surveyed by modified wheel point with loop. Total of 45 plant species were recorded in studied pastures. The study was carried out during May and June 2015. Plant species were divided into three different groups: decreasers, increasers and invaders according to the palatability of the plant species for the grazing animals. Average vegetation cover ratio was found as 70.0%. Plant cover percentages of grasses, legumes and other family plants in the total plant cover were 21.53%, 29.19% and 49.28%, respectively. Invasive species were found dominant in these studied pastures. Thus pastures of Mardin province were highly degraded, and sustainable management and rehabilitation techniques need to be urgently applied to stop this on-going continuous degradation.
