Bazı Arpa (Hordeum vulgare L.) Genotiplerinin Edirne Koşullarında

This research was carried out to determine of yield and some agronomic characters of some barley genotypes which was developed by Trakya Agricultural Research Institute and Bulgaria Karnobat Research Institute. The experiments were set up with 25 barley genotypes in completely randomized blocks design with four replications during 2006-2007 and 2007-2008 growing years in the experimental field of Trakya Agricultural Research Institute. The characters such as grain yield, plant height, spike length, heading and maturating days and grain number per spike and correlation among these traits were investigated. The results of the study showed that there were significant differences among the genotypes based on investigated characters. The mean grain yield of the genotypes was 647,4 kg/da. The highest grain yield (764,9 kg/da) was computed in TEA1500-22 line. In Trakya region, earliness is very important to production second crops in one growing season. The early heading genotype was TEA1525-25 line, while DRT136 was the latest heading line. Plant height is another important traits especially for lodging resistance in barley, and plant height ranged between 91,8 cm and 101,4 cm in the genotypes. The shortest plant height was measured in Veslets, TEA1535-21 and Sladoran. The spike length ranged between 6,8 cm and 9,9 cm in genotypes. Grain number per spike was 57,8 in the genotypes with 6 rows and, 27,7 grain in genotypes with 2 rows. The significant and negative correlation coefficient was determined between grain yield with spike length (r=-0,563) and days of heading (r=-0,718) in genotypes which has two rows spike type. The significant and positive correlation was determined between grain yield grain and grain number per spike (r=0,740). It was found that genotypes with early maturing gave higher grain yield than the others.

Bazı Yulaf (Avena sativa L.) Genotiplerinin Tane Verimi, Kalite ve Tarımsal Özelliklerinin Belirlenmesi

Bu calisma, Trakya Tarimsal Arastirma Enstitusunun islah calismalari sonucu gelistirilen yulaf genotiplerinin tane verimi, bazi kalite ve tarimsal ozelliklerinin belirlenmesi amaciyla 2012-2013 uretim yillarinda Edirne ve 2013–2014 uretim sezonunda Edirne ve Kirklareli lokasyonlarinda Tesaduf Bloklari Deneme Desenine gore dort tekerrurlu olarak yurutulmustur. On alti yulaf genotipinin kullanildigi denemede, bes standart cesit (Checota, Kirklar, Kahraman, Sebat ve Y-330) yer almistir. Genotiplerin tane verimi, bitki boyu, olgunlasma suresi ile kalite ozelliklerinden bin tane agirligi, hektolitre agirligi, protein orani, ic orani, kavuz orani ve elek analizi incelenmistir. Incelenen ozellikler yonunden genotipler ve lokasyonlar arasindaki farklilik istatistiki olarak onemli bulunmustur. 2012–2013 yili Edirne, 2013–2014 yili Edirne ve Kirklareli lokasyonlarinda genotiplerin tane verimi; 281.4–688.3, 349.1–828.0 ve 478.2–993.0 kg/da, bitki boyu; 110.8–156.0, 141.3– 177.5 ve 126.3–171.3 cm, olgunlasma suresi; 29–37, 33–39 ve 36–43 gun, 1000 tane agirligi; 18.7–31.6, 19.6– 38.7 ve 22.7–45.0 g, hektolitre agirligi; 43.9–55.5, 45.7–60.4 ve 44.0–60.7 kg/hl, protein orani; %12.7–15.2, %10.9–14.3 ve %9.0–11.3, tane ic orani %56.1–75.5, 62.5–77.7 ve %61.5–78.4, kavuz orani; %24.5–43.6, %20.0–37.3 ve %21.6–38.2 ve 2.2 mm elek ustu %25.1–81.9, %17.3–93.7 ve %28.3–95.5 arasinda degisim gostermistir. Tane verimi yonunden lokasyon ortalamalarina gore 734.8 kg/da ile 10, 728.1 kg/da ile 7 ve 695.6 kg/da ile 15 nolu genotipler en yuksek tane verimine ulasmistir. Standart cesitlerden 690.2 kg/da ile Kirklar ve 686.3 kg/da ile Kahraman en yuksek tane verimine ulasirken, 372.1 kg/da ile Y-330 ve 397.0 kg/da ile Checota cesitleri ise en dusuk tane verimine ulasmistir. Incelenen ozellikler yonunden one cikan kisa boylu ve yatmaya dayanikli 15 nolu hat, 2014 yilinda tescile verilmistir.
