ÖzBu araştırma; 2007-2009 yılları arasında Trakya Tarımsal Araştırma Enstitüsü deneme alanında, Tesadüf Bloklarında Bölünmüş Parseller Deneme Desenine göre dört tekrarlamalı olarak yürütülmüştür. Denemede; ana parsel olarak çeşitler (Flamura-85, Gelibolu, Kate A-1 ve Guadalupe), alt parsel olarak 4 farklı tohum irilikleri (2.8 mm üstü, 2.8-2.5 mm arası, 2.5-2.2 mm arası ve 2.2-2.0 mm arası) ele alınmıştır. Araştırma; farklı 1000 tane ağırlıklarına sahip dört ekmeklik buğday çeşidinde 4 farklı tohum iriliğinin tane verimi, verim öğeleri ve bazı kalite değerleri üzerine etkisini belirlemek amacıyla yapılmıştır. Yapılan varyans analiz sonucunda tane verimi, metrekarede başak sayısı, başakta tane sayısı, bin tane ağırlığı ve hektolitre ağırlığı yönünden çeşitler arasındaki farklılık istatistiki olarak önemli bulunmuştur. Tohum iriliği, her iki yılda da tane verimi, 1000 tane ağırlığı ve hektolitre ağırlığını etkilerken, metrekarede başak sayısını ve başakta tane sayısını etkilememiştir. Tohum iriliği artıkça çeşitlerin tane verimi artmıştır. En yüksek tane verimi 2.8 mm üstü tohum iriliğinden alınırken, en düşük tane verimi ise 2.0-2.2 mm arası tohum iriliğinden alınmıştır. 1000 tane ağırlığı yüksek olan çeşitlerde tohum iriliği artıkça tane verimindeki artış oranının daha fazla olduğu saptanmıştır. Araştırma sonucunda; bölgede Gelibolu ve Flamura-85 çeşitlerinde 2.5 mm üstü, Kate A-1 çeşidinde 2.2 mm üstü ve Guadalupe çeşidinde ise 2.0 mm elek üstü tohumluklar kullanılmalıdır. Effects of Different Seed Sizes on Grain Yield, Yield Components and Quality of Some Bread Wheat (T. aestivum L.) Varieties AbstractThis study was conducted in the experimental field of Trakya Agricultural Research Institute in a randomized split blocks design with four replications in two years (2007-2008 and 2008-2009 growing seasons). The experiment was set up cultivars (Flamura-85, Gelibolu, Kate A-1 ve Guadalupe) as main plot and four different seed size (above 2.8 mm, among 2.8-2.5 mm, among 2.5-2.2 mm and among 2.2-2.0 mm) as subplot. The objective of the study was to determine the effects of four different seed sizes on grain yield, yield components and quality in bread wheat cultivars which have four different kernel weight. According to the results obtained from analyses, differences between cultivars in terms of grain yield, number of spike per square meter, number of kernel per spike, thousand kernel weight, test weight and protein rate were found statistically significant. While grain yield, thousand kernel weight and test weight were affected by the seed size, number of spike per square meter and number of kernel per spike weren't affected by the seed size in both years. The grain yields of cultivars went up with increasing seed size. While the highest yield was obtained with 2.8 mm and above seed size, between 2.0-2.2 mm seed size gave the lowest yield. Increasing seed size in cultivars having high kernel weight caused greater yield increase more than in cultivars with low kernel weight. Based on the results of the study, abo...

yıllarında Edirne'de yürütülmüştür. Deneme 22 çeşit ile tesadüf blokları deneme desenine göre 4 tekrarlamalı olarak kurulmuştur. Tane verimi, bayrak yaprak alanı, bitki örtüsü sıcaklığı, bayrak yaprak klorofil miktarı, yaprak su tutma kapasitesi, kuru madde oranı, bitki boyu, başaklanma ve olgunlaşma gün sayıları gibi özellikler incelenmiştir. AbstractThis study was carried out to determine grain yield, some agricultural and physiological characteristics of the some bread wheat varieties in 2009-2010 and 2010-2011 growing seasons in Edirne. Experiment was set up with 22 cultivars employing completely randomized blocks design with four replications. The characteritics such as grain yield, flag leaf area, canopy temperature, chlorophyll content of flag leaf, water content and dry matter of flag leaf, plant height, days to heading and maturating were scored.Except grain yield all other characteristics were statistically significant. The two year average grain yield of all varieties was 721.8 kg/da. The highest grain yield (762.3 kg/da) was obtained from Trakya BVD7 . Tina variety gave the widest flag leaf area (32.96 cm 2 ), while the lowest leaf area was measured in Kate A-1 variety with 18.54 cm 2 . Measurements of canopy temperature and chlorophyll content in flag leaf were performed at heading stage. Canopy temperature varied between 22.66 o C and 25.75 o C, the highest canopy temperature was measured for Tina and, the lowest was for Milena cultivar. The highest and lowest chlorophyll contents (53.41 and 46.89) were measured in Tekirdağ and Golia cultivars respectively. Bereket and Tekirdağ varieties gave the highest leaf water content and dry matter values, respectively. Although canopy temperature positively correlated with flag leaf area, it turned out to be negative with plant height (r=-0,459) and leaf water content r=-0,355). Coeffiicinet of correlation between plant height vs.chlorophyll content and leaf water content were positive but insignificant. Trakya BVD7, and Nina were prominent genotypes with their highest yielding capacities based on the result of the study. Relationship between grain yield versus physiological traits should be further carried out under drought conditions.

Araştırma 2008Araştırma -2009 Investigation of Grain Yield and Agronomic Characters of the Some Barley (Hordeum vulgare L.) Genotypes in Trace Region AbstractThis research was carried out to determination yield and some agronomic traits of the cultivar and advanced lines developed by breeding works. Experiment was set up in 2008-2009 growing season in Edirne and Tekirdağ locations with 25 genotypes in randomized completely blocks design with four replications. Grain yield, plant height, lodging resistance, date of heading and maturity, resistance to powdery mildew and net blotch, 1000 kernel weights, test weight and protein ratio and relationship among these characters were investigated. The results showed that there were significant difference among the genotypes than grain yield and some other investigated characters. Mean grain yield of the genotypes was 524.1 kg/da, and the highest grain yield with 619.5 kg/da was determined in Martı cultivar. Mean yield was 488.3 kg/da and 560.0 kg/da in Edirne and Tekirdağ locations respectively. Plant height ranged between 89.5 cm and 108.5 cm. In Trakya region mainly widely disease is net blotch (Drechslera teres f. teres) and it was determined that almost all genotypes were medium susceptible to net blotch. The highest 1000 kernel wight was determined in TEA1619-20 and test weight in TEA1619-17 lines. According to protein ratio there was significant differences among genotypes and highest protein was determined with 12.5% in Lord cultivar. The highest grain yield was determined in genotypes with early maturating and tall plant height. Identifying positive relationship between lodging resistance and plant height (r=0.871**) it was showed that this character can be used for lodging resistance. Martı, Hasat, TEA1619-17 and TEA1619-20 had most prominent genotypes based on yield and some other investigated characters.
