Assessment of Some Agronomical Characteristics in Bread Wheat Breeding Programs of Central Anatolia Region


1 Tarla Bitkileri Merkez Araştırma Enstitüsü Müdürlüğü, ANKARA - The purpose of studies in bread wheat breeding in Central Anatolia Region is to contribute economy of farmer and country by breeding new varieties with high grain yield and quality, resistant to disease especially the yellow rust, cold-and drought-resistant. For this purpose, 20 lines selected from advanced breeding lines and 5 standard varieties were grown in İkizce, Ulaş, Altınova, Gözlü, Malya. Samples were investigated in terms of grain yield, thousand kernel weight, flour yield, protein content, zeleny sedimentation value and yellow rust disease. According to average grain yield of 5 locations, 11 lines had above average yield of trial, 16 lines had above average yield of standard varieties, too. Depending on the changed locations high grain yield was obtained in İkizce, while the lowest yield was obtained in Altınova location. According to the result; lines with 6, 25, 21 numbers and Bezostaja-1 standard variety have been the most stable genotypes at grain yield. In terms of grain yield 12, 16, 19, 17, 6, 14, 10 and 20 numbered lines had the highest values. According to quality characteristics (thousand kernel weight, flour yield, grain protein content, zeleny sedimentation value) 2, 12, 15 and 17 numbered lines came to the fore. With regards to grain yield, quality characteristics and yellow rust resistance, 12 and 17 lines were found promising.
