İleri Kademe Arpa (Hordeum vulgare L.) Genotiplerinin Verim ve Bazı Fizyolojik Özelliklerinin Eskişehir Koşullarında Belirlenmesi

Abstract

In this study, it was aimed to develop higher yielding winter barley varieties with lodging resistance, medium early maturing and higher grain quality for Central Anatolia and Transitional Zone regions in both irrigated and rainfed conditions. In the trial, 11 lines from Transitional Zone Agriculture Research Institute and varieties such as İnce-04, Larende, Tarm-92, Ünver, Özdemir-05, Erginel-90 and Keser were used as standards. Trials were set up as Randomized Complete Block Design with 4 replications in 2014-2015 growing season in Eskisehir Center, Sultanönü (rainfed) and Soil-Water (irrigated) locations. According to the results of this research, the differences among genotypes were found significant (P<0.01) for all traits in both environments. Lines 9, 10, 11 for grain yield (GY), Erginel-90 for plant height, lines 1, 10, 11 and Larende for 1000 kernel weight in irrigated conditions, lines 5, 8 and 10 in rainfed conditions were prominent. Lines 1, 3, 9 were found as early heading genotypes. Negative correlation was found significant between grain yield and lodging score, days to heading parameters. Whereas, positive correlation was found between 1000 kernel weight and grain yield. When all the parameters were evaluated together, it is determined that the lines 10 and 11 were prominent.

Investigating of Some Agricultural and Quality Traits of Advanced Barley (Hordeum vulgare L.) Lines

“…In this study, all genotypes except Erginel-90, which is a six-row control variety, were above the 40 g TGW limit, one of the malting quality criteria. The average TGW value found in this study was consistent with the values found by Sönmez and Yüksel (2019). The TGW results obtained in this study were found to be consistent with some studies (Sirat and Sezer, 2009;Aydoğan et al, 2011;İmamoğlu et 2016).…”

“…In this study, it is seen that line18 is the closest line to our breeding objectives with 101.4 cm PH. In another study conducted by Sönmez and Yüksel (2019) in Eskişehir, the average PH was found to be 84.2 cm in dry conditions as compatible with this research. Öztürk et al (2016) reported that PH is a significant element in terms of resistance to the lodging of barley and that short or medium-height varieties with a PH of 85-95 cm are preferred.…”

“…It is thought that the average of 119.5 days obtained in this study was due to the drought in April caused stress on the plant and shortened the DTH period (Table 1). In a study conducted by Sönmez and Yüksel (2019) in Eskişehir, the average DTH was 136.6 days, while Kara et al (2019) was found 133.4 days in another study in Konya. The reason for the statistical difference about DTH between the related locations is that the Hamidiye site has an altitude higher than the Eskişehir site and the average temperature values are lower than the Eskişehir.…”

“…Due to the development of animal husbandry and the fact that barley is earlier maturing than wheat, barley production is increasing as the first crop in areas where two crops can be grown per year (Öztürk et al, 2007). Lodging is one of the factors that cause crucial yield and quality loss in barley during the years when rainfall is high and these losses can be prevented by using durable cultivars (Sönmez and Yüksel, 2019). Plump grain size and homogeneity are some of the traits desired by the malt industry and are taken into account in determining the barley price (Sönmez et al, 2020).…”
