Yağmura Dayalı İklim Koşullarında Tane Verimi ve Bazı Kalite Özellikleri İçin Arpa (Hordeum vulgare L.) Hatlarının Seçimi

Abstract

This research was
 conducted to select barley lines with high grain yield and quality traits,
 adaptable to dryland environments by evaluating grain yield and quality traits
 of some barley lines in Konya Province of Turkey. In this study, 19 advanced
 lines which were improved in barley breeding program in Bahri Dagdas
 International Agricultural Research Institute (BDIARI) and 5 standard varieties
 (Karatay 94, Tarm 92, Ince 04, Tokak 157/37 and Larende) were used. The trials
 were setup in randomized complete block design with 3 replicates during growing
 season in 2011-12 and 2012-13. During the study, the grain yield (GY), thousand
 kernel weight (TKW), kernel size (KS), test weight (TW), crude protein content
 (CP), and crude fiber content (CF) of barley lines were determined. The
 differences among the genotypes were found statistically significant with
 respect to the studied traits. According to the results obtained for both
 years, the GYs of barley lines ranged between 3.18 and 4.33 t ha-1.
 The highest GY was obtained from advanced line 17. Karatay 94 had the highest
 yield with 4.05 t ha-1 among control cultivars. The values ranged in
 genotypes between 33.7-43.2 g in TKWs, 57.2-86.6 % in KSs, 58.5-65.0 kg hl-1
 in TWs, 10.91-12.65 % in CP, and 6.11-7.36 % in CF. To conclude 4, 14 and 17
 numbered lines were promising with higher GYs and better-quality properties in
 the rainfed conditions. Therefore, these lines were selected as new cultivar
 candidates for use by dry farming farmers and to use as parent in the development
 of new varieties by barley breeders.
