Özet

Biodiversity is very important for plant breeding programs since they should be supplemented and enriched with broad-based genetic materials. Grasses and legumes extensively grow in rangeland vegetation in Turkey. Crested wheatgrass is palatable perennial grass and provides good-quality herbage. It can be grown on rangelands and marginal areas for hay production under semi-arid conditions. In this study, first, the genotypes of crested wheatgrass were screened and tested for morphological and phenological characteristics on a nursery plot. Then, one advanced population with 18 lines, G-465, was identified as a promising variety candidate, and regional trials were set up with the advanced population and the country population during the years from 2007 to 2010 in Yenimahalle and Golbast towns in Ankara province. The objective of these trials was to determine the adaptation ability, and yield potential of the advanced population under semiarid conditions. All the data was statistically analyzed and two genotypes features were compared by the F test. The morphological and agronomical features were examined comprising the height and diameter of the main stem, inter node distance length and node numbers in the main stem, length and width of flag leaf, and yields of green herbage and hay. The green herbage and hay yields of the advanced population were 4688.0 and 1172.0 kg ha in Golbast and 6245.0 and 1884.0 kg ha (1) in Yenimahalle, respectively. The morphological cha-racters, i.e., the main stem length, main stem diameter, length of internode, node numbers in the main steam, flag leaf length and flag leaf width of the advanced population and the country population were 53.6 cm, 56.9 cm; 2.0 mm,1.8 mm; 11.6 cm, 11.0 cm; 3.8, 4.3; 9.5 cm, 9.0 cm; 5.2 mm, 5.2 mm, respectively for Golba i and 52.5 cm, 52.2 cm; 1.9 mm, 1.9 mm; 12.2 cm, 11.7 cm; 3.5, 3.3; 11.2 cm, 11.8 cm; 6.5 mm, 6.9 mm, respectively for Yenimahalle. Correlation analysis was undertaken, and hay yield was found to have a strong relationship with the main stem length, length of internode, flag leaf length, flag leaf width and green herbage yield. The results of the trials indicated that the advanced population was promising for yield potential under semiarid conditions.
