This study examined grain yield and grain quality (protein content, 1000 kernel weight, SDS sedimentation) of 100 wheat plant materials including 4 varieties (Gerek, Aytin, Kutluk and Kirac), 6 sister line mixtures (with each mixture consisting of 15 sister lines per diallel cross) and 90 F7 sister lines (6 crosses x 15 sister lines). In total, 100 different plant materials were used in a 10 x 10 lattice design. Plant material was sown during the 2006- 2007 growing season in two locations in Turkey (Eskisehir and Mahmudiye) with three replications per location. Analysis of variance of the combined locations found significant differences (p≤0.01) between locations and among genotypes for all 4 parameters examined. Grain yield varied significantly (p≤0.01) by block [replication] in Eskisehir and by variety in both Eskisehir and Mahmudiye. Mean grain yields at Eskisehir, Mahmudiye and the combined locations were higher for sister-line mixtures when compared to sister lines and varieties. Mean grain yields of the combined locations varied between 5125 kg ha-1 (GRK/AYT) and 2764 kg ha-1 (GRK/KRC-9). Significant differences (p≤0.05) in SDS sedimentation of plant materials were found at both Eskisehir and Mahmudiye, whereas significant differences (p≤0.05) in 1000 kernel weight and protein composition were found at Eskisehir only. In high-variety vigor, significant difference (p≤0.05) was detected for protein content at AYT/KRC (-6.8) among the sister-line mixtures in the combined locations. These results suggest that a good mixture of sister lines may result in higher grain yields. Further studies are required that look at grain yields among a greater number of sister lines.

The spring triticale cultivars Aysehanim and Mehmetbey (X Triticosecale Wittm.) were developed by Agricultural Research Station of The Eastern Mediterranean Transition Zone and they had been registered by Variety Registration and Seed Certification Center in Turkey. In this experiment, some characteristics of two new varieties were studied. The experiments were conducted at four locations of the Eastern Mediterranean Transition Zone in Turkey with three check triticale cultivars (Egeyildizi, Taceddinbey and Focus) under rain-fed conditions during the 2009 – 2010 and 2010 – 2011 growing seasons. The locations were Kahramanmaras, Adana and Hatay provinces and Ceyhan town. The genotypes were tested for agronomic, quality and botanical characteristics. Also, resistance of some cereal disease and lodging of the genotypes were determined. Aysehanim and Mehmetbey cv. had good adaptation and agronomic performance in the Eastern Mediterranean Transition Zone. The grain yields of Aysehanim and Mehmetbey cv. were 6459 and 6387 kg ha-1, respectively, and these values were significantly higher than the grain yields of Egeyildizi and Focus check cultivars, 5916 and 4919 kg ha-1, respectively. The cultivars had acceptable quality traits compared to the check cultivars. While their hectolitre weights and 1000 kernel weights were higher than the averages of check cultivars, protein content was not higher than those of the checks. Aysehanim and Mehmetbey cv. had good resistance for rust disease and lodging.
