  Effects of sister line mixtures on grain yield and some quality parameters in wheat

  Yildirim, Mustafa; Cakmak, Mustafa

  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.
