Evaluation of Grain Protein Content in Triticum turgidum ssp. turgidum Landraces from Southwest China

Wei Li, Yu-Ming Wei, Ze-Hong Yan and You-Liang Zheng    

Abstract: The grain protein contents of 84 Triticum turgidum ssp. turgidum landraces from Southwest China, including Sichuan, Shanxi, Gansu, Henan and Jiangsu provinces, were investigated. Higher variability for protein contents was observed. Based on analysis of variance (ANOVA), it was found that the genotype and year had significantly effects on the protein content. The negative significant correlation between grain protein content and 1000-grains weight was detected. Significant differences of the protein contents within the groups of landraces from Gansu, Sichuan and Henan were observed, whereas no significant differences within the group of landraces from Shanxi. However, there was no significant difference between the groups of landraces from Gansu, Sichuan, Henan and Shanxi. Cluster analysis indicated that the landraces from different province could not be distinguished. According to protein content, the landraces could be divided into 6 groups. These results could be useful for the genetic resources conservation and the improvement of wheat quality.
