Diversity analysis for quality traits in exotic and Syrian genetic resources of wheat


Eleven genetic resources of primitive wheat originated from (Italy, Ethiopia and Syria) belongs to three species (Triticum. dicoccum, Triticum. polonicum and Triticum. carthlicum) were planted in RCBD design with three replicates at Homs research centre, General Commission for Scientific Agriculture Research GCSAR, Syria, during the two growing seasons 2018/2019 and 2019/2020. The objectives of this study were to estimate the potential diversity between studied wheat genotypes in quality by using multivariate (GGE, PCA and Cluster) analysis, and to define the best genotypes to be used in wheat breeding for quality. Studied grain quality traits were: Dry matter%, protein%, wet gluten%, Starch% and hectoliter. Results showed that only PC1 and PC2 were indicators of 77.7% of diversity (mainly 54.7% due to protein, wet gluten and Starch related to PC1). Cluster results revealed that the Syrian and Ethiopian genotypes were clustered together with almost 79% of similarity. GGE results indicated that three Italian genetic resources (1939, 1947 and 1952) were the best in protein% and wet gluten%, While the Italian genotype 1989 followed by the Syrian genotype 1709 were the best in starch%. Hence, the mentioned genotypes will be a proper genetic resources for improving wheat quality.
