The lines were cultivated in Italy, in two locations, over two growing seasons, and evaluated for several agronomical, morphological and qualitative traits. Analyses were conducted using the most common univariate approach on individual plant traits coupled with a correspondance multivariate approach. ANOVA showed a clear trend from old to new varieties, leading towards earliness, plant height reduction and denser spikes with smaller seeds. The average protein content gradually decreased over time; however this trend did not affect bread-making quality, because it was counterbScientific reports8574https://www.ebi.ac.uk/biostudies/studies/S-EPMC4339800biostudies-literatureDiversity trends in bread wheat in Italy during the 20th century assessed by traditional and multivariate approaches.PMC4339800Costa CNegri SPerenzin MOrmoli LVaccino PfalseDiversity trends in bread wheat in Italy during the 20th century assessed by traditional and multivariate approaches.A collection of 157 Triticum aestivum accessions, representative of wheat breeding in Italy during the 20(th) century, was assembled to describe the evolutionary trends of cultivated varieties throughout this period.
