The impact of the crown rot and common root rot interaction in two bread wheat varieties across three field trials

Three crown rot x common root rot yield loss trials detailing the impact of Fusarium pseudograminearum and/or Bipolaris sorokiniana on disease severity, yield, physiology and agronomic traits. One data file “CR x CRR (unpublished)_disease data.csv” contains plant-level disease measurements collected at flowering and post-flowering stages. Another data file “CR x CRR (unpublished)_incrop data.csv” contains plot-level agronomic and yield data collected during the growing season and at harvest. The three yield-loss field trials were conducted in 2020, 2022, and 2023. Trials included inoculation treatments: plus, and minus Fusarium pseudograminearum and/or Bipolaris sorokiniana. Two bread wheat genotypes tested in each trial. In-crop data includes emergence counts, flowering time, whitehead incidence, yield, screenings, thousand-grain weight (TGW). Disease data includes lesion measurements on subcrown internode (SCI), main stem, and primary stems; plant height; tiller and head counts; DNA quantification of pathogens.

本数据集包含三项冠腐病×普通根腐病产量损失试验，用于详细阐明伪禾谷镰孢菌（Fusarium pseudograminearum）和/或禾谷根腐离蠕孢（Bipolaris sorokiniana）对病害严重度、产量、生理性状及农艺性状的影响。其中，数据文件"CR x CRR (未发表)_病害数据.csv"包含开花期及花后阶段采集的植株级病害测定数据；另一数据文件"CR x CRR (未发表)_生育期田间数据.csv"包含作物生长季及收获期采集的地块级农艺与产量数据。该三项产量损失田间试验分别于2020年、2022年及2023年开展，试验设置接种与不接种伪禾谷镰孢菌（Fusarium pseudograminearum）和/或禾谷根腐离蠕孢（Bipolaris sorokiniana）的处理组，每项试验均测试了2个面包小麦基因型。生育期田间数据涵盖出苗数、开花期、白穗发病率、产量、筛下物率、千粒重（TGW）；病害数据包含冠下节间（SCI）、主茎及一级茎的病斑测量数据，株高、分蘖数与穗数，以及病原菌DNA定量检测结果。
