The phenotype of MRDD in the RILs and parental lines. a Frequency distribution of DSI (%) in the RIL population in two field trials (2013-A and 2013-B). The number of individuals in each phenotypic class is indicated on the y-axis and the phenotypic score classes on the x-axis. b Individual plants from parental lines “80007” and “80044” after artificial inoculation. c The DSI of the parental lines in Taian in 2017, Hainan in 2018 and Taian in 2019 (**P < 0.01; two-tailed Student’s t-test)
