¹ Abbreviations: R = resistant; MR = moderately resistant; MS = moderately susceptible; S = susceptible; VS = very susceptible.
² Ratings are based on very limited data and should be considered tentative. XL6 ratings are based on higher than recommended nitrogen rates. Few disease problems are expected if XL6 is grown using the low N rates suggested by RiceTec.
