David: My understanding, which may be based in complete fable, is that Hippeastrelia is a primary cross between a Hippeastrum hybrid and Sprekelia formosissima. At this point, I would assume the red is dominant being the only color for Sprekelia and the dominant color for Hippeastrum. With that in mind, I would guess that a primary cross using a white or yellow Hippeastrum would be the only way to have a chance at diluting red to a pinkish hue??? Any successive generations, I would guess would dilute the phenotypic characteristics offered by Sprekelia if backcrossed to Hippeastrum, or reintroduce the dominance of red if backcrossed to Sprekelia. I suppose your intention would be to keep backcrossing to Hippeastrum, but selecting for outliers that most resemble Sprekelia? I would assume, then, that each generation would be less and less likely to show the phenotypic traits of Sprekelia, which would require the need to observe larger populations for outliers.
