Hi
Do you know what is the genetic behind indeterminate dwarfs like in the dwarf hemisphere project ? Is this just a d+Sp background instead of the d+sp determinate dwarfs like MicroTom ? Thanks |

MicroTom has at least two dwarfing loci, in addition to the self-pruning trait. I'm not remembering what the exact gene names are, however. I and a few others refer to plants like this as being "micros" instead of "dwarfs". Some discussion over in this thread.

The genes I was trying to think of are: "d" (for "dwarf") and "sd" (for "sun-dwarf"). "Sun-dwarf" refers to a trait that only shows dwarfing when there is a lot of light available.
Another couple micro varieties that are easy enough to get ahold of are "Tiny Tim" and "Red Robin".
