Potatoleaf how??

[dld]

Is there a way of finding out how PL's came about? What bred with the RL to get the PL's?

rich, here's a brief explanation. For a far more detailed discussion see the sticky in the tomato breeding subforum written by Keith Mueller.

if the F1 generation cross is PLxPL then the resulting plants wil be all PL since PL is a recessive gene and will give nothing but PL plants.

if the F1 generation cross is RLxPL then the resulting plants wil be RLPL and show the regular leaf gene since RL is dominant.

if the F1 generation cross is RLxPL then the resulting plants wil be RLRL, RLPL, RLPL,and PLPL. Three plants will be RL in appearance and 1 plant will br PL in appearance

I was thinking DLD's question is more along the lines of where did the smooth-edged, potato leaf looking shape come from originally. Like whether it's always been lurking as recessive genetics since man first domesticated the tomato. Or whether it was introduced from another wild species somewhere along the line as man or nature crossed other genetics into the already domesticated tomato.

I would ask the same question regarding rugose foliage and shortened internodes, but that might better be asked in another forum than the PL forum.
