A breeder to be admired for sure but not every cross involves a PL parent, in fact I would say the majority don't.
for my part, using the RL Heart as the mother, rather than the obvious and standard wisdom of using the PL parent worked out really, really well for me. Rookie mistake? some would and have said so ![]() bumblebees have made many of the greatest tomato crosses ever grown. Making the cross itself is the easy part. Selecting and then stabilizing the final OP tomato worth growing takes years of careful work and record keeping. KarenO Last edited by KarenO; December 12, 2017 at 12:59 PM. |

As to your comment that not every cross involves a PL, you would say the majority don't. In knowing quite a few professional and not so much even amateur breeders then begs the question of WHO the majority is. Which I cannot even begin to answer considering the fact that that means going WAY back in tomato history to deliberate breeding as well as great accidental crosses that took place and we can blame the pollinators for that as well as seed mutations and somatic mutations. ![]() Carolyn

Just strictly by numbers and due to the dominance of the trait there are more RL tomatoes in the world than PL. this is the basis of my suggestion that the majority of intentional crosses don't necessarily involve a PL parent.

Using a PL mother is a great trick for beginners, because it allows you to see right away whether your cross took if you have any uncertainty about it.
![]() And there are other reasons for choosing a mother, for sure equally valid. One that Fred H pointed out awhile back is the receptivity or ease of working with a certain mother - not all tomatoes are equally easy to cross to. I have definitely noticed that as well. ![]() Choice of mother is most important, perhaps, where the traits of interest are strongly affected by maternal DNA, due to the influence of mitochondrial and chloroplast DNA on specific traits such as earliness and cold tolerance. It is easier to recover those traits in F2 etc by choosing the right mother. |

Karen & Phila, I planted 11 F1's to ensure I got one that crossed. I'd love to thin them down.
They're producing surprisingly well. (I'm vibrating the blossoms.) There will be at least two of us making selections, so double the F2 seed. Quote:
Carolyn, I wholeheartedly agree! Originally, I had a recessive leaf female parent- the rugose Hardin's Mini was to be the momma. About 40 failed crosses later, I used the RL heart as the female in desperation (it was late August). Nan |

Carolyn, just noting that rugose describes the pleated nature of the leaf form surface and has nothing to do with PL or RL.
