Thanks for the quick link, unfortunately I was expecting another color variant of the red pear and yellow pear types, so not quite the same. However it just backs up my idea of breeding in some new colors into those lines.

I'm sure I saw a cherry-size pink pear somewhere too, I just couldn't find it again real quick. I wonder what would be involved in miniaturizing the one from TFest?

Just what Alan needed- another project.  |

Thanks flowerpower. I have some red fig tomato too so that is a likely candidate..maybe crosses to Thai pink egg or pinkping pong.

I would more likely cross yellow pear with a pink cherry of some sort to get that Pink Pear cross, though it wouldn't be hard to make the cross with the other large pink pear, I have a feeling selecting for size and shape might be a little aquard.

Does Yellow Pear have a clear epidermis or a yellow epidermis?
If yellow rather than clear, then you'll get a red pear when crossing Yellow Pear with a pink cherry.
In order to get a pink pear you'll have to do your crossing with only clear epidermis varieties.
BTW, I have a clear pink, elongated cherry that wants to be a pear but still looks more like a grape shape at this time ... Una Hartsock. If you have a clear epidermis pear shaped cherry or saladette to cross with Una Hartsock, you might get a clear pink pear in the F1.

I wonder if it's worthwhile to make two crosses and then cross them together so you have the recessive trait you want in both parent lines, so you'd be more likely to get the recessive trait to show up in your hybrid you want to dehybridize? yes, this is sometimes refered to as backcrossing. |

I had plans once upon a time of crossing yellow or red pear to some other colors, particularly Cheroke Purple or Black cherry and selecting for a black pear which would inebitably be called "cherokee trail of tears." It might just get done this summer now that I'm ready about your new ideas, time will tell. -Alan You should try using "Yellow Submarine" as a parent instead of Yellow Pear. YS is a PL yellow pear with what seems to be better flavor and texture. I kinda suck at getting seeds out but I saved PLENTY for this very reason - to share. Pear shape comes from two recessive genes so it takes more numbers to find them when crossed with rounds. This is a case were backcrossing could up those chances. |

Thanks K. I thought back crossing was making a hybrid then crossing it back with one of the parents. Glad you stopped in!

Yeah, I figured the pear shape was pretty recesive given the limited gene pool of pear type tomatoes, though I hadn't set down and taken the time with yellow pear to think about the color of the epidermis which indeed to my remembrance yellow in color, I will have to do some searching. I'm presuming red pear is a red epidermis tomato, so that's out, this will take some time and research to make happen, though searching for recessives could be fun and i've got plenty of room to grow them out, so that's fine. I'll do some thinking and see what I can find out.

Yellow Pear is yellow skinned
Yellow Submarine is yellow skinned.
There IS a smaller pink pear. I have seen it before. Totally Tomatoes had them listed once but when I got seeds from them they ended up being red (yellow skinned).
From what I had heard about pink pear was that many didnt like it because it split so easily. That could be why it is not around.

I'm going to see if I can't track down that pink pear, if nothing else just out of curiosity. If not then I do have a pink grape tomato with a clear epidermis that I could use for some breeding work and see what I can do. All I can do is try and see what I get out of it, but I think given a few years and some back crossing I can get something decent.
