This might be slightly off topic, but has anyone focused on using S. peruvianum to introduce higher sugar content or unique flavor profiles to the domesticated tomato? S peruvianum is quite far removed genetically from domestic tomatoes. The manual crosses that I attempted were not successful. I keep planting the peruvianum/corneliomuleri species complex nearby to the lycopersicon complex, and habrochaites/pennellii populations. Eventually some natural hybrids might show up. |

This might be slightly off topic, but has anyone focused on using S. peruvianum to introduce higher sugar content or unique flavor profiles to the domesticated tomato? It seems most of the wild species are used mainly for disease resistance, grafting, or technical science mumbo jumbo LOL Not exactly. But.. i received LA4454. I'm not sure if that is the one i requested originally as they were low on stock on a few and replaced them with others. LA4454 is a high sucrose line. It does not say where it comes from, but some of the others say this: " High fruit sucrose from S. chmielewskii". Not peruvianum, but still another wild species. LA4454 is also odd in that it says it also has the j gene, meaning "jointless". Jointless is a rare trait that is from cheesmaniae and is often used as a genetic marker for following cheesmaniae breeding lines. I wonder if LA4454 also has cheesmaniae genetics... Either way it is a high sucrose line. while sugar does not always equate with flavor, it might be important. Sadly i'm having terrible luck with a lot of my tomato seedlings this year. I think my germinated LA4454 seedlings died along with BC1 and many others! grr. trying to just plant what i can. |

I spent yesterday evening watching pollen grains start to grow tubes and then pop, spilling their guts out onto the slide. I'd adjust the formula, try again, and about 9 minutes later, "Pop!" out came the guts. It was the most fun I've had in a long time. Thinking on it this morning, I think I made a mistake with the amount of sucrose in the solution. Hopefully I have a flower or two to work with again tonight. keen101 (Biolumo / Andrew B.), I imagine I'm going to have a fair number of posts on this subject, as I work my way through various species of beans and different techniques. It's pretty far from the main topic of this thread, but since we're both trying very similar overall techniques it's nice having the discussion in one place. Would you like me to create a new thread called "Advanced pollination techniques" or something, or are you fine with me continuing to post here? Maybe it couldn't hurt copying some of these posts maybe from page 5 onward into a new thread like that. Joseph Lofthouse, i don't know if a mod can copy posts into a new thread like that or only move them. I'm Fine with leaving the originals here, but copies would be nice. Fun topic. Now i want to try all this again! |

I took two cuttings of my F2 potato leaved pennellii hybrid. Trying to root them for winter growing. They Root better than peruvianum and habrochiates tough woody stems, but not quite as easily as domestic. Somewhere in between. I probably should have gotten some other cuttings, but i got distracted. The Interesting thing is both my cuttings May have set fruit on them. That would be neat, could either be bee pollinations, or since it is late in the season it could be that 4% selfing that pennellii is reported to have when the plant detects no pollinations have occurred. Hopefully i can save the fruits. One has them rather low and close to the cut end. The other is taller and has them up high. Getting ready to finish up my grow cube. If i had to do it over a cheap pot grow cube from Amazon would probably be cheaper and the way to go. Maybe an idea for William since he does not have a winter grow idea yet. Ooh.. Joseph Lofthouse mostly, i know you've said that you've seen a lot of variation in vigor in your pennellii hybrids. I wonder how many vary in ease of rooting cuttings? That might be a domestic trait worth selecting for. |
