This year is extremly bad for the tomatos. I have rarely see a do blight epidemic. I want did a thing. I will try to create my firsts hybrids of tomatos. Today, i have did 2 cross: Horned Andean x canestrino di lucca Canestrino di lucca x San marzano 2 Canestrino di lucca has the advantage to be a little exserted it may interessant for later.
In general many tomatoes form crumpled oversized flowers, like those flowers on beef tomatoes. If you collect seeds from these flowers (and not from the perfect shaped flowers), you increase the chance of finding naturally occurring outcrosses. I started my landrace with only these flower types, thinking I was selecting for flesh types, but instead it turned out that my seedling tomatoes produced many different fruit types and colours over time. I even found Late Blight-tolerant plants this way. Of course, you need many mixed plantings with different tomato varieties. It is also good to use seeds from hobby growers, from seed fairs or from your neighbours. Commercial varieties are often too uniform, form almost only closed flowers and have little genetic diversity. However, it is also possible to use them.

I have try a 4th cross between canestrino di lucca and andean horned this evening with the same method to glide the cone anther of andean on the stylet of canestrino di lucca and shake the flower.As the night is more fresh than the day i think the pollen will be viable more long time.The minimale temperature this night will be at 16°C 61°F.I think it a good temperature for a good fruit set!I think the most dangerous for the viability of the pollen are the sunshine rays
I have take the anther of andean with the petals. I have enroled the petals around the anther cone for protected the pollen of the sunshines rays. I have did my croce yesterday at 21 hours and today at 11hours the petals are dry but the anther is perfect.
I will try a 5th cross between canestrino di lucca and san marzano 2 and i will try to collect pollen and glide an anther of san marzano on the stylet of canestrino. I don't think it sufficient to glide the anther on the stylet.
Second method: i have glide two anthers on the same stylet. I have put an anther of canestrino di lucca and a anther of san marzano for fecondate andean. The diversity of pollens can increassed the fecondation rate.
we have some kind of blight every season, the only question is how resistant the plants will be. no matter what we usually get a decent crop, which is why i don't really get upset any more when i see it start up, it just is. towards the end of the season the plants look like they've been through a war but they still give us fruits.
i hope something fun comes from these! we've had the usual crud show up this season already and it looks like it is going to be pretty bad, but hopefully we'll get some kind of crop. there are a lot of tomatoes on the plants already. we should start seeing some ripening in the next few weeks. no sign yet of tomato worms. always challenges out there...
