Hybrid of tomato more diversity

[Adrian]

If i am understand i must just  exchanged the anthers of two flowers of differents varietys, glide the anthers on the stylet and shake them.

[Adrian]

Third cross: canestrino x san marzano 2.
I have shake the flower after to have glide the anther.

[Adrian]

This plant is a solanum pimpinellifolium? I have may a candidat for the resistance at the blight!

[Adrian]

Cross after 24 hours
The female anthers are dry but the pollen is good?

[Steph S]

If the anther cone is dry then it has shed all its pollen.
I don't use this method but with every cross, the next step is to wait and see if the fruit begins to swell.  If it does, then you know the cross was successful.   Don't forget to label your crossed fruit, or you won't be able to find it.

[Adrian]

I put a scotch piece on the pedoncle.
I have thinked the anther cone may protected the pollen of the sunshine ray.I have did the cross the mid and morning day but i think i can have more luck if the cross is did  the evening.
With this method i think if shake the anther after have did the cross is not sufficient the wind can help to have a sucess.
The anther cone is less voluminous and he is retracted on the stylet.

Whether or not a stigma is exserted depends on the length of the style, relative to the length of the anthers. They might be influenced by different genes.

In preliminary measurements of exsertion and flower structure, I'm finding a strong correlation between wide petals, and strong exsertion.

[Adrian]

Your right! Canestrino di lucca are more large petals than the others varietys and he has an exersted moderetly stylet!
The diameter of the stylet is more tall!
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.

[Adrian]

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 shake the flower sometimes.

[Adrian]

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.

[Adrian]

The fecondation is good?
I have unfortunately broke the stylet when i have try to change the anther

[Steph S]

Wait a day or two and you'll see if it's growing or not.

[Adrian]

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.

[Adrian]

Two days later he don't look avorted
If it good its a cross between canestrino di lucca and horned andean

Yarn in different colors is ideal for marking the young flowers for your cross pollination
