Micro dwarf x Indeterminate cross ideas.

[KaguyaCloud]

Very interesting on your observations on vigor and fruit set. I actually have the opposite problem with micros when they are grown in small pots! They almost always become top heavy with the fruits they set and fall off onto their sides a lot. Since they're stems are much shorter and their trusses are more compact, they can support quite a lot of fruit with any breakage. It also helps that the stems are quite thick as well.

In terms of flower morphology, I think the micros I am currently breeding inherited the less delicate pistils from the indeterminate cherry plant. They are much easier to de-masculate than normal micros. However, it seems consistent that their anther cones is about half the length of a normal tomato flower anther cone.

Parthenocarpy is actually quite easy for me to see since my micros should have clear skin, yellow flesh, and green gel. Fruits with viable seeds form a green gel coat around them. All I need to do is hold the fruit over a bright light and see if there's any green.
