Micro dwarf x Indeterminate cross ideas.

Update: 3/19/25


Joro F3-2 BC1 has finally germinated. The root size is as long as the indeterminate Rosella parent plant, which may be an indicator that the backcross is successful. I will check to see if there is any nyctinasty to confirm if it is the case once I plant it tomorrow. Statistically speaking, this generation should be 50% homozygous for Rosella and 50% heterozygous for both parents. This is much different from the F3 parent micro it descended from, which only was 37.5% homozygous for Rosella, 37.5% homozygous for Jochalos, and 25% heterozygous for both parents.

Update 4/1/25 Joro BC1:


It's been about 12 days since I planted Joro BC1. However, I am unsure whether to update because this seedling expressed no nyctinasty after planting. It also isn't as large as the original F1 cross either despite the fact that it should have more genetics from the large indeterminate parent. So far, this plant has not displayed split branching from the either, and the leaves seem slightly rugose. I need to grow it further to see if the cross failed yet again. Luckily I crossed 2 fruits a few weeks back, so I have more insurance in case this one does not go well.

For the F2 segregation project, I found something interesting things. All the indeterminate F2s that I have grown, including the non-dwarf indeterminate, have axillary shoots that flower after 4 leaves have grown.

In another news, I have encountered an early tomato variety called "Scotia" in a discussion server. It's a normal leaf, super early determinate that is grown in Canada. And the flowering habit seems very similar to micro-dwarfs. It seems to grow 8-9 leaves before terminating immediately to 2 flower trusses.

IDK if Scotia is any earlier than the usual early red tomatoes. My friend has grown this one from time to time on her farm. They are vigorous bushes with fruit about the size of apples. About 3 ft tall under field conditions.
