Scars and cracking
« on: 2021-09-26, 03:01:39 PM »

The tomatoes above are F2 Galahad tomatoes. They have long brown scars. What causes these scars?
Most F2 plants show no scars.

Heavy rains / rapid changes in moisture can result in these issues.

Some varieties tend to crack more than others, the cracking on your F2 plant could genetic or the spot it was planted in received more water than other plants.

In papers I read the most scar resistant genes are recessive. And scar resistance is modified by 2 or 3 main genes.

If the F1 do not have scars, most of the F2 does not have scars and i take F3 seeds from a plant with scars. Can I still get F3 tomatoes resistant to scars?
