First post in here. A few of my heirloom Black Krim seed stock started to produce Roma shaped fruit (and pointed leaves), but same colour and taste. I have never grown Roma and they are behind insect nets. What's going on here?

    It was probably cross pollinated by some adventurous bug that got through your net.

    Oh that’s interesting. I tried growing Black Krim for the first time this year and I got fruits that looked exactly like the one on the left on your picture. Oval/egg shaped and orange-brown. They were pretty bland.

    I assumed there had been a mix-up and I had not been sold Black Krim, but I hadn’t considered that maybe rather than a mix up the seller had suffered some unwanted cross-pollination.

    They were cross pollinated at the seed vendor unless these were from seeds you saved yourself. Cross pollination only affects the next generation of saved seeds, it doesn’t affect the current plants production

  4. So did the plant produce normal black krim fruits to start and then over time they started to be these romas? Or the plant produced the roma shaped fruits from the beginning?

    Someone can correct me if I’m wrong, but I’m pretty sure you’re not going to have different fruit from first generation cross-pollination.

    It’s only the seed of the cross-pollinated fruit that will produce different results

    It’s possible that the seed you have is either from cross-pollinated fruit or F1 hybrid stock.

    This happened here. A big problem planning several types of nearby structures.

    What they said. The fruit from which your roma seeds were harvested had been crossed. Did you buy these seeds, or did you save them yourself?
