Carolyn -
My notes say "hard - doesn't soften until damaged". So apparently it does have the ability to soften, but that ability isn't triggered until the fruit is damaged. Maybe it responds to ethylene but doesn't normally produce any? The variety is PI 306811. I'm not sure if it will set fruit this year. This species shows self-incompatibility and I only started two plants. Fred |

Large showy flowers are typical of plants that require insect pollination. Smaller and less showy flowers are typical of plants that are self pollinated by wind or other means.
Domestic tomato is self pollinated and has relatively small flowers. S. Habrochaites has members that are self fertile and others that require cross pollination. S. Habrochaites has medium to large showy yellow flowers. S. Peruvianum is an obligate outcrosser requiring insect pollination with compatible pollen to set fruit. S. Peruvianum has large showy yellow flowers. |

Some observations so far: Gold Nugget, Mohamed and Black Seaman all have flowers (various sizes) that are pale, pure yellow - the typical tomatoey hue

It's notable how some varieties show the orange / tangerine gene in their flowers: Khurma ja Orange Strawberry both have this characteristc, while another orange variety, Zolotoy Korol, has usual, pale yellow flowers.
![]() Black and green varieties all show that average light yellow color as well. ![]() |

I found an interesting paper by Kachanovsky et al, which has very nice pix comparing the fruit colour and flowers on red, tangerine, yellow, and yellow-tangerine.
It shows pale yellow flowers for yellow fruit, compared to the 'orange-yellow' deeper shade for red.. Personally I have 6 F2 plants from red X yellow crosses, but I haven't been able to distinguish any flowers to make an informed guess ![]() ![]() Also some of my 'red' OP's do seem to start out with plain yellow anthers and only darken as they mature. So I can't make a SWAG as to red vs. yellow... Here's a copy of the pdf which i downloaded. Excellent flower pix on the second page. ![]() |

Nice find Bower, it’s a helpful article to me and probably many other folks. Thanks for posting it.

Thanks for getting the picture out, Dutch. It's a good one!
![]() It is certainly no trouble to tell the tangerine and yellow-tangerine gene from the flowers, which is a great thing to know, whether it's a new OP you want to breed with or whether you're watching some lines segregating. In my grow this year, Datlo, Earl of Edgecombe, and Lescukovo Oranzove (orange fruit) all have the tangerine flower, and so do Bursztyn and Yellow Clusters (yellow-tangerine). It's pretty cool to know what's going on genetically, even though I haven't grown any of these before. ![]() |
