In the tepary bean thread I mentioned last year that I had found some F1 crosses in my grow-outs of my F2 populations of another dry bean cross (Dolloff X Brown Trout). I offered this seed free to HG first come first serve, and I had no intentions of growing it out myself as I do not typically like black beans. But the possibilities of a fresh F2 segregating in front of my eyes was too tempting so I did plant some of it myself. The earliest plants are starting to mature dry pods and I have been going through and shelling them to look for interesting plants. I'd estimate that at least half of the plants are solid black beans. But the non-black population is excitingly diverse. I'm glad I grew it out. I've attached a few pics but the color is terrible due to crappy lighting, but it will give some idea to how much color is segregating out of this F2 Mitla Black X (F2 Dolloff x Brown Trout). They are also segregating for plant structure, pod morphology and seed shape as well.    |

oxbowfarm: I planted a lot of that seed. Thanks for sharing. I'm about a week or two away from the start of my fall frosts, so I expect to be harvesting beans about then. The first pods of other varieties were already dried down when I checked on Sunday. I didn't make a map of where things went in the garden, but I expect these to jump out at me. Most everything else was planted in short rows: type-to-row. The oxbow farm hybrid clade was a very long row...

After growing inbred lines for some many years, growing out crossed material is just amazing! Every pod is like opening a new present! Those look really nice, oxbowfarm ! |

Shelled out a few more plants. Each line is an individual plant. Much better lighting this time.   |

I've also been growing this clade thanks to a generous donation by oxbowfarm. Mine are about 67% black. My favorite so far is a bean with the Brown Trout seed coat pattern, but with black coloration instead of brown.  The original cross was [(Brown Trout X Doloff) X Black Mitla] as discovered by oxbowfarm. Here are three of the pole/indeterminate segregates.  Here's what the general population of bush (not-pole) beans looks like.  Some of the plants were very vigorous and productive. Some of them were pikers. I'm saving seed this year from anything that produced mature seed. I have already harvested all of the more-or-less-bush beans. I haven't harvested any of the pole or very long tendril beans yet. They are much longer season, and don't seem suitable for my climate. We are about 5 weeks late with our fall frosts. I grew another segregating hybrid this year which was descended from Dutch Brown. It is currently one generation ahead of the Oxbowfarm clade. Last year I selected for earliness and for approximately-bush habit. I am often amazed at how much selection pressure can be put on a crop in a single growing season to move it closer to local adaptation: Especially with the mostly inbreeders like beans. The Dutch Brown cross is a good example. I expect the same from the Oxbowfarm clade next year. |

Dolloff carries a trait for reduced oligosaccharide production. It causes less flatulence when eaten. A bush bean with that trait would be a nice find.

I have not had a bean like that turn up for me, but I do have a couple with the Brown Trout/Jacob's Cattle/Anasazi pattern. That pattern seems to be slower to show up, it may be recessive to solid color. I also have noticed on Brown Trout that from year to year it will vary in white/color ratio, but I'm not sure what causes that effect. My favorite Trout pattern bean from this clade is similar in shape to yours but the colored pattern is red-purple mottled with dark brown/black. |

From an earlier harvest.  |

All of the beans in in the photo are F2 Mitla Black X (F2 Dolloff x Brown Trout) segregants from some Mitla Black cross plants in one of the rows of bush lines from the original Doloff x Brown Trout material. They have no name, it would be pointless to name them at this stage as there are tons of unfixed loci. |

I shared this variety with the world as "Oxbow Farm Black Anasazi". |

Neat looking bean.

I selected among these beans for bush habit, and short season, then added them to my general population. They are still there. The ones that I think of as Oxbow Farm Black/White Anasazi sure stand out... Thanks Tim. The black speckled horticultural bean came from the same cross.  |
