Was discussing polyploidy and mutation breeding with a colleague the other day and he came out with some experiential statements I've been unable to confirm. He's on leave now so I can't have a longer discussion til he returns. I thought I'd throw the following of his statements out there and see if anyone knows more 1. Polyploidy is cool, and pretty standard stuff in plants. However it's not an increase in secondary metabolites that is the biggest outcome for plants, polyploidy generally first confers an increased immunity to cold temps. Anyone know more? And can polyploidy change the actual phytochemical products of a species? 2. No point looking for gross floral morphology changes in a mutant population, flowers are the last things to mutate as the plant has a vested interest in passing on it's genetics using its current methods. So they protect the flowers, and work to make ornamental variatiations of floral morphology is much harder This one is relevant to me because I was hoping to find floral variations in a mutant population. Haven't seen them. If this line of work is pretty low yielding in terms of results I'll put it on the backburner

A long time ago I was a party to a convo about creating new strains of edibles via hyphal mating Most of the discussion was way over my head and still is, but the tek was ghetto and the results potentially identifiable without much equipment, no sequencing etc The tek was to culture two separate species on individual plates, each containing the same media Subculture two small sections of each species about 2cm apart onto a single plate Where they joined up, wait for sectoring to occur, and subculture each sector Fruit, and check results for morphological or environmentally distinct growing patterns Anyone done this? How viable a tek does it sound? How genetically distinct can the species be, for example a Pleurotus x Lion's Mane- would they be too far apart to hybridise? It sounds like fun, and easily quantifiable for macro level results ( ie, I'm not lookin for tiny changes, measurable only by sequencing, I'm looking for variations in fruiting shape ).

This documentary based on the 2008 book by the same name is about people obsessed with collecting, preserving, and crossing rare fruit species and varieties. It's almost if one traded a Trichocereus or medical plant obsession strictly for tropical fruit. It's pretty fascinating really. The story features among others two mango conservators from the Fairchild Tropical Botanical Garden hunting down a white fleshed mango and maintaining their 600+ variety mango collection and a Hondouran scientist with a very involved (1 seed in 1000 banana clusters!) Cavendish banana breeding program. It's on youtube now: Part 1 - The Evolution of Desire [44:33] Part 2 - Defenders of Diversity [44:33]

I am looking for some brugmansia pollen to try and hybridise some of my pure species as well as to further work on the hybrid i currently have. I would idelaly like a pink, peach, or similar brightly colored cultivar if possible. At present the planned first run of hybrids will be (Brugmansia Aurea 'yellow' x Brugmansia Suavolens) x Brugmansia Aurea 'White' (Brugmansia Aurea 'yellow' x Brugmansia Suavolens) x Brugmansia Candida 'Single White' Brugmansia Aurea 'White' x Brugmansia Candida Brugmansia Aurea 'Yellow' x (Brugmansia Aurea 'yellow' x Brugmansia Suavolens) I would like to add a few extras in there if someone could sell, trade or donate me some pollen. I wont need it for around 1-2 weeks so no real rush.
