What you have there is a grex defined as grex: A group name for all plants derived from crossing the same two or more parent species; the herd or hybrid swarm. found at glossary.gardenweb.com/glossary/grex.htmlA landrace has to have roughly the same phenotype or have the same morphology from one plant to the next. Having all the colors of the rainbow with all possible sizes is not a landrace but can be considered the raw material for a landrace that would allow for the selection for each climate and soil conditions it is sent to as stated by long island seed. The main feature for a land race is it has to be distinct from other such cultivars it came from to allow for identification. Landrace populations are often highly variable in appearance, but they are each identifiable morphologically and have a certain genetic integrity. Farmers usually give them local names. A landrace has particular properties or characteristics. Some are considered early maturing and some late. Each has a reputation for adaptation to particular soil types according to the traditional peasant soil classifications, e.g. heavy or light, warm or cold, dry or wet, strong or weak. They also may be classified according to expected usage; among cereals, different landraces are used for flour, for porridge, for 'bulgur', and for malt to make beer, etc. All components of the [plant] population are adapted to local climatic conditions, cultural practices, and disease and pests." Harlan, J. R., Crops and Man, American Society of Agronomy and Crop Science Society of America, Madison, Wisconsin, 1975 |

I'm thinking that I'll reserve free copies for people that have sent me seeds from their gardens for three years in a row,  or that have previously sent silver dimes my way. ;D But all hope is not lost: It'd be really clever to have some proofreaders that don't agree with me in all things.  |

For seed saving she said you have to at least take some kind of notes and to maintain a variety you need isolation practices.
I wonder how the native Americans ever transformed the corn, squash, and bean genomes into something useful since they didn't read and didn't practice isolation?[/b][/quote] Indeed. Intuition combined with good visual memory and good taste memory, filtered through disease and climate pressure in the field, can make effective non-literate breeding practices for selection of locally adapted varieties. |

By the way a petard is explosive charge for breaching fortification: a small explosive charge or grenade used to blow a hole in a door, wall, or fortification be hoist with your own petard to be the victim of your own attempt to harm somebody else www.bing.com/Dictionary/search? q=....ion&FORM=DTPDIA Yes, that is what I said.circumspice your comment "develop seed bearing varieties of plants that propagate vegetatively & therefore carry viral loads that threaten their continued existance" So Joseph is trying to come up with new plant viruses that will kill off plants? Or does it mean he is trying to come up with horizontal resistance to viruses? Horizontal resistance. I didn't state that clearly. Sorry.

I think petitvilaincanard should read Bambi and see what Thumpers mother had to say. Enough is enough.Some of us want to read Josephs post not your bitter replys. Well that was my 2 cents worth.

Hmmm: Thumper's mother sounds just like my grandmother.
There is a "Report to Mod" link on the bottom of every post. When used, it calls attention to itself by placing a bolded message at the top of every page on the site for every moderator. Besides being used for reporting spam, I recommend it as a way to put peer pressure on the moderators.
Also since most moderators only check in occasionally, they can be overwhelmed by the number of posts and never see problems.

For what it's worth, I reckon a inbreeder landrace like tomatoes might be really hard to develop, without intentional crossing and lots of growouts.
But in an extreme environment, with quite harsh environmental filters, a landrace might be quick to develop. Surely the plasticity of the taxon is also important? I think it might be really tough to set specific periods for when a landrace actually is a landrace and no longer ' proto'. But, hey everyone else is being definitive, so I'm voting for exactly 7 years 3 months and 15.3 days til it's a landrace.
... it's the English language after all, meanings flex and change, we misunderstand each other, and grex, landrace, multiline, hybrid swarm, who really cares? the genes are just out there, interacting with each other and the environment, has anyone asked them?
And this is all too much fun to start bitching about!
