Seeds

From BadWiki

As a quick rule for cross-pollination if two plants have the same scientific first name (genus) and same scientific last name (species) then they will likely be able to cross.

I am going to try and cover the commonest vegetables so this isn't an exhaustive guide.

Key * means plants freely cross (troublemaker) - # means do not easily cross (friend). BI = biennial, AN = annual

  • Beets/Beetroot and Chard - * BI - Beta Vulgaris - Swiss Chard, Beets/Beetroot, Spinach Beet, Fodder Beet, Sugar Beet and Wild Chard (Sea Beet). So for this first one on the list the '*' means that all these varieties will freely cross.
  • Carrot - Daucus Carota - * BI - All varieties of carrot will cross and they will also cross with wild carrot common names of which are bird's nest, bishop's lace, Queen Anne's lace
  • Parsnip - Pastinaca Sativa - * BI - Only a handful of parsnip varieties are grown commonly but they will all cross
  • Turnip family - Brassica Rapa - * BI - the turnip family covers turnips, bok choy, mizuna, tatsoi and Chinese cabbage, amongst others, which will all freely cross.
  • Cabbage family - Brassica Oleracea - * BI - Cabbage, Brussel Sprouts, Kohl Rabi, Kale, Broccoli/Calabrese, Cauliflower, Collards.
  • Celery - Apium graveolens - * BI - few varieties grown but all will cross with each other and the wild form sometimes called Smallage
  • Onion - Allium Cepa - * BI - bulb onions, shallots, Egyptian onions. Will NOT cross with chives (Allium schoenoprasum)
  • Leek - Allium ampeloprasum - * BI - will cross readily with other varieties but few varieties are usually grown
  • Lettuce - Lactuca Sativa - # AN - butterhead, crisphead, romaine/cos, looseleaf, oak leaved, celtuce. The first on the list that doesn't cross so readily with its cousins. You are still better to leave 50 - 100 feet between varieties you are saving seed from.
  • Pea - Pisum sativum - # AN - another 'friendly'. Because of the structure of the flower, these don't easily cross. Includes garden pea, petit pois, sugar snap, mangetout, maple and marrowfat.
  • Cucumber - Cucumis sativus - * AN - salad cucumber and gherkins. The Armenian cucumber is actually a type of melon (see below) and will not cross.
  • Melon 1 - Cucumis Melo - * AN - honeydew, canteloupe, canary, musk melon, Armenian cucumber.
  • Melon 2 - Citrullus Lunatus - * AN - Watermelon - Will not cross with Melon 1 above.
  • Cucamelon - Melothria scabra - * AN - Will not cross with melon 1 or melon 2 above.
  • Corn/Maize - Zea mays - * AN - sweetcorn, dent, flour, flint and (colourful) ornamental
  • Spinach - Spinacia oleracea - * AN - This is true spinach and not Spinach Beet (which is beta vulgaris), see above. All varieties will freely cross.
  • Swede/Rutabaga - Brassica Napus - * BI - also includes canola and Russian red kale so crosses with these.
  • Beans 1 - Phaseolus Vulgaris - * AN - Common Bean, kidney bean, navy bean, pinto bean, borlotti, wax bean, pole bean
  • Beans 2 - Phaseolus coccineus - * AN - runner bean/multiflora, greek gigantes
  • Beans 3 - Phaseolus Lunatus - * AN - butter bean, lima, siera, Madagascar
  • Beans 4 - Vicia faba - * AN - Broad/Fava/Faba/Horse and field bean
  • Squash 1 - Summer Squash - Cucurbita Pepo - * AN - Zucchini/courgette, crookneck, patty pan, Delicata, acorn, spaghetti includes some pumpkins and gourds
  • Squash 2 - Winter Squash - Cucurbita Maxima - * AN - Hubbard, turban, buttercup, banana, kabocha, sweetmeat
  • Squash 3 - Butternut family - Cucurbita moschata - * AN - butternut, golden cushaws, musquee de Provence, Naples long squash, Seminole, calabaza, trombocino
  • Tomato - Solanum lycopersicum - # Perenial grown as an annual - too many varieties to mention. Do not easily cross because of the flower structure/pollination method.

Just a last word or two; even the friendly '#'s need to be separated by 50 - 100 feet if you're in this for the long haul and you want seeds that remain true to type for decades to come. Also, you need to try and maximise the population when pollination occurs. The brassicas on one of the worst in that they'll need a population of 50+ plants to allow for the genetic diversity to remain within the population and keep it strong and healthy.
