In article . 10,
Victoria Clare writes Kay Easton wrote in : So you've made me think ... Tomato is Lycopersicum. Blue is a colour that pops up frequetnly in Solanum - woody nightshade, aubergine etc. Are there any Lycopersicum with blue flowers? Google doesn't seem to know of any: every reference I could find is to yellow flowers. How many did you find? There are only 7 species of Lycopersicon in total. Two (tomato and L rostratum have yellow flowers, so that's only 5 left to check!) Though as tomatoes started off being imported as a poisonous decorative, and have mutated into all sorts of edible forms ( WHO decided to do that, and how many stomach aches did they suffer before it worked?), Well - maybe none! Solanum has many species with edible fruit, and Lycopersicon is close enough for the tomato to have originally been classified as Solanum, so maybe it was edible all along and the breeding has just been for bigger and juicier fruits. I bet it would be possible to breed one. Not necessarily. To get a particular colour, you need the genes for producing the chemical to provide that colour, and if it's not there in the close relatives, you're not going to be able to breed it in. Blue and yellow don't seem to occur that often in the same plants (somebody is going to say 'pansy') - blue and pink go together a lot easier - look at all the forget-me-not/lungwort/borage group. Solanums have purple (potato, aubergine) and white (potato) but do they have yellow? Datura/Brugmansia have both purple and yellow. But if you can't find a blue/purple close enough to tomato to cross breed, you're not going to get a blue flowered tomato. Didn't we have a similar discussion about potato flowers (which do seem to be more variable than tomato ones)? Never seen a yellow one ;-) -- Kay Easton Edward's earthworm page: http://www.scarboro.demon.co.uk/edward/index.htm |

There are so many poisonous members of the Solanum tribe that I would be more than worried about eating any one other than the commonly culivated ones like potatos and tomatos. Solanum muricatum has been in cultivation for a very long time: it's an Inca crop. In fact, I think that makes it a longer-established edible than the tomato, which I understand was bred into edibility quite recently (C16th or so). An awful lot of the Solanums are eaten - apart from the ones we've discussed in urg - S aethiopicum s agrarium S aviculare S duplosinuatum S ellipticum S macrocarpon S pierreanum S piliferum S quitoense S saniwongsei S topiro S trifolorum S uporo - fruits of all these are eaten S anomolum S diversifolium S torvum - fruits used as condiment S andigenum S fendleri S jamesii - tubers are eaten .. and that's without even looking at any of the other Solanacaea genera That was the most interesting post I have read for a very long time. I shall print it. Franz |
