I'm seeing individual seed packets with mixed varieties.
If I was to save the resultant offspring, would there still be variety, or, after successive generations, would they all start to look the same?

I guess that depends on how many you have of each one. Beets and carrots get inbreeding depression.
There's a good article on line in a book called Breeding Crop Plants by Herbert Kendall Hayes. Google: breeding beets
That should get you there.

If you keep planting the offspring, and letting them cross, eventually you end up with a landrace, I think.

If you actively select to keep the different colors you may be able to keep them distinct. I know with beets you will start to get a bunch of intermediate colors show up. The evidence for that is Alan Kapuler's 3-Beet Grex which has a bunch of interesting color combinations from a start of three different varieties.
I don't know really anything about how color is inherited in carrots or what might happen if you let them cross. Presumably some of the colors are dominant to others and you wouldn't have the same ratio of color that is in the mix.

I am sort of banking on being able to select colors. I have always wanted black carrots, but a seed source has become elusive (most of the black cultivars are in Turkey, and rarely leave). Si it has been my plant for a while (as soon has I have enough other seed I want to make up the minimum order) to try out Kokopelli's De Djerba carrot. This carrot comes in 3 colors black, purple and orange (in a 1:2:1 ratio, classic Punnet incomplete dominance) my plant had always been that, come harvest time, I would carefully look at each carrot before I pulled it. Oranges and purples would be harvested an eaten, blacks would be left to seed. So by the next year or the year after (depending on whether De Djerba is a annual or biennial carrot), I'd have a population of all blacks.

If I was to save the resultant offspring, would there still be variety, or, after successive generations, would they all start to look the same? Plants are very likely to be pollinated by their closest neighbors... And unlikely to be pollinated by plants from further away. So when I am growing colored plants for seed, I plant the yellows together on one end of the row, and then the oranges together, and then the reds together, etc. This maintains the colored lines, and allows for crossing between colors. For some species like corn, I grow somewhat isolated patches of each color. I maintain a balance from year-to-year between the colors by planting seed stock in the ratio that I want to maintain. I'd expect this carrot to be male sterile... Don't know how I'd use it in a breeding program. |
