I do not think that would work. An improved meyers lemon is simply a meyers lemon that is grafted onto trifoliate orange root stock. The meyers lemon is a hybrid of a citron and mandarin orange. So the seeds will revert to anything from a citron to an orange type fruit. It might breed true, you just don't know. Also, I understand the seeds don't stay viable very long, maybe days. The trees are not very cold hardy I have lost small trees with temps in the upper 20's and I live at latitude 30 degrees. The trees like warm wet winters and hot humid summers. We grow them from cuttings and grafting, not seeds. I like the meyers lemon tree over the "improved"meyers lemon because if it does freeze the plain meyers lemon tree may come back from the roots. The Improved you could only get rootstock. All that said if you still want to try, get a meyers lemon and plant the seed immediately. hope this helps.
I had the exact same idea as you, but I live on a different continent from anywhere that someone I know might have meyer lemon. So I got a friend in California to send a couple of Meyer lemons to me when I was in the USA in August. I took out the seeds, and took them with me to India, and stuck them in the soil of some houseplants. Several germinated within 2 months, and a couple more have germinated now that the weather is warming up.
I know that they won't come exactly true to the parent, but I am hoping that they might be nice small trees that might give some kind of nice citrus. I'll keep one or two in pots to move in and out seasonally. If I get a few established, I'll try one in the ground in my greenhouse, which does go down to -5C every night for at least 2 months of winter, but over 0C every day. It might not last, but I'm eager to try anyway.
