N1triVos F2 seedlings started coming up on Thanksgiving. Now, just 8 days later, the largest is 10 cm. tall, with 9 leaves. The second largest is 8 1/2 cm., with 7 leaves, but its leaves are wider, so it has more leaf area. I can already see segregation for some traits, but not the ones that matter. Seedlings number 5 and 6 came up overnight. I expect more will come up.
The N1triVos seedlings are next to a pot of finger lime seedling. Finger limes are about 6 weeks old, I think, and in good health. But they are less than 1/2 as tall as the tallest N1triVos F2 seedlings. The finger limes have more leaves, but less leaf area.
Precocity in apples is best measured by counting leaves to first flowers. I mean when comparing populations not growing in near identical conditions. So I am counting and recording number of leaves as a measure of precocity, hoping I'll find it is true with citrus. But I am seeing differences in days of growth between nodes, so I have my doubts.
