Figure 3. Flowering time of plants from the Test cross.

Spring1, an early flowering mutant, was crossed with Jester plants and the resulting F1 plants were then crossed with Jester in the Testcross (♂(♂“spring1 x ♀Jester”) x ♀Jester). The Testcross progeny were grown in long day conditions and scored for flowering time. Graph showing the distribution of flowering time of plants that were classified as early flowering (n = 83) and late flowering (n = 95) compared with Jester (n = 6) and F1 plants (n = 32). The class with ≥11 nodes includes plants that had up to 21 nodes, but had not flowered by the time scoring was terminated at 69 days after germination. Plants that were “unclassified” or died young are not included. As parental and progeny plants grew at different rates, flowering was measured as the node number on the main axis at flowering.
