Table 1 The Chi-square (χ2) goodness-of-fit test ratios of leaf shape segregation in BC and F2 populations

From: Map-based cloning and promoter variation analysis of the lobed leaf gene BoLMI1a in ornamental kale (Brassica oleracea L. var. acephala)

Populations Total plant number Number of lobed-leaf individuals* Number of unlobed-leaf individuals* Expected ratio χ2a
F1 16 16 0
F2 120 92 28 3:1 0.18
BC1P1 850 429 421 1:1 0.08
BC1P2 200 200 0
  1. aχ2 > χ20.05 = 3.84 was considered significant
  2. *Lobed-leaf plants and unlobed-leaf plants were determined at the seedling stage by visual inspection
