Effect of chilling acclimation on germination and seedlings response to cold in different seed coat colored wheat (Triticum aestivum L.)

Table 1 Chi-square (χ²) analysis for the F₃ generation for seed color segregation

Generation	Grain color				Total	Segregation ratio	χ²	Df	P-value
F₁	Yellow X Deep Purple				-	-	-	-	-
F₂	Yellow				-	-	-	-	-
F₃		Yellow	Medium Purple	Deep Purple
	Observed	111	-	30	141	13:3 ^a	3.413	1	0.06
