Genome sequencing identified novel mechanisms underlying virescent mutation in upland cotton Gossypiuma hirsutum

Table 1 Segregation of leaf color in the F₂ population of the cross-breed between the wild type and the virescent mutant of Sumian 22 cotton

Cross	Wild type S22 × Virescent mutant S22
Number of green leaves plants	704
Number of yellow leaves plants	263
Total number of plants	967
Expected ratio	3:1
χ²	2.49

χ²_0.05 = 3.84, χ² < χ²_0.05 indicates no significant difference between the observed and expected ratios
