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

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

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
  1. χ20.05 = 3.84, χ2 < χ20.05 indicates no significant difference between the observed and expected ratios
