a M and N represent mutated and normal alleles, respectively; see Supplementary Table S1 for markers used in distinguishing different alleles.
b Four were completely lintless and one was close to lintless.
c Four were close to lintless.
d Weight of lint as a percentage of total seed cotton weight.
e Values with the same letter were not significantly different determined by Student’s t-test.
