The frequency distribution of fiber quality traits and dynamic change of fiber length during development.

<p>The mean values of fiber length (a), strength (b) and micronaire (c) obtained from four-year data of BC₁S₁ family lines. Average phenotypic values for parents (<i>G. hirsutum</i> acc. TM-1 and <i>G. barbadense</i> cv. Hai7124) are indicated by arrows. (x-axis: phenotypic value; y-axis: number of lines). (d). TM-1 and Hai7124 cotton fiber length at different development stages; (e). TM-1 and Hai7124 cotton fiber elongation rate (increasing length per day) at different development stages. Error bars are the standard deviation calculated with seeds from six biological replicates.
