Exploring the Differences in Traits and Genes between Brown Cotton and White Cotton Hybrid Offspring (Gossypium hirsutum L.)

To explore the differences between brown cotton and white cotton, we hybridized the brown cotton P26 strain and the white cotton variety TM-1 and selected the F2 generation for investigation and research. The results revealed differences in morphological and yield traits between white cotton and brown cotton. Transcriptome analysis revealed differences in the expression levels of flavonoid synthesis pathway genes and transcription factor genes. The MYB3 transcription factor (Ghir_D07G002110) may regulate the CHS, CHI1, and F3H genes.
