Morphological and cytological assessments reveal pollen degradation causes pollen abortion in cotton cytoplasmic male sterility lines

HIGHLIGHTS

• What: The study provides a theoretical basis for utilizing CMS in hybrid breeding and in-depth investigation of the dominant configuration of cotton hybrid combinations mechanisms of sterility and the role of sterile and restorer genes. † QY and JS contributed equally to this work. The survey was repeated five times, with at least three flowers per plant were examined each time (Liu et_al 2018).
• Who: Qingyu Pei from the Two ­, segregating populations of cotton were established using cytoplasmic sterile lines (HaA and A, maternal) and restorer lines (HaR and R, paternal), designated as , (HaA × HaR . . .
