Differences in homologous and heterologous nucleocytoplasmic interactions of cytoplasmic male sterility lines in Gossypium barbadense.

ABSTRACT: The utilization of crop hybrids plays an important role in crop breeding and production, and the innovation of the male sterile germplasm is the basis for this utilization. Cotton has a very clear hybrid advantage, and the hybrid advantage in yield and quality has been widely utilized in cotton breeding. However, the exploitation of heterosis in cotton is currently dominated by cytoplasmic male sterility (CMS) lines. These CMS lines are found only in Harknessi cotton. They have a single cytoplasmic origin. Additionally, they exhibit a significant negative effect of cytoplasmic-nuclear interactions. To minimize this effect, it is necessary to select and breed CMS lines. In these CMS lines, both the cytoplasm and nucleus should originate from the same variety. However, no homologous cytoplas
