Chromosome behavior during meiosis in pollen mother cells from Saccharum officinarum × Erianthus arundinaceus F₁ hybrids.

ABSTRACT:

Background

In recent years, sugarcane has attracted increasing attention as an energy crop. Wild resources are widely used to improve the narrow genetic base of sugarcane. However, the infertility of F₁ hybrids between Saccharum officinarum (S. officinarum) and Erianthus arundinaceus (E. arundinaceus) has hindered sugarcane breeding efforts. To discover the cause of this infertility, we studied the hybridization process from a cytological perspective.

Results

We examined the meiotic process of pollen mother cells (PMCs) in three F₁ hybrids between S. officinarum and E. arundinaceus. Cytological analysis showed that the male parents, Hainan 92-77 and Hainan 92-105, had normal meiosis. However, the meiosis process in F₁ hybrids showed various a
