Pollen performance under controlled temperatures and chromosome stability of diploid and tetraploid citrus
[Background] Polyploidization plays a major role in citrus breeding, particularly in generating triploid hybrids through controlled crosses between diploid female and tetraploid male parents. However, limited information is available on how polyploidy affects pollen performance in citrus, and in par...

| Resumo: | [Background] Polyploidization plays a major role in citrus breeding, particularly in generating triploid hybrids through controlled crosses between diploid female and tetraploid male parents. However, limited information is available on how polyploidy affects pollen performance in citrus, and in particular, how temperature influences these processes. In this study, we compared pollen viability under field conditions and pollen tube growth at different temperatures in diploid and tetraploid genotypes, and assessed whether the observed differences were related to genomic instability caused by the tetraploidization treatment. |
