Fertility of a Hybrid between Distantly Related Species in Lilium

Abstract

The meiotic events in post-metaphase I stages in the PMC of the hybrid L. auratum platyphyllum×L. henryi were observed. Restitution nuclei were produced in 75.6% of the cells at telophase t, followed by equational division. At ‘tetrad’ stage, 91.2% of the cells were diads mostly with one or a few micronuclei. Only 1.6% of the mature pollens germinated normally.
