CHROMOSOME BEHAVIOR DURING MEIOSIS IN LOQUAT

Meiosis of PMC in loquat (Eriobotrya japonica Lindl., cv. ‘Longquan No.1’) was normal and synchronous in each anther. Stages were associated with morphology of buds and anthers. Bouquet-shaped chromosomes were formed in zygotene, but in diakinesis, most of the chromosomes formed bivalents which were in rod, V, O, heart, and dot shapes. In diakinesis univalents (0.98%) and tetravalents (2.94%) were observed. A few laggard chromosomes were observed at anaphase I.
