Morphology of the Pachytene Chromosomes of Physalis angulato L.

Abstract

Pachytene chromosome morphology of Physalis angulata L. (2n=48) was studied. The 24 chromosomes were identified individually. Their diagnostic features and an idigoram constructed on the basis of total chromosome length, length of chromatic and achromatic segments and arm ratios are provided. Chromosome 15 is the nucleolus organiser. The twenty four bivalents reflect the occurrence of 2 genomes of twelve bivalents each. Considerable morphological similarities exist between the two genomes.
