The Cyto-morphological Studies in Physalis minima Linn.

Abstract

Cyto-morphological studies in a diploid natural population of Physalis minima Linn were done. It was a diploid natural population recorded behind Jal Mandir on Parasnath hills. Qualitative and quantitative parameters were investigated. Ten morphological characters like height of the plant, number of branches per plant, number of branches from main stem, number of nodes, length of internodes, number of heads per plant, length of leaf, breadth of leaf, length/breadth ratio of leaf andlength of petiole were recorded and statistically analyzed. Cytologically, the population showed, gametic number as n= 12. Most of the pollen mother cells were found to be normal; however, some abnormalities were also recorded. Clumping of chromosomes recorded in both meiotic phases i,e. metaphase-I and anaphase-I. Along with it, at metaphase-I, the anomalies recorded as formation of univalents, multivalents and precocious separation of chromosomes. Anaphase-I showed chromosomal laggards, simple chromosomal bridges and unequal separation of chromosomes as anomalies. The half chiasma per chromosome was 0.87. Pollen sterility was 6.00 percentages.
