The family Malvaceae is one of the largest flowering plant families with 4465 species recorded worldwide belonging to 245 genera. 35 species are reported from Nagpur district. Plants have ornamental, economical and medicinal value. Though morphological pollen studies in these plants are published, very meagre quantitative data is available about pollen production and pollen:ovule ratio, which provides insight into breeding system of the plants. This project was, therefore, undertaken to evaluate the same in some common members of Malvaceae found in Nagpur city. 14 species belonging to 8 genera of Malvaceae were evaluated. With limitations of less sample size and smaller geographical area, this preliminary study has presented quantitative data on pollen production and pollen:ovule ratio. In our future studies, pollen production and P:O ratios would be studied in different regions of wider geographical area in different seasons and with larger sample size so that relationship of all these factors on breeding system can be better understood.
