Meiosis is a key feature of eukaryotic sexual reproduction that properly reduces the chromosome number of gametes in anticipation of fertilization and the reconstitution of the diploid state. It also increases the genetic variability in the population of organisms from one generation to the next and variations are very important for the process of evolution. During present study the meiotic course in Chlorophytum laxum R. Br. and pollen fertility have been detected. For this, the plant materials fixed in Carnoy’s fixative and observed the detailed meiotic behavior in Chlorophytum laxum by standard squash method in 1% acetocarmine. Pollen viability was tested with 1 % acetocarmine and 0.5 % TTC stain. During the present study it is observed that along with the normal meiotic behavior of PMCs showed varied range of abnormalities in Chlorophytum laxum like chromosome stickiness, unequal distribution of chromatin material, change in orientation and unreduced gametes, etc. without any treatment. Pollen fertilityy was found to be maximum in acetocarmine: glycerine i.e. 93.57% compared to TTC (2, 3, 5- triphenyl tetrazolium chloride) i.e. 59.76%.
