• At present, meiotic studies have been carried out on a population basis for assessing the genetic diversity in 38 accessions belonging to 6 species, namely S. barbata (n=18), S. glauca (n=9, 18, 36), S. megaphylla (n=18), S. palmifolia (n=18, 27), S. tomentosa (n=18) and S. verticillata (n=27), of the genus Setaria from different parts of India. For S. barbata and S. megaphylla, the chromosomal counts of n=18 represent the first reports from India. For S. glauca, 3 cytotypes occurring as diploids, tetraploids and octaploids are reported which also show some marked differences in their morphological features. The meiotic behavior in some populations of S. barbata and S. palmifolia (n=27) was found to be highly abnormal with low pollen fertility.
