Abstract
The objective of this paper is to record the results of the study to make the karyotyping characterization of five S. indicus populations from Argentina by using Image Analysis System (IAS).
The objective of this study was to make the karyotyping characterization of 5 S. indicus populations from Argentina by using the Image Analysis System (IAS). This native grass species has 2n = 36 according to previous records, the karyotype is composed of 13 metacentric pairs and 5 submetacentric pairs; pair N° 2 has terminal satellites at the short arms. The mean chromosome length in 1.16 μm ranging from 0.76 to 1.61 μm. To determine the chromosome parameters the measurements were analyzed using the image analysis system. No cytotype differences were found throughout the populations analyzed.
