The somatic chromosomes of standard indica diploid rice, IR 36, were squash
ed on glass slides and stained with Giemsa. The condensation patterns (CP)
of prometaphase chromosomes were quantitatively analysed using CHIAS III so
ftware. The relative length and centromeric index (CI) were converted from
CHIAS III to numerical data and calculated by EXCEL program. The ideogram b
ased on CP of indica rice was established. There were 2 pairs of satellite
chromosomes and the result was confirmed by fluorescence in situ hybridizat
ion using 45S rDNA as a probe.
