  We study the latitudinal distribution and temporal evolution of the sunspot
penumbra-umbra ratio (q) for the even and odd Solar Cycles 12-24 of RGO sunspot
groups, SC21-SC24 of Debrecen sunspot groups and Kodaikanal sunspot dataset for
SC16-SC24. We find that RGO even (odd) Cycles have q-values 5.20 (4.75),
Kodaikanal even (odd) cycles have q-values 5.27 (5.43), and Debrecen cycles has
q-value 5.74 on the average. We also show that q is at lowest around the
Equator of the Sun and increases towards higher latitudes having maximum values
at about 10-25 degrees. This is understandable, because smaller sunspots and
groups locate nearer to Equator and have smaller q-values than larger sunspots
and groups, which maximize at about 10-20 degrees at both hemispheres. The
error limits are very wide and thus the confidence of this result is somewhat
vague. For Debrecen dataset we find a deep valley in the temporal q-values
before the middle of the cycle. We show that this exists simultaneously with
the Gnevyshev gap (GG) in the graph of the total and umbral areas of the large
sunspot groups. Other databases do not show GG in their q-graphs, although GG
exists in their temporal total area and umbral area.
