Description Modified SSD procedures viz., single capsule
descent - Bottom (BSCD), single capsule descent
Middle (MSCD), single capsule descent - Top (TSCD) and
single capsule descent - General (GSCD) were evaluated
in three crosses of sesame namely, (GS-12 x TC-25) AT-
1, PDP-1-2 x JLT-2 and RCR-3 x Vinayak (M) to study the
relative differences among the procedures. Sign.ificant
differences among the F5 progenies in all the procedures
of crosses were observed for seed yield and
majority of yield component characters like total
number of capsules, number of productive capsules and
number of primary branches. Among the procedures BSCD
had exhibited superiority compared to other procedures in general

across the crosses for yield and yield attributes
revealed that BSCD was superior. Further, when method
means were considered cross-wise, BSCD still maintained
superiority followed by GSCD procedure for majority of
the characters studied. Though MSCD had an edge over
the crosses for some of the characters when considered
cross-wise, it was superior only in cross II. In
general, across the crosses as well as cross-wise,TSCD
procedure observed to be ineffective for yield and
yield attributes.
Besides the mean values when the best line
and top· few lines were considered, still BSCD procedure
maintained its superiority for majority of the
characters. GSCD procedure also retained bet~er lines
specially in cross I and cross III for some characters.
MSCD procedure was better in general in cross II for
yield and some of the yield ·component characters.
However, compared ·with the other crosses MSCD procedure
was not appreciable. The lines derived from TSCD procedure
were not promising for seed yield and majority
of the yield component characters studied in any cross
when compared to the lines of other procedures
