%X Multiseed (<i><span style=\"font-family:Verdana;\">msd</span></i><span style=\"font-family:Verdana;\">)
mutant sorghum [</span><i><span style=\"font-family:Verdana;\">Sorghum bicolor</span></i><span style=\"font-family:Verdana;\"> (L.)
Moench] lines with greatly increased seed numbers were developed. It was
originally thought that the </span><i><span style=\"font-family:Verdana;\">msd</span></i><span style=\"font-family:Verdana;\"> trait
could increase grain yield several times in comparison with the wild type from
which the mutant was derived. However, in a small plot trial, </span><i><span style=\"font-family:Verdana;\">msd</span></i><span style=\"font-family:Verdana;\"> seed yield decreased when compared
to the parent line. Herein we report results that </span><i><span style=\"font-family:Verdana;\">msd</span></i><span style=\"font-family:Verdana;\"> seed yield remained either unchanged or slightly increased in
comparison to the parent line. We suggest that attempts to measure </span><i><span style=\"font-family:Verdana;\">msd</span></i><span style=\"font-family:Verdana;\"> sorghum seed yield were complicated
due to systematic errors associated with the post-harvest processing methods,
including threshing and pneumatic winnowing equipment that was used for
harvest. </span><span style=\"font-family:Verdana;\">That is, seed recovery and seed
loss from individual panicles w</span><span style=\"font-family:Verdana;\">ere </span><span style=\"font-family:Verdana;\">affected by the post-harvest
processing.</span><span style=\"font-family:Verdana;\"> When evaluating sorghum grain yield of types with
different seed sizes, threshing and seed cleaning harvesting methods should be
optimized for each sorghum line.</span>
