Description SADCIICRISAT SMIP jointly naluated wth NARS rhr par1 millr! gennplasm
from Tanzanta andZimbabwe in 1988189, andfrom Namibia in 1991/92 The
obtectiva wre to tdentil.v. some su'o enor accessions that could be ra.~ td.iv t m.
protied through gnd mars selertion or Itmired backcrossing and then release these
back ro the fanning rmmuniryfor mitivation, and to select accessionr that could
be tncorporatrd into he breeding program by crossing to create a dit~rntjed
segregatingpopulation/rom which new improved vanntrs could be drveloprd
Much heterosis tigor was observed in crossa betu~ern local landrace sanety
