Abstract

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 (LLVJ arcessionr unth tmproved relellred vanetin Yteld supenonty of 6 8- 46 6% over the released vanety in Zimbabwe (PMV 2) w observed among intervaneta1 hybn& unth LLVs from Zimbabwe.

In backcross studies to improve Okashanc I , progenies simdar to O k a s h a ~tn gnln sire and ttme to mtunry, but unih up to 24% supmoriry in yield and other tratt advantap, were tdrntified in the thtrd backcross ene era ti on. This study suggesrs that conrtderable potential exists for tmprovtng yirld and other traits prefrned by fanners through greater uttllration of LLVs tn bnrding program
