dc.description.abstractPigeonpea  (Cajanus  cajan  (L. )  Millspaugh)  is  an  import ant   grain  legume  grown  in  t ropical  and  subt ropical  regions  of   t he  world.   Narrow genet ic  base  coupled  wit h  low  levels  of   resist ance  against   import ant   biot ic/ abiot ic  st resses  in  cult ivat ed  pigeonpea  is  t he  major const raint   aff ect ing  it s  product ion  and  product ivit y  globally.   Wild  Cajanus  species  are  t he  reservoir  of   many  import ant   genes  including resist ance/ t olerance  t o  diseases,   insect ­pest s  and  drought ,   and  good  agronomic  t rait s  and  can  be  ut ilized  t o  improve  t he  crop  cult ivars, enrich  variabilit y,   and  broaden  t he  genet ic  base.   Ut ilizat ion  of   wild  Cajanus  species  has  cont ribut ed  f or  t he  development   of   cyt oplasmic male  st erilit y  (CMS)  syst ems  f or  pigeonpea  improvement .   Prebreeding  populat ions  involving  promising  wild  Cajanus  accessions belonging  t o  secondary  and  t ert iary  gene  pools  as  donors  and  popular  pigeonpea  cult ivars  as  recipient s  were  developed  f or  enriching variabilit y  f or  pigeonpea  improvement .   Considerable  variabilit y  was  observed  in  t hese  populat ions  f or  morpho­agronomic  t rait s  and  f or biot ic  st resses.   Two  advanced  backcross  populat ions  derived  f rom  wild  Cajanus  species  are  being  genot yped  t o  ident if y  QTLs associat ed  wit h  agronomic  t rait s  f or  f urt her  deployment   in  pigeonpea  improvement   programs.   Agronomically  desirable  and  disease resist ant   int rogression  lines  have  been  ident if ied  and  shared  wit h  breeding  programs  f or  developing  new  high­yielding  and climat eresilient   pigeonpea  cult ivars  wit h  a  broad  genet ic  base.en_US
