Arid vegetable genetic resource-conservation and utilization for nutritional and income security under hot arid agro-climate

Description

The  vast  and  diverse  land-scape  of  hot  arid,  semi-arid  and  tribal  area  of  north-western  India  is  yet  not getting  logical  thought  for  resource  based  production  system  and  the  native  crop—plants  both  annual  and  perennials are  drought  tolerant  and  playing  vital  role  in  providing  nutritious  food  and  eco-restoration.  Here,  systematic cultivation  with  prioritized  vegetable  crop-plants  is  rare,  un-organized  and  marketable  produce  is  quite  marginal, and  this  is  only  because  of  lack  of  matching  genotypes  and  approaches.  Traditionally,  kachri  (Cucumis  melo  var. callosus  /  agrestis),  kakadia  (Cucumis  melo  var.  momordica),  mateera  (Citrullus  lanatus),  tinda  (Praecitrullus fistulosus)  and  guar  (Cyamopsis  tetragonoloba)  is  grown  with  mixed  cropping.  Besides,  khejri  (Prosopis cineraria)  has  significant  role  in  long-established  farming  system,  and  its  tender  pods  are  vegetable  use.  The crop-genotype  studies  over  45  vegetables  at  CIAH,  Bikaner  from  1995-2015  demonstrated  that  there  is magnificent  scope  in  obtaining  high  quality  yields  adopting  HBCPSMA  concept,  provided  trait  specific  genotypes. At  Bikaner,  systematic  collection  resulted  to  evaluation  of  1725  accessions  and  out  of  them  1060  germplasm deposited  at  NBPGR.  Based  on  characterization,  about  500  germplasm  utilized  in  improvement  work  and 17 varicties  released  and  15  genotypes  are  in  pipe-line.  With  khejri  models,  better  yield  in  prioritized  vegetables  and 
income  @  Rs  75,000—2,25,000  ha/yzar  is  obtained  in  comparison  to  traditional  cropping  (23,000—42,000).  Thus, the  technological  advancement  in  arid  vegetables  is  a  key  to  success  toward  better  economic  returns  and nutrition  to  the  inhabitants  at  resource  poor  environment.
