ABSTRACT
In order to identify groundnut genotypes suited for cultivation under limited rainfall conditions, around 130 genotypes/crosses from different breeding trials were screened for higher yield then local check varieties under simulated drought conditions in summer season for three years i.e. 1995, 1996 and 1997. Total twelve promising crosses/genotypes (the crosses were sixth generation crosses) including three check varieties were selected for study. They were evaluated for pod yield in comparison with three check varieties in kharif seasons of the years 1999, 2000 and 2001 at four naturally drought prone locations in addition to Junagadh. The crosses GG-2 X NCAC 17135, GG-2 x PI 259747, J-11 x PI 259747 and S 206 x FESR-8, kisan x FESR-S-PI-B1-B and the genotypes JB 223 and 224 recorded consistently superior and stable yield for the three years at all the locations. Hence, it is suggested that these lines/genotypes could be grown under regions of limited rainfall. These lines may be used as parents in breeding programmes for developing drought tolerant groundnut cultivars.
