Abstract

A study was conducted during winter season (rabi) 1995-96' . 1996-97 on 7 sunflower (Helianthus anmaus L.)
genotypes for its tolerance to salinity under field conditions on sa. Vertisols (with a salinity gradient ranging from
1.1 to 20 dS/m) of Tungabhadra Project area. The seed yield of sunflower genotypes was correlated.with time weighted
mean salinity to compute yield maxima, threshold salinity and slope. 'CO 2', 'PAC 36' and 'PKVSH 27' sunflower
performed better than other genotypes at higher salinity levels (> 8 dS/m). The genotypes 'PAC 308', 'CO 4' and 'EC
68414' which were promising under marginally saline conditions (4-8 dS/m) suffered at higher salinity (> 8 dS/m).
There was high correlation between the performance of genotypes under saline conditions in the field and laboratory.
