ABSTRACT
The study was performed with seven groundnut varieties/genotypes and F1s derived from
crossing in all possible combinations without reciprocal among the mentioned
varieties/genotypes. The objective was
to assess whether low Ca2+ content and Ca2+/Na+ ratio of leaf tissue or stem tissue determine salinity tolerance in terms of
economic yield (kernel yield) in groundnut. It revealed that the varieties, “Binachinabadam-6”, “Binachinabadam-5” and the F1 G2 × G3 were most tolerant
based on kernel yield under 8 dS/m and 10 dS/m salinity stresses. These two
tolerant varieties and the F1 also showed lower Ca2+ and Ca2+/Na+ ratios in leaf tissue, which indicated
lower Ca2+ and Ca2+/Na+ ratio of leaf tissue
determined salinity tolerance
in terms of kernel yield in Spanish type groundnut. These findings could be applied in future plant breeding applications
for screening salt tolerant Spanish type groundnut genotypes.
