Germination Stage Screening of Mutants of Cowpea (Vigna unguiculata L. Walp) to Salinity Tolerance

To test the tolerance of cowpea mutants to salinity, wilds and were subjected 50, 100, 150, 200, 250 mM NaCl for salinity. Genotype salt concentration interaction significant. GxS explained mostly variation observed. More informative concentrations found in 50 (99.08) C100 (72.50) against 26.80 control environment. High had lowest germination rates. Seed rate genotypes decreased from 56.46 20.58 with a mean 36.28 variance 99.08. Despite strong correlations observed between indices, very weak ones AD STI, -0.02, -0.44, -0.7, -0.79 -0.84 respectively at 200 250. Mouride wild types most tolerant 43 % versus 48 551 Melakh Yacine. Six (6) more weakest checks performance which was 9th best performance.
