Differential analysis of five quinoa (Chenopodium quinoa W.‎) genotypes under different salt stresses in a controlled environment

Soil salinization is a global problem which restricts the choice of crops for cultivation.‎ Management and reclamation of saline soils using costly and time consuming methods such as installation of drainage systems is beyond the reach of poor farmers.‎ Therefore, it is important to look for alternate crops which are more salt-tolerant.‎ One such crop is quinoa (Chenopodium quinoa W.‎), which has high nutritious value and capacity to grow in marginal conditions.‎ As crops vary in their tolerance to salinity, they need to be evaluated for different salinity conditions.‎ This study was conducted to evaluate 5 quinoa genotypes (ICBA-Q1, ICBA-Q2), ICBA-Q3, ICBA-Q4 and ICBA-Q5) for their salinity tolerance under four artificially induced salinity (5, 10, 15, 20 dSm-1) levels.‎ The parameters studied were rate of seed germination, plant height, dry biomass, nutritional content and grain yield.‎ The results indicate that salinity had an inhibitory effect on all parameters.‎ Out of 5 quinoa genotypes, ICBA-Q3 and ICBA-Q4 proved more salt-tolerant under saline conditions with regard to dry biomass and grain yield and nutritional contents.‎ Therefore these two genotypes are recommended to farmers for large-scale adaptation in the salt-affected areas of Ethiopia.‎
