Agro-Morphological, Yield and Biochemical Responses of Selected Wheat (Triticum aestivum L.) Genotypes to Salt Stress

Wheat is affected by various biotic and abiotic stresses, especially salinity, which reduces the growth and yield drastically. With this view, an experiment was conducted to observe genotypic differences in agro-morphological, yield, and biochemical responses to salinity. Experimental variables consisted of five salt-tolerant genotypes (G 13, G 20-1, G 9, G 22, G 20-2), one susceptible genotype (G 24) and one standard check variety (BARI ghom 25), which assigned to four levels of salinity with electrical conductivities 0, 4, 8 and 12 dS m−1. Irrespective of genotypes, salinity stress significantly decreased the yield and yield attributes. However, maximum total tillers plant−1, effective tillers plant−1, number of grains spike−1, and grain yield plant−1 was found in salt tolerant genotype G 20-2,…
