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 yield drastically. With this view, an experiment was conducted to observe genotypic differences in agro-morphological, yield, biochemical responses salinity. Experimental variables consisted of five salt-tolerant genotypes (G 13, G 20-1, 9, 22, 20-2), one susceptible genotype 24) standard check variety (BARI ghom 25), assigned four levels salinity with electrical conductivities 0, 4, 8 12 dS m−1. Irrespective genotypes, stress significantly decreased attributes. However, maximum total tillers plant−1, effective number grains spike−1, grain plant−1 found salt tolerant 20-2, followed lowest observed salt-susceptible 24. The reduction percentage attributes were also 20-2 Results showed that highest amount proline, glycinebetaine, soluble sugar protein content minimum On other hand, hydrogen peroxide (H2O2) melondealdehyde (MDA) accumulation detected same Therefore, higher accumulations compatible solute reduce oxidative stress, provide yield.
