Abstract:
A population of soft wheat which lives naturally on the edges of saline Ain Malilah’s Sebkha, located to the southeast of Qasantina from the east of Algeria, and four varieties i.e. HD1220, ARZ, AS and ANF, to evaluate their performance under several abiotic stresses conditions, and to study their response to fertilization, based on some phenological, morphological, chemical characteristics such as: Life cycle (from cultivation until the appearance of 1/4 spikes), germination potentiality, tellering, leaf area, total chlorophyll content, relative water content, carbohydrates content. The studied population (SBR) was characterized by some morphological traits such as: Short length of plants, reduced leaf area, no awn, very late life cycle which record delayed up to 35, 28, 19, and 17 compared to ARZ, HD1220, ANF and AS respectively. The population and the studied varieties showed significant variation in their response to abiotic stress conditions. Relative water content in leaves, leaf area and plant high declined significantly under severe water stress (25% of field capacity). The studied population showed high adaptability and low fertilizer requirements under conditions of salt stress and fertilization. The results recommend that the SBR population should be used in future selection programs, to improve some characteristics of wheat varieties to face various environmental stresses.
Key words: Soft wheat, Ain Malilah Sebkha, salty stress, water stress, fertilization.
