EffEctivE sElEction critEria for assEssing drought strEss tolErancE in durum whEat (TriTicum durum dEsf.)
Drought is a wide-spread problem seriously influencing durum wheat (Triticum durum Desf.) production and quality, but development of resistant cultivars is hampered by the lack of effective selection criteria. The objective of this study was to evaluate the ability of several selection indices to identify drought resistance cultivars under a variety of environmental conditions. Twenty four duru...
متن کاملPhenotypic Diversity of Tunisian Durum Wheat Landraces
Tunisia is considered as a diversification centre of durum wheat (Triticum durum Desf.) and barely (Hordeum vulgare). It is characterised by large genetic diversity; however, several genotypes are in the process of disappearance. The safeguard and rehabilitatation of this genetic inheritance requires genetic characterisation, evaluation and in-situ and ex-situ conservation. In this context, a l...
متن کاملSome Physiological and Biochemical Effects of NaCl Salinity on Durum Wheat (Triticum durum Desf.)
The main objective of this study was to examine the effects of NaCl on the leaf growth and some physiological and biochemical characteristics of an Algerian durum wheat (var. Waha) landrace. NaCl (150 mM), as compared to control plants, significantly reduced all the leaf-growth parameters as leaf area (33%), leaf dry weight (41%) and leaf fresh weight (32%), but did not induce any change in the...
متن کاملSecretory Phospholipases A2 in Durum Wheat (Triticum durum Desf.): Gene Expression, Enzymatic Activity, and Relation to Drought Stress Adaptation
Phospholipases A2 (PLA2s) are known to mediate signaling cascades during plant growth and development, as well as biotic and abiotic stress responses. In this context, the present study provides extensive characterization of specific PLA2s in durum wheat, and assesses their involvement in durum wheat response to drought stress. In durum wheat leaves, four full-length expressed sequences encodin...
متن کاملSNP-based association analysis for seedling traits in durum wheat (Triticum turgidum L. durum (Desf.))
In the present study, 150 accessions of worldwide originated durum wheat germplasm (Triticum turgidum spp. durum) were observed for major seedling traits and their growth. The accessions were evaluated for major seedling traits under controlled conditions of hydroponics at the 13th, 20th, 27th and 34th day-after germination. Biomass traits were measured at the 34th day-after germination. Correl...
