Sesame (Sesamum indicum L.) is an oilseed, aromatic, and medicinal plant with seeds rich in phytochemicals showing many nutritional and medicinal properties. To satisfy the human nutritional needs and to improve the economic efficiency of this crop, the current trend is to increase both its seed yield and nutritional quality. In this context, we ev...

The interest of this work is to appreciate the plasticity of tolerance and adaptability to high temperatures by analyzing the production, growth, physiology and fruit quality traits of the plum variety ‘Angelino’ (Prunus salicina L.). The experiment was conducted in 2021 on fourteen-year-old trees under drip irrigation installed at National Institu...

Pomegranate trees are known for their ability to withstand drought conditions, but there is still much to learn about how water stress affects the lipobiochemical behavior of their seeds. This study aimed to investigate how sustained deficit irrigation (SDI-50), equivalent to 50% of crop evapotranspiration, influences pomegranate seed oil attribute...

Sesame (Sesamum indicum L.) is an ancient oilseed, aromatic, and medicinal crop widely used for its high-quality oil and seeds. The available genetic diversity in Morocco is too limited; thus, a mutagenesis breeding program was adopted. This study was carried out to evaluate the novel variability induced and observed in 11 M4 mutant lines and to es...

In the context of climate change and water scarcity, it is necessary to develop and use drought-resistant crops. Sesame (Sesamum indicum L.) is an oleaginous and aromatic plant with high nutritional value. It is a tropical crop, but it is also grown in arid and semi-arid environments such as Morocco. Our aim is to evaluate (in two separate experime...

Sesame ( Sesamum indicum L.) is one of the most recommended oil crops due to its nutritional and medicinal properties. It is a tropical and subtropical plant; however, it is also cultivated in arid and semi-arid regions, including Morocco. Nevertheless, the sesame crop in this country faces many constraints and challenges that restrict its producti...

Sesame is an ancient oilseed plant with important agronomic, therapeutic, and industrial properties. Moroccan sesame is characterized by low productivity due to wild traits. To overwork, such wild characters, genetic improvement of plants is necessary. However, in Morocco, the existing genetic diversity is limited. Thus, chemical mutagenesis, using...

Sesame (Sesamum indicum L.) is a tropical oilseed crop that is also cultivated in arid and semi-arid environments, where drought occurs frequently. The objective of this study was to assess the performance of some sesame mutants, developed by our team through EMS-mutagenesis in 2020, under well-watered conditions and restricted irrigation by analyz...

Sesame seed represents a reservoir of nutritional components with many medicinal properties. With the current trend to increase both seed yield and nutritional quality, the cultivation of new high-quality sesame varieties is a necessity to improve human health and promote the economic efficiency of this crop. However, research efforts for the devel...

Sesame (Sesamum indicum L.) is an oilseed tropical crop affected by climate change and drought stress. The objective of this study was to evaluate the performance of 13 sesame mutants under full irrigation conditions and stress hydric. The morphological, physiological, and agronomic traits were analyzed. The experience was in pots according to a ra...

In the context of climate change and water scarcity, there is a need to develop and use drought-tolerant sesame cultivars. This study was conducted to evaluate the response of 13 sesame genotypes, including 11 mutants and their wild-types, to drought during germination and early seedling growth. Moderate and severe drought stress was simulated by a...

Sesame (Sesamum indicum L.) is an ancient oilseed crop with important agronomic, therapeutic, and industrial properties. However, in Morocco, the existing genetic diversity is quite limited. Thus, chemical mutagenesis, using ethyl methane sul-fonate (EMS), was applied to induce novel genetic variability. Seeds of two sesame genotypes were treated u...
