There is a need for dwarf and narrow lobed-leaves rapeseed cultivars to reduce transpiration under drought prone areas. A dwarf mutant line ‘H2M-1’ and a mutant with reduced lobed-leaf ‘H2M-2’ were developed. To exploit these mutated traits properly in an effective breeding program, one should understand their mode of inheritance. There are conflic...

Combining phenotypic and genotypic germplasm characterization is a key to efficient and successful safflower (Carthamus tinctorius L.) breeding program by identifying valuable and confirmed parents. This study aimed to investigate and use appropriate statistical methods for such a characterization, and to identify potential genetic pools in safflow...

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...

Agronomic potential of traditional sunflower spring varieties is low because its flowering and grain filling are often exposed to mid and end-season drought. To overcome this, new breeding strategy consisted of selecting varieties tolerant to winter cold in order to shift to autumn or early winter planting. Nowadays, ‘Ichraq’ is the only one regist...

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...

There is limited variability within rapeseed germplasm in Morocco. Induced mutation was recently used to generate novel genetic variability and develop mutant lines combining desirable traits. In this context, nine promising advanced rapeseed M2 mutant lines and the wild‐type variety “INRA‐CZH2” were evaluated for their seed oil content, fatty acid...

Induced mutation may be an effective alternative to get a novel genetic variability that might not be found in natural germplasm. Seeds of Brassica napus L. (variety ‘INRA-CZH2’) were treated by Ethyl Methane Sulphonate (EMS), with 1, 1.2, 1.4 and 1.6% doses during 6, 7 and 14 hours, and were planted to obtain the M1 plants and then the M2 plants....

Genetic variability is a prerequisite for any plant breeding program, and mutagenesis is a proven way of creating new variation within a crop germplasm. Novel genetic variability in rapeseed was induced by gamma rays, Ethyl Methane Sulphonate (EMS) and combined mutagen treatment, using various doses and concentrations. The objective was to evaluate...

Rapeseed ( Brassica napus L.) crop has a high yield potential in Morocco, particularly in the Gharb region. However, this area is subjected to relatively frequent water floods usually accompanied with soil waterlogging, which is harmful for the crop. This study aimed to assess the behavior and productivity of four Moroccan varieties under waterlogg...
