Abstrakt
The study on agronomic and genetic characteristics of rice has given us scope to select
varieties with desirable characteristics to mitigate various constraints. Rice (Oryza sativa) is the
staple food for half of the world's population. However, its production is hampered by a variety
of biological constraints. The Blast disease (Pyricularia oryzae) is an important rice disease, and
one of the most effective control methods is to use resistant varieties. Study areas in Morocco
include the Gharb plains. For all methods, cultural practises like soil levelling seem to be
important, but biological control is not widely adopted due to cost, efficacy, and climatic
conditions. The bibliographic synthesis was carried out in this context with the main goals of
contributing to a better understanding of rice cultivation in Morocco; to identify and characterise
the structure of the rice blast pathogen (Pyricularia oryzae), which will allow us to characterise
the effects of rice blast; and to research on the Gharb rice field, which resulted in resistant
varieties, which will potentially allow producers to have resistant varieties to overcome the
diseases. The introduction and development of new rice varieties with high agronomic and
socioeconomic value; the selection of lines with high yield, good grain quality, and precocity that
are adapted to Moroccan conditions; as well as the development of new lines from Moroccan
rice, are among the specific goals.
