Genetic Variability and Phenotypic Correlations Study among Grain Quality Traits and Mineral Elements Concentrations in Colored and Non-Colored Rice (<i>Oryza sativa</i> L.) Open
Twenty-four rice genotypes were examined to assess genetic variability, heritability, and correlations for seven-grain quality traits, eight nutritional elements, and protein. ANOVA revealed significant differences for the quality traits s…

Comparative Genetic Diversity Assessment and Marker–Trait Association Using Two DNA Marker Systems in Rice (Oryza sativa L.) Open
In this paper, the genetic diversities of 12 rice genotypes (Oryza sativa L.), representing Indica, Japonica, and Indica–Japonica varieties, were assessed using twelve ISSR and five SSR markers. In addition, the rice genotypes were evaluat…

Conventional Breeding and Molecular Markers for Blast Disease Resistance in Rice (Oryza sativa L.) Open
Monogenic lines, which carried 23 genes for blast resistance were tested and used donors to transfer resistance genes by crossing method. The results under blast nursery revealed that 9 genes from 23 genes were susceptible to highly suscep…

Rice (Oryza sativa L.) Breeding among Hassawi Landrace and Egyptian Genotypes for Stem Borer (Chilo agamemnon Bles.) Resistance and Related Quantitative Traits Open
Rice stem borer (Chilo agamemnon Bles.) is a primary insect pest of rice and is a major limiting factor to rice production. Breeding for insect-resistant crop varieties has been an economic way of integrated pest management (IPM) as it off…

Isolation, Morphotyping, Molecular Characterization and Prevalence of Free-Living Amoebae from Different Water sources in Makkah city, Saudi Arabia Open
Free-living amoebae (FLA) are protozoa that can be found in a wide range of habitats around the world. Some species have been found to be pathogenic to humans in addition to their normal distribution. There is no research on the prevalence…

Molecular identification of blast resistance genes in rice genotypes using gene-specific markers Open
Molecular identification of major blast resistance (R) genes in rice was performed in a group of 10 rice (Oryza sativa) genotypes from Egypt and Saudi Arabia using six DNA markers (T8042, NSB, YL153/YL154, RM3843, RM3330, and z4794) belong…

Improvement of Blast Resistance and Yield Productivity in Rice (Oryza sativa L.) Using Tissue Culture and Combining Ability Open
Background and Objective: Blast disease is one of the major pathogens affecting crop productivity.Breeding for resistant is economic way to produce resistant variety and tissue culture used as a tool to decrease the period of breeding prog…

IMPORTED MALARIA TO MAKKAH DISTRICT, SAUDI ARABIA: IS THERE ANY RISK OF LOCAL TRANSMISSION? Open
In Makkah, Saudi Arabia, there is an impending risk of imported malaria.This risk comes from the fact that millions of people, in majority from tropical and subtropical countries where malaria is endemic, visit the country to perform Hajj …
