Rosemary Murori

In collaboration with IRRI scientists and national partners, Rosemary applies conventional and modern molecular breeding strategies to develop breeding products with tolerance of major biotic and abiotic stresses, including excellent grain quality for irrigated and rainfed lowland rice in East and Southern Africa.

She is also involved in training farmers and researchers on seed production across all rice-producing areas in Tanzania and Kenya. Rosemary recognizes that, in addition to developing rice varieties that are resistant to biotic and abiotic stresses and that will enhance the resilience of farming systems, quality seed production and availability are a challenge.

Rosemary helps organize the annual regional rice breeders workshops.
