Wheat seed demand assessment assisted by genotyping in Ethiopia

Moti Jaleta Kindie Tesfaye Olaf Erenstein (2023, [Artículo])

This study examines the extent to which wheat varieties supplied by the formal seed system align with the varieties demanded and used by farmers in Ethiopia. The framework of stated and revealed preferences drawn from the consumer preference theory is used to analyze farmer demand for different wheat varieties. We used official data from the formal seed sector and representative survey data from wheat farm households in Ethiopia. The survey data allow to contrast the farmer reported varietal use with genotyping by sequencing (also known as DNA fingerprinting). Farmers' reliance on informal seed sources and own saved seed, among others, contributes to the misidentification of the varieties they grow. Consequently, farmers are likely to misinform the formal seed demand assessment leading to either an over- or underestimation of actual seed demand for specific wheat varieties. Genotyping by sequencing, as opposed to farmer reports, established the persistence of old varieties. This also implies vulnerability of wheat production to disease dynamics depending on the longevity of disease resistance by the variety in use. Apart from narrowing the gap between the actual and stated demand and ensuring timely replacement of wheat varieties, genotyping-assisted estimates can save seed carry-over cost. Genotyping by sequencing is increasingly used as the new benchmark and gold standard for identifying and tracking the adoption of crop varieties. The technique has potential to enhance the performance of the seed sector through effective planning that can optimize resource commitments and accelerate the rate of varietal replacement.

¿Por qué revalorizar los nances y sus variedades de colores?

Diana Elidé Burgos Lugo MARIA TERESA CASTILLO BURGUETE DANIELA ALEJANDRA MARTINEZ NATAREN (2023, [Artículo])

Los nances, frutales ancestrales con distribución desde el sureste mexicano hasta Sudamérica, están dejando de cultivarse y poco se conoce sobre sus variedades con frutos de colores, debido a los cambios en los hábitos de consumo y estilo de vida de las personas. El manejo tradicional de los nances se realiza en huertos familiares y parcelas de cultivo, cuyos frutos son recolectados, en ocasiones, con la participación familiar. Las formas de uso culinario de los nances, son parte de la cultura maya y ofrecen beneficios para la salud y la economía de los habitantes de comunidades rurales. Invitamos a conocer y apreciar los frutos de estos árboles que todavía están a nuestro alcance.
