On-farm assessment of yield and quality traits in durum wheat

Facundo Tabbita Iván Ortíz-Monasterios Francisco Javier Pinera-Chavez Maria Itria Ibba Carlos Guzman (2023, [Artículo])

BACKGROUND: Durum wheat is key source of calories and nutrients for many regions of the world. Demand for it is predicted to increase. Further efforts are therefore needed to develop new cultivars adapted to different future scenarios. Developing a novel cultivar takes, on average, 10 years and advanced lines are tested during the process, in general, under standardized conditions. Although evaluating candidate genotypes for commercial release under different on-farm conditions is a strategy that is strongly recommended, its application for durum wheat and particularly for quality traits has been limited. This study evaluated the grain yield and quality performance of eight different genotypes across five contrasting farmers’ fields over two seasons. Combining different analysis strategies, the most outstanding and stable genotypes were identified. RESULTS: The analyses revealed that some traits were mainly explained by the genotype effect (thousand kernel weight, flour sodium dodecyl sulfate sedimentation volume, and flour yellowness), others by the management practices (yield and grain protein content), and others (test weight) by the year effect. In general, yield showed the highest range of variation across genotypes, management practices, and years and test weight the narrowest range. Flour yellowness was the most stable trait across management conditions, while yield-related traits were the most unstable. We also determined the most representative and discriminative field conditions, which is a beneficial strategy when breeders are constrained in their ability to develop multi-environment experiments. CONCLUSIONS: We concluded that assessing genotypes in different farming systems is a valid and complementary strategy for on-station trials for determining the performance of future commercial cultivars in heterogeneous environments to improve the breeding process and resources.

Heteranthera yucatana (Pontederiaceae), una especie pequeña, hermosa, endémica …. y amenazada

GERMAN CARNEVALI FERNANDEZ CONCHA RODRIGO STEFANO DUNO Ivón Mercedes Ramírez Morillo José Ramón Grande Allende Yeni Celeste Barrios José Luis Tapia Muñoz (2022, [Artículo])

En el año 2000, personal del Herbario CICY detectó en las cercanías de la Zona Arqueológica de Xcambó, al norte del estado de Yucatán, una pequeña planta semi-acuática que llamó la atención de los colectores. Justo a finales del año 2019, unos meses antes del inicio de la pandemia, salimos nuevamente al campo y la volvimos a conseguir. Esta vez nos cuestionamos su identidad, y tras algunas semanas de búsqueda e investigación, comprobamos que se trataba de un nuevo taxón. Este año, después de muchos ires y venires, ha sido establecida como una especie nueva para la ciencia: Heteranthera yucatana. Esta especie se caracteriza entre otras cosas por su reducido tamaño, su distribución limitada al norte del estado de Yucatán y su categoría de riesgo: “En Peligro”.
