Centrosema spp. es uno de los géneros más importantes dentro de las accesiones de leguminosas forrajeras en el área de impacto de suelos ácidos e infértiles del trópico. En estos materiales se presenta un alto porcentaje de semillas duras, que aún al proporcionar las condiciones óptimas para que...

En cinco muestras de semillas de B. dictyoneura cosechadas en la misma época en Colombia, Panamá y Costa Rica, se evaluó el efecto de tres niveles de calor seco (ambiente, 40 y 60°C) y tres tiempos de exposición (0, 72 y 240 h) aplicados a uno y tres meses poscosecha en espiguillas completas o es...

Domestication represents a unique opportunity to study the evolutionary process. The elimination of seed dispersal traits was a key step in the evolution of cereal crops under domestication. Here, we show that ObSH3, a YABBY transcription factor, is required for the development of the seed abscis...

Over the past three decades, more than 40 banana cultivars have been introduced in eastern and southern Africa for evaluation and dissemination to smallholder farmers facing banana productivity challenges. This study analyses the seed systems used to avail the genotypes to the target users, discu...

Published studies to date have suggested that seed-yam (Dioscorea rotundata) production in Nigeria using minisett (∼0.025 kg) technology or an adapted form of the technology using larger setts (0.08 to 0.1 kg) was not profitable. But these studies were often conducted under artificial conditions ...

High seed quality is a critical component for realising yield potential. For smallholder cowpea farmers in northern Nigeria the informal seed system is a major supplier of genetically high-quality seed, but the physiological quality of farmers’ produced seed remains unknown. The project “Promotin...

Phytate is an important antinutritional component of legume seeds, which chelates minerals that are essential to the human diet such as iron and zinc. Phytate levels are often correlated with total seed phosphorus (P). The objective of this research was to evaluate quantitative trait loci (QTL) f...
