PERENNIAL GRAINS FOR AFRICA: POSSIBILITY OR PIPEDREAM? [PDF]

Experimental Agriculture, 2018
SUMMARYPerennial grain crops have been proposed as a transformative approach to agriculture. Replacing annual staple crops with perennialized growth types of the same crops could provide environmental services, improve labour efficiency and weather resilience, reduce seed costs and produce livestock fodder or fuelwood production.

Prospects for Developing Perennial Grain Crops [PDF]

BioScience, 2006
Abstract Perennial plants, growing in mixtures, make up most of the world's natural terrestrial biomes. In contrast, monocultures of annual crops are sown on more than two-thirds of global cropland. Grain and oilseed crops are the foundation of the human diet, but to date there are no perennial species that produce adequate grain harvests.

Agronomic Evaluation and Molecular Cytogenetic Characterization of Triticum aestivum × Thinopyrum spp. Derivative Breeding Lines Presenting Perennial Growth Habits

Plants, 2023
The transition from annual to perennial growth habits can contribute to increased sustainability and diversification of staple cropping systems like those based on annual wheat. Amphiploids between Triticum aestivum and Thinopyrum spp.

Agronomic Performance of Perennial Grain Genotypes in the Palouse Region of the Pacific Northwest, USA

Frontiers in Sustainable Food Systems, 2019
Annual plants are currently the dominant growth habit for grain production systems but often create agroecosystems with negative environmental consequences.

The use of wheatgrass (Thinopyrum intermedium) in breeding

Вавиловский журнал генетики и селекции, 2022
Wheatgrass (Th. intermedium) has been traditionally used in wheat breeding for obtaining wheat-wheatgrass hybrids and varieties with introgressions of new genes for economically valuable traits.

Comparative Analysis of Early Life Stage Traits in Annual and Perennial Phaseolus Crops and Their Wild Relatives

Frontiers in Plant Science, 2020
Herbaceous perennial species are receiving increased attention for their potential to provide both edible products and ecosystem services in agricultural systems. Many legumes (Fabaceae Lindl.) are of special interest due to nitrogen fixation carried out

The effect of perennial forage crop on grain yields in submontane regions

Plant, Soil and Environment, 2002
The structure of crop production (areas under crops, crop yields, fertilization) in 15 agricultural farms in potato-production and mountain regions of the Czech Republic was analyzed to evaluate the relations between NPK fertilization level, percentage ...

Abiotic and biotic context dependency of perennial crop yield.

PLoS ONE, 2020
Perennial crops in agricultural systems can increase sustainability and the magnitude of ecosystem services, but yield may depend upon biotic context, including soil mutualists, pathogens and cropping diversity.
