Genetic mapping of loci associated with yield and their components in black common bean (Phaseolus vulgaris L.) [PDF]

The Plant Genome, Volume 18, Issue 2, June 2025.
Abstract The increase in world population linked to climate change leads to the need to develop more productive and more adapted cultivars of food species. Quantitative trait loci (QTLs) mapping is a useful tool although, interaction between genotype and the environment is still a challenge.

Genotypic ranking and repeatability coefficient in elephant grass genotypes for biomass production for energy applications

Agrosystems, Geosciences &Environment, Volume 8, Issue 2, June 2025.
Abstract Energy demand has become a global bottleneck, and the search for alternative sources is intensifying worldwide. In this context, elephant grass emerges as an excellent alternative due to its high dry matter production capacity coupled with beneficial biomass quality, high fiber content, high C/N ratio, and high calorific value.
