Sheep breeding schemes utilising artificial insemination; large-scale simulation with a complex breeding goal

Animal, 2011
Alternative Norwegian sheep breeding schemes were evaluated by stochastic simulation of a breeding population with about 120 000 ewes, considering the gain for an aggregate genotype including nine traits and also the rate of inbreeding. The schemes were:

In situ assessment of Jatropha curcas germplasm under tropical dry forest conditions in Manabí-Ecuador

Revista Facultad Nacional de Agronomía Medellín, 2020
Jatropha germplasm accessions need an assessment of their traits to evaluate the nature and magnitude of the genetic variability among accessions. The objective of this research was to evaluate the phenotypic behavior of 130 Jatropha curcas L. (Jatropha)

Assessment of Efficiency of Breeding Methods in Accelerating Genetic Gain in Rice

Agronomy
The pedigree, bulk, and single-seed descent-based rapid generation advance methods are commonly practiced breeding methods in rice. But the efficiency of these breeding methods in enhancing genetic gain has not been investigated yet.
