Assessment of on-farm conservation of dryland agrobiodiversity and its impact on rural livelihoods in the Fertile Crescent
The Fertile Crescent encompasses a mega-center of diversity of crops and livestock of global importance. The
International Center for Agricultural Research in the Dry Areas (ICARDA) coordinated a 5-year regional project
funded ...
Estimation of (co)variance components, genetic parameters, and genetic trends of growth traits in community-based breeding programs of Bonga sheep
Community-based sheep breeding programs (CBBPs) have been adopted strategically to improve Bonga
sheep, the most popular sheep breed in Ethiopia. The present study was undertaken to estimate genetic
parameters and genetic ...
Genetic structure, diversity, and allelic richness in composite collection and reference set in chickpea (Cicer arietinum L.)
Background: Plant genetic resources (PGR) are the basic raw materials for future genetic progress and an insurance against unforeseen threats to agricultural production. An extensive characterization of PGR provides an ...
Genetic Variation Controlling Wrinkled Seed Phenotypes in Pisum: How Lucky Was Mendel?
One of the traits studied by Mendel in pea (Pisum sativum L.) was the wrinkled-seeded phenotype, and the molecular basis for a mutation underlying this phenotype was discovered in the 1990s. Although the starch-branching ...
Assessment of the suitability of Triticum turgidum accessions for incorporation into a durum wheat breeding program
Expanding the genetic basis of modern wheat cultivars may improve yield stability and increase grain yields under climatic changes, to feed the growing human population. The main objective of this study was to evaluate the ...
Diversity analysis of 80,000 wheat accessions reveals consequences and opportunities of selection footprints
Undomesticated wild species, crop wild relatives, and landraces represent sources of variation for wheat improvement to address challenges from climate change and the growing human population. Here, we study 56,342 ...
Yield gain due to fungicide application in varieties of winter wheat (Triticum aestivum) resistant and susceptible to leaf rust
In three independent experiments in Turkey and Kazakhstan, winter wheat germplasm with variable degrees of resistance to leaf rust was subjected to fungicide protection. The yield loss of genotypes susceptible to leaf rust ...
Effects of genotype and simulated rainfall on the morphological characteristics, chemical composition and rumen degradation of the straw fractions of barley plants
Experiments comparing the nutritive value of cereal straws from different genotypes are often complicated by the difference in plant height which is affected by genotype and the amount of rainfall. Two experiments were ...
Is long-term protection useful for the regeneration of disturbed plant communities in dry areas?
In dry areas, natural plant communities are mainly affected by climatic stress and human disturbances – overgrazing, ploughing and biomass harvesting – that accelerate their degradation. Management techniques, including ...
Efficiency of spatial methods in yield trials in lentil (Lens culinaris ssp. culinaris)
Incomplete block (IB) analysis of lentil yield trials in lattice block designs substantially reduced experimental error variability compared to randomized complete block (RCB) analysis. Spatial variability, which may exist ...
