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 ...
Comparison of rank-based stability statistics for grain yield in rainfed durum wheat
Several rank-based stability statistics are in use, but little information is available on their repeatability and accuracy. The main objective was to examine the repeatability, similarity and accuracy of the estimates of ...
Predicting resistance to stripe (yellow) rust (Puccinia striiformis) in wheat genetic resources using focused identification of germplasm strategy
Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is a major wheat disease that can inflict yield losses of up to 70% on susceptible varieties under favourable environmental conditions. The timely identification ...
Predictive Characterization for Seed Morphometric Traits for Genebank Accessions Using Genomic Selection
Seed traits of bread wheat, including the seed size that is considered to be associated with early vigor of the crop and end-use quality, are valuable to farmers and breeders. In this study, a collection of 789 bread wheat ...
Institutional and farm-level challenges limiting the diffusion of new varieties from public and CGIAR centers: The case of wheat in Morocco
Low adoption of agricultural technologies slows efforts to increase agricultural productivity and enhance rural livelihoods in developing countries. A large body of literature has sought explanations for the problem, but ...
Genetic Gains in Wheat Breeding and Its Role in Feeding the World
Wheat is the leading global food crop providing 19% of the daily calories and 21% of protein requirements for humans. The wheat production has increased from 220 million tons in 1961 to 750 million tons in 2018 with total ...
Exploring and Mobilizing the Gene Bank Biodiversity for Wheat Improvement
Identifying and mobilizing useful genetic variation from germplasm banks to breeding programs
is an important strategy for sustaining crop genetic improvement. The molecular
diversity of 1,423 spring bread wheat accessions ...
Chlorophyll Fluorescence Parameters and Drought Tolerance in a Mapping Population of Winter Bread Wheat in the Highlands of Irand
The usefulness of fluorescence parameters as drought tolerance selection criteria for winter bread wheat in the highlands of Iran was studied. A population of 142 recombinant inbred lines, derived from a cross between two ...
Genetic diversity analysis using DArTseq and SNP markers in populations of Aegilops species from Azerbaijan
Despite a large number of Aegilops L.
species and their diversity in Azerbaijan, a majority of
this genetic material has not been characterized at
molecular levels. The current study has implemented
DArTseq technology to ...
Are continued public sector and CGIAR investments on wheat crop improvement research justifiable? A Moroccan case
In Morocco, the adoption of recent improved wheat varieties is low, casting doubt on whether investments in wheat research are paying off. This paper generates estimates of the returns to the national and international ...
