Genetic dissection on rice grain shape by the two-dimensional image analysis in one japonica × indica population consisting of recombinant inbred lines
(Springer, 2015)
Two-dimensional (2D) digital image analysis is
efficient for investigating the rice grain shape characters in
large genetic and breeding populations. In this study, we
used 2D image analysis to investigate seven ...
A hierarchical bayesian estimation model for multienvironment plant breeding trials in successive years
(Crop Science Society of America, 2016)
In agriculture and plant breeding, multienvironment trials over multiple years are conducted to evaluate and predict genotypic performance under different environmental conditions and to analyze, study, and interpret ...
QTL Mapping of Agronomic Waterlogging Tolerance Using Recombinant Inbred Lines Derived from Tropical Maize (Zea mays L) Germplasm
(Public Library of Science, 2015)
Waterlogging is an important abiotic stress constraint that causes significant yield losses in
maize grown throughout south and south-east Asia due to erratic rainfall patterns. The most
economic option to offset the ...
Unmanned aerial platform‑based multi‑spectral imaging for field phenotyping of maize
(BioMed Central, 2015)
Background: Recent developments in unmanned aerial platforms (UAP) have provided research opportunities in assessing land allocation and crop physiological traits, including response to abiotic and biotic stresses. UAP-based ...
Genome‑wide association analysis reveals new targets for carotenoid biofortification in maize
(Springer, 2015)
Key message Genome-wide association analysis in
CIMMYT’s association panel revealed new favorable
native genomic variations in/nearby important genes such
as hydroxylases and CCD1 that have potential for carotenoid
b ...
Linkage analysis and map construction in genetic populations of clonal F1 and double cross
(Genetics Society of America, 2015)
In this study, we considered four categories of molecular markers based on the number of
distinguishable alleles at the marker locus and the number of distinguishable genotypes in clonal F1
progenies. For two marker loci, ...
Response to S1 recurrent selection for resistance to two stem borers, Busseola fusca and Chilo partellus, in two tropical maize populations
(Springer, 2015)
Stem borers, Busseola fusca and Chilo partellus, are among the key devastating lepidopteran insect pests ofmaize causing grain yield losses.Recurrent
selection studies for stem borer resistance in maize are limited. ...
Physiological and Molecular Aspects of Tolerance to Environmental Constraints in Grain and Forage Legumes
(Molecular Diversity Preservation International, 2015)
Despite the agronomical and environmental advantages of the cultivation of legumes, their production is limited by various environmental constraints such as water or nutrient limitation, frost or heat stress and soil ...
Performance and grain yield stability of maize populations developed using marker-assisted recurrent selection and pedigree selection procedures
(Springer, 2016)
A marker-assisted recurrent selection (MARS) program was undertaken in sub-Saharan Africa to improve grain yield under drought-stress in 10 biparental tropical maize populations. The objectives of the present study were ...
Managing vulnerability to drought and enhancing livelihood resilience in sub-Saharan Africa: Technological, institutional and policy options
(Elsevier, 2014)
Agriculture and the economies of Sub-Saharan Africa (SSA) are highly sensitive to climatic variability. Drought, in particular, represents one of the most important natural factors contributing to malnutrition and famine ...
