Phenotyping for breeding and physiological pre-breeding
Spectral water indices for assessing yield in elite bread wheat genotypes under well-irrigated, water-stressed, and high-temperature conditions
The objective of the present work was to determine the relationship between spectral reflectance indices (SRI) and yield in spring wheat (Triticum aestivum L.) in NW Mexico in three environments (irrigated, water-stress, ...
Genetic yield gains and changes in associated traits of CIMMYT spring bread wheat in a 'Historic' set representing 30 years of breeding
The genetic yield progress of 26 spring wheat (Triticum aestivum L.) advanced lines released by the International Maize and Wheat Improvement Centre (CIMMYT) in the period from 1977 to 2008 was evaluated in the selection ...
The yield correlations of selectable physiological traits in a population of advanced spring wheat lines grown in warm and drought environments
Genetic progress in yield will increase if more traits conferring better agronomic and physiological performance are brought together in the same variety through full exploitation of genotyping and phenotyping techniques ...
Phenotyping transgenic wheat for drought resistance
Realistic experimental protocols to screen for drought adaptation in controlled conditions are crucial if high throughput phenotyping is to be used for the identification of high performance lines, and is especially important ...
Genetic yield gains of the CIMMYT international semi-arid wheat yield trials from 1994 to 2010
Genetic progress for yield has been assessed globally in the semi-arid wheat yield trials (SAWYTs) of the International Maize and Wheat Improvement Center (CIMMYT) over a 17-yr period. Grain yield expressed as a percentage ...
Genetic dissection of grain yield and physical grain quality in bread wheat (Triticum aestivum L.) under water-limited environments
In the water-limited bread wheat production environment of southern Australia, large advances in grain yield have previously been achieved through the introduction and improved understanding of agronomic traits controlled ...
Quantifying genetic effects of ground cover on soil water evaporation using digital imaging
Rapid development of leaf area and/or aboveground biomass has the potential to improve water harvest of rain fed wheat in Mediterranean-type environments through reduced soil evaporation. However, quantitative relationships ...
Heat and drought adaptive QTL in a wheat population designed to minimize confounding agronomic effects
A restricted range in height and phenology of the elite Seri/Babax recombinant inbred line (RIL) population makes it ideal for physiological and genetic studies. Previous research has shown differential expression for yield ...
