Genetic analysis of vegetative ground cover rate in winter wheat using digital imaging
Vegetative vigour is an important physiological trait and selection for greater seedling vigour is a goal of breeding programs, especially in rain-fed regions. This study aimed to identify the genetic variation of early ...
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 ...
Indirect selection for grain yield in spring bread wheat in diverse nurseries worldwide using parameters locally determined in north-west Mexico
The relationships of normalized water index three (NWI-3) and canopy temperature (CT) with grain yield in north-west Mexico were determined in a set of wheat lines planted in multi-location yield trials. Advanced wheat ...
Detection of two major grain yield QTL in bread wheat (Triticum aestivum L.) under heat, drought and high yield potential environments
A large proportion of the worlds? wheat growing regions suffers water and/or heat stress at some stage during the crop growth cycle. With few exceptions, there has been no utilisation of managed environments to screen ...
