TLDR
Breeders are asked to blend together all knowledge on the traits sustaining yield under drought and to accumulate the most effective QTLs and/or transgenes into elite genotypes without detrimental effects on yield potential, which will lead to new cultivars with high yield potential and high yield stability, that will result in superior performance in dry environments.About:

Dissertation
Improving waterlogging tolerance in barley with molecular and physiological markers
TL;DR: The formation of aerenchyma is one of the most crucial adaptive traits for waterlogging tolerance in wetland species such as rice and can be effectively used for further fine mapping, QTL positional cloning, and marker assisted selection.

Inter-cultivar variability in the functional and biomass response of garlic (Allium sativum L.) to water availability
TL;DR: Variability in the functional response of garlic to well-watered and water deficit conditions and its relationship with biomass components was analysed in five garlic cultivars and variability conformed to different adaptive strategies with regards to the plant water economy.
Journal ArticleDOI
Genetic Variability in Yield and Its Attributes of some Peanut (Arachis hypogaea L.) Genotypes under Different Water Regimes
TL;DR: The results indicated existence of moderate genetic variability accompanied with high heritability and high GAM among the studied traits; days to maturity, shelling %, pod yield/plant, seed yield/ plant and oil content under stress conditions.

Productivity response to plant density in five Sorghum bicolor varieties in dry environments
Mostafa M. Rady,Ali A. A. Mekdad +1 more
TL;DR: The integrated V1×D3 found to be the best treatment generating highest ethanol (biofuel), yields and seed index over two studied seasons, and this integrated treatment is recommended for dry environments.

Stability Parameters for Comparing Varieties
S. A. Eberhart,W. A. Russell +1 more
TL;DR: The model, Yij = μ1 + β1Ij + δij, defines stability parameters that may be used to describe the performance of a variety over a series of environments to see whether genetic differences could be detected.

Understanding plant responses to drought — from genes to the whole plant
TL;DR: Attention is drawn to the perception and signalling processes (chemical and hydraulic) of water deficits, which are essential for a holistic understanding of plant resistance to stress, which is needed to improve crop management and breeding techniques.
Journal ArticleDOI
Plant responses to drought, salinity and extreme temperatures: towards genetic engineering for stress tolerance
TL;DR: The present review summarizes the recent advances in elucidating stress-response mechanisms and their biotechnological applications and examines the following aspects: regulatory controls, metabolite engineering, ion transport, antioxidants and detoxification, late embryogenesis abundant (LEA) and heat-shock proteins.

The analysis of adaptation in a plant-breeding programme
K.W. Finlay,G.N. Wilkinson +1 more
TL;DR: Varieties from particular geographic regions of the world showed a similarity in type of adaptation, which provides a useful basis for plant introduction and breeding.

Seed Banks and Molecular Maps: Unlocking Genetic Potential from the Wild
TL;DR: The tools of genome research may finally unleash the genetic potential of the authors' wild and cultivated germplasm resources for the benefit of society.
