To feed the several billion people living on this planet, the production of high-quality food must increase with reduced inputs, but this accomplishment will be particularly challenging in the face of global environmental change. Plant breeders need to focus on traits with the greatest potential to increase yield. Hence, new technologies must be developed to accelerate breeding through improving genotyping and phenotyping methods and by increasing the available genetic diversity in breeding… 

Breeding crops to feed 10 billion

Development of next-generation crops will be enabled by combining state-of-the-art technologies with speed breeding by using speed breeding to enable plant breeders to keep pace with a changing environment and ever-increasing human population.

Using Genomics to Adapt Crops to Climate Change

Rising food demand from a growing global population, combined with a changing climate, endangers global food security. Thus, there is a need to breed new varieties and increase the efficiency and


This overview of conventional breeding methods and contemporary genomics techniques, and their function in crop improvement, is addressed.

Are we ready for back-to-nature crop breeding?

Emerging Concepts and Strategies for Genomics and Breeding

Plant biotechnology and genetic engineering techniques would continue to play a pivotal role in making a crop widely adaptable to the changed climate and improving crop efficiencies in utilization of solar radiation, inorganic nitrogen, water and other inputs would render crops suitable for climate-resilient agriculture.

Feeding the extra billions: strategies to improve crops and enhance future food security

The importance of genetic engineering as an indispensable tool to generate high-yielding and stress-tolerant future crops is highlighted and selected examples of candidate genes that may be manipulated are identified so that current biological maxima in yield may be surpassed by comfortable margins.

Maize Breeding: From Domestication to Genomic Tools

Maize will continue to expand and diversify as an industrial resource and a feed and fuel crop in the near future. The United Nations estimate that in 2050 the global population will reach 9.7

An overview of the advantages of MAS and its most widely used applications in plant breeding, providing examples from cereal crops and ways in which the potential of MAS can be realized are suggested.

Phenotyping approaches for physiological breeding and gene discovery in wheat

PT breeding at CIMMYT includes characterisation of crossing block lines for stress adaptive mechanisms, strategic crossing among parents that encompass as many target traits as possible and early generation selection (EGS) of bulks for canopy temperature (CT).

Molecular Markers in a Commercial Breeding Program

This work built genotyping systems and information tools and developed marker assisted methodologies that increased the mean performance in elite breeding populations and evaluated the potential to enhance genetic gain for quantitative traits.

Use of crop models to understand genotype by environment interactions for drought in real-world and simulated plant breeding trials

Simulation models of plant processes capture the biological interactions between the sensing of signals at an organ level and the response of the plant at a biochemical level, which constrain the crop yields to only those that are biologically possible in the given set of environments.

Methods to produce marker‐free transgenic plants

In this review, transformation using markers not based on antibiotic or herbicide resistance genes, as well as different systems of marker gene deletion, are discussed.

Agricultural Research, Productivity, and Food Prices in the Long Run

A reinvestment in agricultural R&D is critical to ensuring sufficient food for the world in the coming decades, and long-run trends in global food commodity prices are driven by differential rates of growth in the supply and demand for food crops, feed, and livestock products.

Molecular Plant Breeding as the Foundation for 21st Century Crop Improvement1

The fundamental discoveries of Darwin and Mendel established the scientific basis for plant breeding and genetics at the turn of the 20th century. Similarly, the recent integration of advances in

Food Security: The Challenge of Feeding 9 Billion People

A multifaceted and linked global strategy is needed to ensure sustainable and equitable food security, different components of which are explored here.

Heterosis for Grain Yield and Other Agronomic Traits in Foxtail Millet

High level of heterosis for grain yield suggested that varietal crosses or other types of cultivars in which there exists a relatively high amount of heterozygosity would provide a significant yield benefit over nonhybrid cultivars.
