Abstract
The International Wheat Improvement Network (IWIN), an alliance of national agricultural research systems (NARSs), International Maize and Wheat Improvement Center (CIMMYT), International Center for Agricultural Research in the Dry Areas (ICARDA), and advanced research institutes (ARIs), continues to deploy cutting-edge science alongside practical multi-disciplinary applications, resulting in the development of germplasm that has made major contributions during the Green Revolution. The continuous supply of improved germplasm for nearly half a century has also enabled developing countries to have a sustained increase of wheat production and productivity and thereby improving food security and farmers’ livelihoods. Wheat production levels have increased from 235 million tons in 1961 to 691 million tons in 2012. Yet, global food consumption has exceeded production for 6 of the last 11 years (2004–2010), and food reserves are now ‘dangerously low,’ particularly for staple grains such as wheat and maize. Changing diets, urbanization, and other factors mean that demand for wheat is likely to only multiply further, and therefore wheat yields must increase from the current global average of 3 t per hectare. According to some estimates, the global wheat production must increase at least by 1.6 % annually to meet a projected yearly wheat demand of 760 million tons by 2020. In the year 2050, the world population is estimated to be nine billion and the demand for wheat reaches more than 900 million tons. Fulfilling this demand is very challenging with the current scenario of climate change, increasing drought/water shortage, soil degradation, reduced supply & increasing cost of fertilizers, increasing demand for bio-fuel, and emergence of new virulent diseases and pests. This paper presents a review and insight about the past and current contributions of IWIN, breeding progresses and genetic gains, and its future role in offsetting the major global challenges of wheat production.

The international winter wheat improvement program (IWWIP), an alliance between Turkey–CIMMYT–ICARDA, has distributed improved germplasm to different National Agricultural Research Systems (NARS) partners through international nurseries and yield trials for the last 25 years. This study was carried out in order to determine the rate of breeding progress for yield and yield related traits at IWWIP using data of the international winter wheat yield trials (IWWYT), IWWYT 1–13, collected from 1997 t...

The recent emergence of wheat stem rust race Ug99 (TTKSK) and related strains threaten Ethiopian as well as world wheat production because they overcome widely used resistance genes that had been effective for many years. The major cause which aggravates the ineffectiveness of Ethiopian wheat varieties against stem rust is the narrow genetic base on which the breeding for resistance has been founded, however, little is known about the resistance genotypes of Ethiopian durum wheat varieties and t...

Genetic improvement to develop varieties with high yield potential and resistance/tolerance to abiotic and biotic stresses with acceptable end use qualities is the most viable and environment friendly option to increase wheat yield in a sustainable fashion. In vitro haploid production followed by chromosome doubling greatly enhances the production of complete homozygous wheat lines in a single generation and increases the precision and efficiency of selection process in wheat breeding. It also e...

The Global Wheat Program of the International Maize and Wheat Improvement Center (CIMMYT) develops and distributes improved germplasm targeted toward various wheat growing regions of developing world. The objective of our study was to quantify the genetic yield gains in CIMMYT’s spring bread wheat (Triticum aestivum L.) in the Elite Spring Wheat Yield Trial (ESWYT) distributed over the past 15 yr (1995–2009) as determined by the performance of entries across 919 environments in 69 countries.

Conservation agriculture (CA) has been proposed as an adapted set of management principles that assures a more sustainable agricultural production. It combines the following basic principles: (1) reduction in tillage, (2) retention of adequate levels of crop residues and soil surface cover, (3) use of crop rotations. These CA principles are applicable to a wide range of crop production systems. However, the application of CA will be different in different situations. Specific and compatible mana...

An analysis of over 20,000 historical African maize trials suggests the crop will better cope with climate change under rain-fed management. For a 1 °C temperature rise, optimal rain-fed conditions would mean 65% of maize-growing areas in Africa would be likely to experience yield losses, compared with 100% under drought conditions.

To investigate the influence of exogenous paclobutrazol (PBZ) application on the natural cold acclimation of Ligustrum lucidum, 1-year-old L. lucidum seedlings were conducted with PBZ at four concentrations (0, 100, 300, and 500 mg L−1) from September to December 2016, and leaves were collected to measure physiological and biochemical parameters. Results showed that 500 mg L−1 was the optimum concentration, which led to stronger freezing tolerance during natural cold acclimation. The enhanced fr...

Cytoskeleton plays a vital role in stress tolerance; however, involvement of intermediate filaments (IFs) in such a response remains elusive in crop plants. This study provides clear evidence about the unique involvement of IFs in cellular protection against abiotic stress in rice. Transcript abundance of Oryza sativa intermediate filament (OsIF) encoding gene showed 2–10 fold up-regulation under different abiotic stress. Overexpression of OsIF in transgenic rice enhanced tolerance to salinity a...

Summary Melatonin modulates the functional activation of antioxidative enzymes to maintain the oxidant–antioxidant balance in the physiological system. Melatonin administration via subcutaneous injection increases endogenous melatonin concentration that has been used to modulate the immune function in rodents and reproductive activity in small ruminant like goats. However, to date, no report exist which could suggest the effect of corn seed supplementation on the endogenous melatonin concentrati...

In recent decades, the scientific, development, and farm communities have contributed to substantial gains in crop productivity, including in many less developed countries (LDCs) ( 1 ), yet current yield trends and agri-food systems are inadequate to match projected demand ( 2 ). Addressing transnational crop challenges will require refinement of research infrastructure and better leverage of global expertise and technologies. Drawing on lessons learned from international collaboration in wheat,...

Drought is the major limiting abiotic factor for plant growth in Seasonally Tropical Dry Forests (STDF), affecting the leaf construction cost (LCC), and the strategies of carbon investment. This work aimed to investigate the influence of rainfall in LCC of three species with different growth forms (Cenostigma pyramidale (tree), Hyptis suaveolens (herbaceous) and Sida galheirensis (sub-shrub)) during three consecutive rainy seasons (2013–2015) in a STDF, and how LCC is related to environmental an...

Background: Opportunities to use data and information to address challenges in international agricultural research and development are expanding rapidly. The use of agricultural trial and evaluation data has enormous potential to improve crops and management practices. However, for a number of reasons, this potential has yet to be realized. This paper reports on the experience of the AgTrials initiative, an effort to build an online database of agricultural trials applying principles of interope...

A transnational approach to plant science is required to address global challenges such as food security and climate change. Action from the plant, crop and agricultural science communities will be required to meet these challenges. Islands of knowledge (e.g. crop, discipline, scale, environment, organization) need to be better integrated. Mapping is needed to identify gaps and make connections between these islands. Translational research, spanning from the molecular to farm scale, should be th...

Over the last few years, a boom has been witnessed in the area of soil ecology which has produced numerous data on interactions between plant and rhizospheric microbes. The plant-microbe interactions in the rhizospheric niche have proved to be crucial for the advancement of sustainable farming practices which decrease the usage of chemical fertilizers and pesticides. Root exudates are substances released by plant roots that show a significant role in mediating the plant-microbe interactions in s...
