Analysis of Genotype X environment interactions for grain yield in durum wheat
Genotype x environment (GE) interactions are important sources of variation in crop breeding programs. The objectives of this study were (i) to analyze GE interactions on grain yield of one bread wheat (Triticum aestivum L.) and 19 durum wheat [T. turgidum L. subsp. durum (Desf.) Husn.] genotypes by the additive main effects and multiplicative interaction (AMMI) model, and (ii) to evaluate ...

Agricultural innovation and biotechnology development towards sustainable goals: can we make it more pro-poor?
Agriculture continues to change – driven by innovation and new technology. Genetics and breeding have revolutionised agricultural systems, and the 'Green Revolution', based on higher yielding varieties of dwarf wheat and rice, is arguably the greatest achievement in food crop development. Gene technologies now offer additional opportunities, where new traits improving crop protection ...

Intellectual property and Freedom To Operate in the flax breeding world: Canada in the global context
Through one-on-one in-depth interviews of Canadian public sector flax breeders, this study explores issues around Intellectual Property (IP) and Freedom To Operate (FTP) in flax breeding from a Canadian perspective. The results are supported by a scan of flax breeding efforts worldwide, an in-depth patent analysis (using Patent Lens and the US Patent and Trademark Office (USPTO) databases) and a ...

Variation in Adzuki Bean (vigna angularis) germplasm grown in China
Adzuki bean [Vigna angularis (Willd.) Ohwi & Ohashi] is cultivated in a wide range of agroecological environments from north to south China. An understanding of the genetic variation for crop adaptation facilitates plant breeding. A core germplasm of 231 accessions (selected from a representative collection of 3908 Chinese landraces) was evaluated at diverse locations in China in 1998 to (i) ...

Investing in people and evidence for sustainable farming
Evaluation of farming systems, new ideas and learning with practitioners should be part of a transformed agriculture. Food security is difficult to pin down. It can be explained simply as access to enough food. But behind that simplicity lies an interconnected web of factors — from food prices to agricultural practices, nutrition, natural resources, technology, trade and social ...

Getting seed to smallholders needs a business approach
A locally owned, alternative model of supplying affordable seed is working for Africa’s framers, says Joe DeVries. Smallholder farmers in Africa — mostly women — wage silent battles against the elements and other forces beyond their control to feed their families, their villages, their countries. They have historically taken the lead in feeding Africa and are destined to ...

Researchers Analyze Rapeseed Thioglycoside Transport Mechanism to Assist High-quality Breeding
Recently, Liu Shengyi, a researcher at the Institute of Oil Materials, Chinese Academy of Agricultural Sciences, and Yang Qingyong, a professor at the School of Information, Huazhong Agricultural University, collaborated to develop a new idea/method for the functional identification of multi-copy genes, and based on this identification, the important transporter BnaA06. GTR2 of glucosinolates in ...

The economic impact of climate change on European agriculture A new study has estimated how changes to climate might affect the value of European farmland. Based on data for over 41 000 farms, the results suggest that their economic value could drop by up to 32%, depending on the climate scenario considered- Farms in southern Europe are particularly sensitive to climate change and could ...

How `open source` seed producers from the U.S. to India are changing global food production
Around the world, plant breeders are resisting what they see as corporate control of the food supply by making seeds available for other breeders to use. Frank Morton has been breeding lettuce since the 1980s. His company offers 114 varieties, among them Outredgeous, which last year became the first plant that NASA astronauts grew and ate in space. For nearly 20 years, Morton’s work was ...

Rethinking food production for a world of eight billion
The World Food Programme and the Chinese government jointlyannounced that food aid shipments to China would stop at the end of theyear. For a country where a generation ago hundreds of millions of peoplewere chronically hungry, this was a landmark achievement. Not only hasChina ended its dependence on food aid, but almost overnight it has becomethe world’s third largest food aid donor. The key ...

The problems with the arguments against GM crops
New evidence shows that arguments against GM crops are unfounded, says Margaret Karembu. The year 2013 marked the 18th consecutive year of commercial cultivation of genetically modified organisms (GMOs) or now commonly referred to as biotech crops. And in just under two decades, the volume of land on which biotech crops are grown has increased from 1.7 million hectares in 1996 — the first ...

Crop gene banks are preserving the future of agriculture. But who’s preserving them?
As climate change makes crop diversity even more important, gene banks struggle to stay afloat. During the past few years of civil war in Syria, rebel fighters have destroyed Shia mosques and Christian graves, and burned and looted Christian churches while the Islamic State group has demolished priceless artifacts in the region. Nothing seemed sacred to the disparate groups vying for control of ...

Global warming to result in widespread crop loss to insects
Rice, corn and wheat loss rates could rise by up to 25% with every 1˚C increase to global temperatures as insects start to eat and breed more, new research has found. Led by researchers at Washington University, the study forecasts global warming of 2˚C to push the losses of these three crops up to approximately 213 million tons every year. This could have severe implications ...

A Conceptual model for describing processes of crop improvement in database structures
Rising research costs, broadening goals, intellectual property rights, and other concerns increase the need for robust management of crop improvement data. The data model of the International Crop Information System (ICIS) allows breeding processes to be recorded unambiguously in a relational database. This paper describes this model, which underlies the Genealogical Management System (GMS) of ...

The utility of molecular markers for Barley net blotch resistance across geographic regions
Molecular marker technology shows potential to select and combine favorable alleles via genotypic selection and can be used to develop improved crop cultivars with considerable resource savings. In the present investigation, the utility of molecular markers for net blotch resistance identified in Australian breeding material was investigated for Canadian breeding material. Screening 42 Canadian, ...

Small scale organic fertilizer production line is easy to operate and use
Organic fertilizer production line is the equipment for batch production of bio organic fertilizer, which plays a very important role in the development of agriculture. Organic fertilizer equipment makes organic fertilizer containing a large number of microbial strains from crop wastes and breeding wastes, such as straw, corncob, distiller's grains, chicken manure, pig manure and other livestock ...

Effects of linkage and Epistasis on intergeneration correlations in self-pollinated species
In breeding for self-pollinated crop cultivars, early generation testing and selection (EGT) is desirable because it allows for more resources to test superior lines and helps avoid the loss of desirable alleles that would occur if EGT is delayed. However, high intergeneration correlations (IGCs) are required for effective EGT. This study is conducted to determine the effects of linkage and ...

What is the development trend of organic fertilizer production process?
Organic fertilizer production process uses straw, livestock and poultry organic matter as raw materials, and harmless treatment of pollutants through equipment to produce organic fertilizer. This production project mainly uses chicken, duck, goose, pig excrement and crop straw as the main raw materials, uses the natural fermentation of microbial flora and organic matter, adds nitrogen release ...
