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 ...

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 ...

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 ...

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, ...

Validation of molecular markers associated with net blotch resistance and their utilization in barley breeding
With the advancement of molecular marker technology and computer software, mapping quantitative trait loci (QTL) for complex traits in agricultural crops is frequent; however, exploitation of these QTL in practical breeding programs is limited. Here we report the validation of molecular markers linked to net blotch resistance QTL and their utilization in a barley (Hordeum vulgare L.) breeding ...

Mining and harnessing natural variation: A little magic
The success of a breeding program depends on having adequate diversity in the germplasm. However, as advanced breeding stocks and materials are generated, one casualty is the diversity itself. As a result, breeding programs in many crop species have reached a point of diminishing returns and it is feared that unless new diversity is infused into the breeding germplasm, we face catastrophic ...

Genome-wide reduction of genetic diversity in wheat breeding
Public concerns about crop uniformity introduced by modern plant breeding and genetic vulnerability to biotic and abiotic stresses have been one of the major forces driving long-term efforts in plant germplasm conservation for future food security. However, such concerns have gained little empirical support, as recent molecular diversity analyses of improved crop gene pools did not reveal much ...
