Outcrossing in early-stage spring wheat breeder seed development
Outcrossing (OC) during the initial stages of spring wheat (Triticum aestivum L.) breeder seed development ('head-rowing') may lead to off-types appearing in later generations of pedigreed seed. The objective of this research project was to measure OC in a simulated short (1.3 m) breeder row nursery of spring wheat. Rows of four cultivars known to differ in OC potential were grown at up to 12 ...

Ancestral landraces of common bean from the South of Europe and their agronomical value for breeding programs
Selection among breeding lines has been widely used to identify important cultivars and favorable alleles for adaptation, and resistance to abiotic and biotic stress. The objective of this work was to study the variability among common bean breeding lines selected from ancestral landraces, to evaluate the reaction of these lines to anthracnose (ANT) rust, common bacterial blight (CBB), halo ...

Modeling anthesis to silking in maize using a plant biomass framework
The capacity to predict time to silking relative to anthesis in maize (Zea mays L.) has important implications for breeding and seed production. We developed a theoretical quantitative framework for simulating the anthesis to silking interval (ASI) based on plant growth and biomass partitioning to the ear. We tested this framework to simulate the progress of silking relative to anthesis in nine ...

Current and potential development of perennial grasses in rainfed mediterranean farming systems
Past and recent development of perennial grasses in the rainfed Euro-Mediterranean region is reviewed concerning climatic constraints and main types of farming systems. The few Mediterranean cultivars that are registered and available are used for livestock production and cover crops only in subtemperate areas. These cultivars are adapted where annual rainfall exceeds 500 mm and accumulated water ...

Automated Seed Phenotyping with the Vibe QM3 [WEBINAR]
Join Dr. Edwin Reidel, Co-Founder of CID Agtech, Inc. and Mr. Ron Hadar, Chairman of Vibe Imaging Analytics to learn how the Vibe QM3 can help you to quickly count, measure, and classify seeds and grains based on size and color characteristics. Compared to tedious manual sorting and subjective visual inspection, the work in your lab will instantly become more objective and repeatable with the ...

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 ...

Genome Biology: Revealing the Genetic Structure of Seed Coat Content in Brassica Napus
The rapeseed team at Huazhong Agricultural University, Wuhan, China, published a research paper entitled “Multi-omics analysis dissects the genetic architecture of seed coat content in Brassica napus” in Genome Biology. This study has made important progress in the analysis of the genetic basis of skin shell rate, new gene mining, and regulatory networks for seed carbon source ...

Ecogeographic factors affecting inflorescence emergence of cool-season forage grasses
The ability to predict when a cool-season forage grass cultivar will begin inflorescence emergence under different ecogeographical conditions would allow plant breeders, agronomists, and grass-seed marketers to better position that cultivar into a forage production system. Our objective was to determine the ecogeographical factors (longitude, latitude, elevation, day of year when average daily ...

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 ...
