Modern Miracles
When a technology comes along that unlocks a new way of thinking about an old problem, we marvel at it as a “modern miracle.” Growing up in Ireland, I know that memories of the Great Potato Famine still run deep. Today, Irish farmers know how fungicides have helped ensure that potato late blight remains a distant memory. Agriculture has come a long way since the nineteenth century, ...

Pre-Harvest Tips: How to Make your Harvest Data Deliver
Harvest is underway in some regions, but for much of the Midwest, late planting and the potential threat of early frost may make harvest a race against Mother Nature. No matter where you are, you’ll want to be ready the moment your crops are - and that means ensuring you’re set up to collect the data that is key to analyzing crop performance and making decisions for the coming season. ...

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 ...

The complex nature of GMOs calls for a new conversation
An honest discussion of genetically modified organisms must move beyond narrow concepts of human health to the wider social and environmental impacts of engineered crops. The GMO debate is one from which I’ve kept a purposeful distance. For one thing, it’s an issue that has already garnered more than its fair share of attention. For another, when you consider that many domesticated ...

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 ...

Feasibility of seed production from nonflowering orchardgrass
Nonflowering or sparse flowering orchardgrass (Dactylis glomerata L.) would greatly simplify management of intensive rotational grazing systems. Our objective was to quantify seed production on nonflowering orchardgrass clones selected in cold-winter climates, but grown for seed in mild-winter climates. We evaluated 98 orchardgrass clones for seed production traits at four locations. Most plants ...

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 ...

Comparison of certified and farm-saved seed on yield and quality characteristics of Canola
Relatively high seed prices and low canola (Brassica napus L.) grain prices created a controversy over using farm-saved seed from hybrids. Agronomic implications of saving seed from a canola crop were investigated by planting certified seed and saved-seed of an open-pollinated and a hybrid canola cultivar at eight site-years in Saskatchewan and Alberta, Canada. In one series of experiments ...

Pollinator effects on genotypically distinct soybean cytoplasmic male sterile lines
Poor seed-set limits potential for soybean hybrid seed production. The objective of this study was to evaluate effects of different pollinators on the rate of seed set in three soybean cytoplasmic male sterile (CMS) lines, JLCMS9A, JLCMS82A, and JLCMS89A. The following five treatments were applied under net room isolation-conditions: (i) insecticide application and release of alfalfa leafcutter ...

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 ...

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 ...

Heterosis decreasing in hybrids: Yield test inbreds
Yield testing finished inbreds to replace preliminary single-cross corn (Zea mays L.) yield tests will increase rate of commercial hybrid yield gains. Studies have shown that heterosis decreased 25%/50 yr, 10%/60 yr, and 35%/100 yr. Natural selection and artificial selection by plant breeders for adaptedness have increased parental inbred and hybrid seed yields, whereas percentage heterosis ...

A target region amplified polymorphism marker for fertility restorer gene rf1 and chromosomal localization of rf1 and rf2 in cotton
Cytoplasmic male sterility (CMS), a maternally inherited trait characterized as an inability to produce functional pollen, is an important biological system for economically producing hybrid seed to enhance crop yield and studying cytoplasmic and nuclear gene interactions. In cultivated tetraploid cotton (Gossypium hirsutum L.), male fertility in two systems CMS-D2 and CMS-D8 is restored by two ...

Genetic diversity in a core collection established from the main bean genebank in Spain
Common bean (Phaseolus vulgaris L.) is a traditional crop in many Spanish regions. A major collection of Spanish common bean landraces is maintained at the National Genebank in the Center for Plant Genetic Resources (CRF), Alcala de Henares, Madrid, Spain. A core collection including 200 common bean accessions was established from the CRF collection. We sought to analyze the genetic diversity of ...

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 ...

Interspecies transfer of resistance to anthracnose in lentil (Lens culinaris Medic.)
Lentil, Lens culinaris subsp. culinaris Medic., is an important legume crop on the Canadian prairies. Anthracnose, a fungal disease caused by Colletotrichum truncatum (Schwein.) Andrus & W.D. Moore, is a major barrier to seed yield and quality in lentil. Pathogenicity testing has revealed two races, Ct1 and Ct0, of C. truncatum in western Canada. No cultivar or landrace of cultivated lentil ...

Predicting outcrossing in maize hybrid seed production
Controlling pollination of the female inbred is critical to achieve maximum kernel set and high levels of genetic purity in maize (Zea mays L.) hybrid seed production. Although kernel set associated with inbred flowering dynamics is fairly predictable, it has not been possible to predict the level of outcrossing resulting from adventitious pollen entering the seed field. Our objective was to ...
