The inheritance of cold tolerance and turf traits in a seeded bermudagrass population
Low temperature tolerance is a principal factor limiting the use of seeded bermudagrass [Cynodon dactylon var. dactylon (L.) Pers.]. Therefore, increasing the winter tolerance of seeded bermudagrass cultivars has been a goal of turfgrass breeders for many years. Breeding methods for developing cultivars with increased tolerance to cold temperatures and superior turf characteristics could be ...

Occurrence of condensed Tannins in Wheat and feasibility for reducing pasture bloat
Bloat can be a serious problem for ruminant livestock grazing pastures of winter wheat (Triticum aestivum L.) in the southern Great Plains. Tannins in forage can reduce the incidence and severity of bloat. We measured the content and variability of total phenolics and condensed tannins (CT) in forage extracts from wheat varieties and experimental lines (ExpLines) to assess the feasibility of ...

New Method Provides Vital Information for Plant Breeding
Plants exhibit enormous variation in traits relevant to breeding, such as plant height, yield, and resistance to insect pests. One of the greatest challenges in modern plant research is determining which differences in genetic information cause such changes. Recently, researchers at the University of Düsseldorf in Germany and the Carnegie Institution of Science in the United States have ...

A comparative analysis of conventional and marker-assisted selection methods in breeding maize streak virus resistance in maize
Reliable information regarding comparative advantage of marker-assisted selection (MAS) over conventional selection (CS) in breeding for maize streak virus (MSV) resistance in maize (Zea mays L.) is scarcely available. A comparative study was, therefore, conducted to determine the efficiency of both methods in breeding for MSV resistance in Uganda. Backcross and selfed-progenies were derived from ...

How to create resilient agriculture
Durable food security and agricultural growth depend on development strategies with resilience built in from the start, says Gordon Conway. Economic growth with resilience to environmental threats will be central to the agenda of the UN Conference on Sustainable Development (Rio+20) in June this year, which aims to map out a pathway of sustainable development for the planet. The 'zero draft', ...

Bananas Face Another Extinction Crisis, Can Gene Editing Save Bananas?
Bananas are one of the most popular fruits in the world, however, in fact bananas are at stake and we may no longer eat them at any time. And the source of this crisis is fungal infection, and in 1950, an outbreak of a banana infectious disease with fungal infection called "Panama disease" directly led to the complete extinction of Gros Michel, the most widely planted banana variety at that ...

Conserving and enhancing maize genetic resources as global public goods–a perspective from CIMMYT
The growing demands for food, feed, and bioenergy worldwide will require a 2% per annum increase in global maize (Zea mays L.) production. Maize is one of the most important staple food crops across the developing world as well as being an important feed crop for global livestock production and the emerging biofuel industry. Maize genotypes can range from 0.5 to 5 m standing height at flowering, ...

New strategy of "two in one" rapid breeding
Xu Cao's research group from the Institute of Genetics and Developmental Biology, Chinese Academy of Sciences published a paper titled “A two-in-one breeding strategy boosts rapid utilization of wild species and elite cultivars” online in Plant Biotechnology. This study reports a new "two-in-one" rapid breeding strategy, which combines the new de novo domestication breeding method and ...

Choice of floating fish feed making machine system
1. Choice of drifting fish feed making maker system In order to maintain the attributes of pollution-free water products with delicious taste and also abundant nutrition, many individuals began to embrace the breeding method of developing their very own formulas, acquiring feed materials themselves, as well as handling as well as preparing them themselves. Therefore, ...

Diversity and mega-targets of selection from the characterization of a barley collection
Germplasm exchange is essential for assuring genetic gain in a breeding program. Two aspects of breeding programs are relevant to making them compatible for germplasm exchange: the amount of genetic diversity within programs and the identification of breeding programs with similar breeding objectives and environments of selection (i.e., mega-targets of selection). The objective of this study was ...

Evaluation of a simple method to screen soybean genotypes for salt tolerance
Excessive salt can reduce soybean yield [Glycine max (L.) Merr.] in grower fields. Salt-tolerant cultivars are needed to prevent field yield losses where excess salt is a problem. Soybean genotypes have primarily been evaluated for reaction to salt in the greenhouse using a labor-intensive and costly hydroponics method. A reliable, inexpensive method to screen soybean lines for salt tolerance ...

Classifying maize inbred lines into heterotic groups using a factorial mating design
A novel method of using a heterotic group's specific and general combining ability (HSGCA) to assign maize (Zea mays L.) inbred lines into heterotic groups has been proposed recently. The objectives of this study were to (i) assign maize inbred lines to known heterotic groups using this method and (ii) compare efficiency of this method to traditional and molecular methods relative to the ...

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 Saline Duper Wheat that Tolerates Higher Salt Concentrations!
In the past few decades, agricultural land has been largely lost, and increased salinity in soils around the world has received much attention. Nowadays, nearly 8% of the world's arable land can no longer be used for crop cultivation due to salt pollution, and more than half of the world's countries are affected. Wheat is the second largest grain grown after corn and grows more on Earth than any ...
