Effect of height on the competitive ability of wheat with oats
Competitive ability of wheat is influenced by a range of attributes such as plant height, tiller number, and light interception. This study focused on the effect of plant height on weed competitiveness of a set of near-isogenic wheat lines (NILs). The set included seven bread wheat (Triticum aestivium L.) and six durum wheat (T. turgidum L.) cultivars, each having a semidwarf and tall ...

Introducing Dr. Beatrice Amyotte, Small Fruit Germplasm Development Program
The berry breeding program at the Agriculture and AgriFood Canada (AAFC) Kentville Research and Development Centre in Kentville, Nova Scotia, is now the Small Fruit Germplasm Development Program. The new approach to plant breeding will allow the fruit industry to be more involved in the release of new Canadian varieties of strawberries, raspberries, blackberries and grapes that are developed ...

Construction of an intraspecific linkage map and QTL analysis for earliness and plant height in Lentil
Earliness and plant height traits are key targets in lentil (Lens culinaris Medikus) breeding and are quantitatively controlled. Recombinant inbred lines (RILs) are useful in genetic mapping studies of quantitative traits. The objectives of this study are to develop a genetic map and identify genome regions associated with earliness and plant height using RILs derived from a cross between ‘Eston’ ...

Genetic basis of the low-Phytate trait in the soybean line CX1834
The low-phytate (LP) trait in plant seeds offers important nutritional and environmental benefits for food and feed uses. Mutants with reduced phytate content are commonly produced by chemical mutagenesis, as is the case for soybean [Glycine max (L.) Merr.] line CX1834. Quantitative trait loci (QTL) for LP in CX1834 have previously been reported, however the genetic basis for this trait has not ...

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 ...

A southern root-knot nematode resistance QTL linked to the T-Locus in soybean
Southern root-knot nematode [RKI; Meloidogyne incognita (Kofoid and White) Chitwood] is an important soybean [Glycine max (L.) Merr.] pest. When RKI resistance was introgressed from the highly resistant, gray pubescent breeding line G93-9009 into moderately resistant, tawny pubescent cultivars BoggsRR and BenningRR, higher than expected proportions of two advanced backcross populations had gray ...

Diversity and relatedness of common carpetgrass germplasm
Common carpetgrass (Axonopus fissifolius Raddi) is a stoloniferous, sod-forming species used sparingly as a turfgrass. No information is available regarding the relationships between germplasm accessions of this species. Accordingly, the initial objective of this study was to evaluate the relatedness of common carpetgrass germplasm for morphological and turfgrass performance traits. This was ...

Leaf area - How & why measuring leaf area is vital to plant research
It is easy to measure leaves, and they are also the parts of a plant most responsive to their environment. The combination of these two factors makes leaf area measurement extremely useful to scientists and growers. Besides, leaves are one of the main plant organs and are responsible for the productivity of a plant, and on a larger scale, of an ecosystem or a farm. Therefore, an understanding of ...

Genetic variability of a forage bermudagrass core collection
Bermudagrass (Cynodon sp.) is an important warm-season forage grass for the South and may have value as a bioenergy feedstock. The objective of this study was to measure the genetic relatedness among entries of the Cynodon clonal forage bermudagrass core collection and seven commercial forage cultivars using plant phenotype and molecular marker data from amplified fragment length polymorphisms. ...

Transgenic breeding: Perspectives and prospects
Transgenic technology serves to introduce gene sequences for expression of a desired trait. Production of transgenic plants is reported in many crops, but commercialization is limited to a few selected crops, such as cotton (Gossypium hirsutum L.), corn (Zea mays L.), soybean [Glycine max (L.) Merr.], and canola (Brassica napus L. and B. rapa L.). This paper presents the sequential processes of ...

Early growth of flint maize landraces under cool conditions
Cold stress is a major factor that limits the success of environmentally sound cultivation of maize in central and northern Europe. This study evaluated the early growth of seven groups of Swiss Flint maize landraces (Zea mays L. ssp. mays) of different geographic origin under controlled cool conditions by assessing shoot and root traits. Measurements of plants, subjected to a permanent cold ...

Stability of Cytoplasmic male sterility in maize under different environmental conditions
Cytoplasmic male sterility (CMS) is a maternally transmitted trait, whereby a plant is unable to produce viable pollen. Studies have revealed that this trait is a tool for enabling efficient and reliable coexistence between genetically modified (GM) and non-GM cultivation by biocontainment of GM maize (Zea mays L.) pollen. Maize has three types of male-sterile cytoplasm (T, S, and C), the ...

Can changes in canopy and/or root system architecture explain historical maize yield trends in the U.S. corn belt?
Continuous increase in the yield of maize (Zea mays L.) in the U.S. Corn Belt has involved an interaction with plant density. A number of contributing traits and mechanisms have been suggested. In this study we used a modeling approach to examine whether changes in canopy and/or root system architecture might explain the observed trends. A maize crop model was generalized so that changes in ...

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 ...

Ancient roots of wheat virus resistance
The DNA sequence of a gene responsible for resistance to a devastating virus in wheat has been discovered, providing important clues for managing more resistant crops and maintaining a healthy food supply. Wheat crops in the Americas, Asia, Europe, and Africa are regularly damaged by wheat yellow mosaic virus (WYMV), and there is a high demand for wheat varieties or cultivars that are resistant ...
