Genetic linkage mapping of an annual × perennial ryegrass population

Theoretical and Applied Genetics, 2004
Annual (Lolium multiflorum Lam.) and perennial ( L. perenne L.) ryegrass are two common forage and turfgrass species grown throughout the world. Perennial ryegrass is most commonly used for turfgrass purposes, and contamination by annual ryegrass, through physical seed mixing or gene flow, can result in a significant reduction in turfgrass quality ...

Mixtures of Persian clover with Italian ryegrass or barley-Italian ryegrass for annual forage

Canadian Journal of Plant Science, 1997
In the interior of British Columbia, spring barley (Hordeum vulgare L.) and Italian ryegrass (Lolium multiflorum var. italicum Beck.) are intercropped with fertilizer N as a 1-yr break before reseeding irrigated alfalfa (Medicago sativa L.). Persian clover (Trifolium resupinatum L.) was seeded with barley and ryegrass or only ryegrass to determine its

Surface water storage on annual ryegrass

Journal of Geophysical Research, 1961
Surface water storage is the water held on plant surfaces after the application of artificial rain. It approximates the storage component in interception loss equations. Surface ratio was shown by Horton [1919] to be a factor in interception loss by evaporation during a storm.

Distinguishing Annual From Perennial Ryegrass¹

Agronomy Journal, 1972
AbstractSince the fluorescence test for distinguishing seeds of Italian ryegrass (Lolium multiflorum Lam.) from those of perennial ryegrass, (Lolium perenne L.) is not always reliable, there is a need for a new method of distinguishing these species. This study was undertaken to determine temperature and nutritional requirements for rapid development ...

Aluminum effects on micronutrient uptake by annual ryegrass

Communications in Soil Science and Plant Analysis, 1989
Abstract Four ryegrass (Lolium multiflorumLam.) cultivars were grown in 1/5 Steinberg nutrient solution supplemented with six Al levels (0, 37, 74, 148, 296, or 592 umol L‐1) at pH initially adjusted to 4.2. Average net Fe influx was stimulated at low nutrient solution Al levels.

Genetic Parameters for Phenotypic Traits in Annual Ryegrass

Crop Science, 2019
Characterizing phenotypes in germplasm collections and making data publicly available is crucial to ensure the utilization of the accessions in breeding programs. Variance component estimates are used to calculate genetic parameters needed to make strategic decisions for germplasm conservation and its utilization in plant breeding.

Impact of seeding rate on annual ryegrass performance

Grass and Forage Science, 2004
AbstractAnnual ryegrass (Lolium multiflorum Lam.) is a primary forage resource for livestock producers throughout the south‐eastern USA during the winter‐growing season. It is important for livestock producers to begin grazing annual ryegrass as early as possible and any management practices maximizing early season production could be beneficial.

Divergent Selection for Anthesis Date in Annual Ryegrass

Crop Science, 1992
Anthesis date is the major factor controlling distribution of forage yield and quality of annual ryegrass (Lolium multiflorum Lam.) in the spring. This study was initiated to evaluate variation and selection response for anthesis date and to measure correlated responses in annual ryegrass. Four annual ryegrass cultivars were evaluated for heading date,

Competitive Relationships of Annual Ryegrass (Lolium Multiflorum Lam.)

Ecology, 1969
Annual ryegrass (Lolium multiflorum) competition with Kentucky bluegrass, hardinggrass, Blandon brome, wild oats, tall fescue, rose clover, and with itself was studied in greenhouse and field experiments. Ryegrass in a mixture of species always had a detrimental effect on the growth of other species.
