Genomic prediction of crown rust resistance in Lolium perenne [PDF]

BMC Genetics, 2018
Genomic selection (GS) can accelerate genetic gains in breeding programmes by reducing the time it takes to complete a cycle of selection. Puccinia coronata f. sp lolli (crown rust) is one of the most widespread diseases of perennial ryegrass and can lead to reductions in yield, persistency and nutritional value.

Is stimulation of leaf photosynthesis by elevated carbon dioxide concentration maintained in the long term? A test with Lolium perenne grown for 10 years at two nitrogen fertilization levels under Free Air CO2 Enrichment (FACE) [PDF]

, 2003
Photosynthesis is commonly stimulated in grasslands with experimental increases in atmospheric CO2 concentration ([CO2]), a physiological response that could significantly alter the future carbon cycle if it persists in the long term.. Yet an acclimation

Differential Resistance Mechanisms to Glyphosate Result in Fitness Cost for Lolium perenne and L. multiflorum

Frontiers in Plant Science, 2017
Multiple mechanisms of resistance to glyphosate are exhibited by populations of Lolium spp. worldwide. Association of resistance with growth and reproductive fitness is an important predictor for long-term success of glyphosate-resistant (R) versus ...

Selection of meadow fescue for persistence under frequent defoliation

Grassland Research, EarlyView.
Meadow fescue was adapted to management intensive grazing in humid temperate regions. It does not tolerate highly intensive grazing with short rest periods or residual sward heights below 5 cm. This paper documents genetic progress in selecting for improved tolerance to frequent and close grazing.

Glucosinolate hydrolysis products for weed control [PDF]

, 2006
Glucosinolates are allelochemicals present in all Brassica plants. Upon hydrolysis by endogenous enzymes they produce a series of biologically active compounds, such as isothiocyanates and their deriva-tives among others.

Efficiency of Vegetative Filter Strips in Mitigating Soil Erosion and Surface Runoff

Land Degradation &Development, EarlyView.
ABSTRACT Vegetative filter strips (VFS) are widely used in agriculture to reduce soil erosion and sediment transport during heavy rainfall events. This study assessed their effectiveness in controlling surface runoff and sediment transport under controlled field conditions.

Water-Soluble Carbohydrate Recovery in Pastures of Perennial Ryegrass (Lolium perenne L.) and Pasture Brome (Bromus valdivianus Phil.) Under Two Defoliation Frequencies Determined by Thermal Time

Agriculture, 2020
The objectives of the experiment were to (i) examine the dynamics of WSC use and the recovery of leaf sheaths and blades of Bromus valdivianus Phil. and Lolium perenne L. subjected to two defoliation frequencies (DFs) determined by thermal time (TT); (ii)

Applying RGB- and Thermal-Based Vegetation Indices from UAVs for High-Throughput Field Phenotyping of Drought Tolerance in Forage Grasses

Remote Sensing, 2021
The persistence and productivity of forage grasses, important sources for feed production, are threatened by climate change-induced drought. Breeding programs are in search of new drought tolerant forage grass varieties, but those programs still rely on ...
