Morpho-anatomical adaptations to waterlogging by germplasm accessions in a tropical forage grass

Soil waterlogging reduces gas exchange between the soil and the atmosphere, leading to oxygen deprivation in the rhizosphere. Brachiaria spp. are the most widelysown forage grasses in tropical America. Among commercial Brachiaria grasses, B. humidicola shows superior tolerance to waterlogged soils based on maintenance of growth and reduced leaf chlorophyll loss and senescence. However, little i...

Waterlogging-induced changes in root architecture of germplasm accessions of the tropical forage grass Brachiaria humidicola

Waterlogging is one of the major factors limiting the productivity of pastures in the humid tropics. Brachiaria humidicola is a forage grass commonly used in zones prone to temporary waterlogging. Brachiaria humidicola accessions adapt to waterlogging by increasing aerenchyma in nodal roots above constitutive levels to improve oxygenation of root tissues. In some accessions, waterlogging reduce...

QTL Mapping of Agronomic Waterlogging Tolerance Using Recombinant Inbred Lines Derived from Tropical Maize (Zea mays L) Germplasm

Waterlogging is an important abiotic stress constraint that causes significant yield losses in maize grown throughout south and south-east Asia due to erratic rainfall patterns. The most economic option to offset the damage caused by waterlogging is to genetically incorporate tolerance in cultivars that are grown widely in the target agro-ecologies. We assessed the genetic variation in a popula...

Forage Value of Weed Species in a Grass Seeding

Weeds are a major problem in seeding rangeland and cropland to native grasses. However, many immature weedy forbs and grasses are palatable to cattle. Research was conducted using yearling cattle for weed control in big bluestem (Andropogon gerardii var. gerardii Vitman) seedings (1987, 1988) at Mead, Nebraska on a Sharpsburg silty clay loam (fine, montmorillonitic, mesic Typic Argiudoll) soil....

Germplasm Accessions Resistant to Straighthead in the USDA Rice Core Collection1

The USDA rice core collection, containing 1,801 accessions from 115 countries or sources and representing about 10% of the whole collection, was established by a stratified random-sampling method. A total of 990 accessions in the core collection that headed in 110 days or less and were 150 cm or less in height were evaluated for straighthead resistance on a 1 to 9 scale with 1 being very resist...
