Characterization Of Landraces Of Lotus Corniculatus L. In Uruguay, Mónica Rebuffo, María José Cuitiño
Characterization Of Landraces Of Lotus Corniculatus L. In Uruguay, Mónica Rebuffo, María José Cuitiño
IGC Proceedings (1997-2023)
Lotus corniculatus, the main cultivated forage legume in Uruguay since the sixties, is well adapted to soils with low P availability and pH where alfalfa has restricted growth. Local landraces are potential sources of valuable genes that could benefit the farming community. Traditionally farmers harvested their own seed through many generations in the southwest (Garcia et al. 1991), where sown pastures were rotated with cereals. These local landraces were conserved in situ in the past, but ley-farming systems have been substituted for continuous soybean cropping in recent years. INIA collected 110 samples for ex situ conservation with proper …
Breeding Forage Legumes To Complement Warm Season Perennial Grass Pastures In The Us Southern Region, Gerald R. Smith, F. M. Rouquette Jr.
Breeding Forage Legumes To Complement Warm Season Perennial Grass Pastures In The Us Southern Region, Gerald R. Smith, F. M. Rouquette Jr.
IGC Proceedings (1997-2023)
Perennial warm-season grass pastures, primarily bermudagrass (Cynodon dactylon [L] Pers..)) and bahia grass (Paspalum notatum Flugge)),, cover approximately 12 million hectares in the US southern region (US Census of Agric. 2002). These grasses are used for grazing, hay production or both. Bermuda grass and bahia grass are dormant from late fall until early spring with some variation in total dormancy period depending on seasonal conditions and latitude. Cool-season forage legumes can be over-seeded in the fall before the perennial grasses become dormant, providing winter grazing and nitrogen for the pasture system. The legumes sown in these grasslands are …
A Multi-Sensor Phenotyping System: Applications On Wheat Height Estimation And Soybean Trait Early Prediction, Wenan Yuan
Department of Biological Systems Engineering: Dissertations and Theses
Phenotyping is an essential aspect for plant breeding research since it is the foundation of the plant selection process. Traditional plant phenotyping methods such as measuring and recording plant traits manually can be inefficient, laborious and prone to error. With the help of modern sensing technologies, high-throughput field phenotyping is becoming popular recently due to its ability of sensing various crop traits non-destructively with high efficiency. A multi-sensor phenotyping system equipped with red-green-blue (RGB) cameras, radiometers, ultrasonic sensors, spectrometers, a global positioning system (GPS) receiver, a pyranometer, a temperature and relative humidity probe and a light detection and ranging (LiDAR) …
