Beef progeny testing report : 1973-1974 [PDF]

The drastic reduction in cattle prices with constantly rising costs of production emphasizes the value of superior genetic material. Although the costs of progeny testing have risen with other production costs, the positive identification of superior ...

Live animal measurements, carcass composition and plasma hormone and metabolite concentrations in male progeny of sires differing in genetic merit for beef production [PDF]

, 2009
peer-reviewedIn genetic improvement programmes for beef cattle, the effect of selecting for a given trait or index on other economically important traits, or their predictors, must be quantified to ensure no deleterious consequential effects go unnoticed.

Polymorphism of bovine STAT5A gene and its association with milk production traits in crossbred cattle of Kerala, India

Indian Journal of Animal Sciences, 2022
Signal transducer and activator of transcription 5A (STAT5A) is a transcription factor that mediates signals from prolactin and growth hormone, the corresponding main regulators of lactation and growth of mammals.

Elimination of a closed population of the yellow fever mosquito, Aedes aegypti, through releases of self-limiting male mosquitoes.

PLoS Neglected Tropical Diseases, 2022
Establishment of novel mosquito control technologies such as the use of genetically engineered insects typically involves phased testing to generate robust data-sets that support its safe and effective use as a vector control tool.

Resistance to Snow Mold as a Target Trait for Rye Breeding

Plants, 2022
Winter rye is a versatile crop widely used for food and industry. Although rye is resistant to abiotic stressors and many phytopathogens, it is severely damaged by pink snow mold (SM)—a progressive disease caused by the psychrotolerant fungus ...

Recent prediction tools for estimation of first lactation 305 days milk yield using monthly test days for genetic evaluation in crossbred cattle

Indian Journal of Animal Sciences, 2022
First lactation 305 days milk yield (FL305DMY) of progenies is an important criteria for selection of sires. In field progeny testing programme, prediction of FL305DMY based on test day records will reduce the cost of recording.

Spatiotemporal patterns of genetic variation for growth and fertility in Scots pine [PDF]

, 2011
Genetic testing plays an important role in tree breeding. Understanding basic genetic parameters for growth and fertility is a prerequisite for developing a successful breeding strategy to balance between short- and long-term gains.
