Genetics: Breeding and Genetics

In broilers, heat stress results in reduced feed intake, digestion inef­ ficiency, impaired metabolism, and death. Our objective was to initiate a study on the effects of heat stress by profiling the transcriptome of a metabolically active organ, the liver, from heat-stressed and non-heat­ stressed broilers. From 21 to 28 d of age, heat-stressed broilers were exposed to daily 7-h cycles of 35°C...

Quantitative Genetics, Genomics, and the Future of Plant Breeding

Quantitative genetics (in its various guises) has been the intellectual cornerstone of plant breeding for close to 100 years. While the roots of Mendelian genetics, and its rediscovery, are firmly in the hands of plant breeders, it was Fisher's (1918) variance decomposition paper that marks the modern foundation for both quantitative genetics and plant breeding. We are now embarking on the age ...

Plant breeding: Induced mutation technology for crop improvement

present forms of life are the product of three factors: • mutation, the fundamental source of heritable variation, • environmental factors, which influence the selection of those mutations that survive and reproduce, and • time, during which the genotype and environment constantly interact and evolutionary change is realized. Genetic variation found in nature does not represent the original spe...
