The outcrossing rate is a key component of the breeding system. While estimates of outcrossing rate exist for some plants, less information is available on variation in outcrossing rate within species and on its causes. Since many features of flowers affect the level of outcrossing, plant breeding systems are often inferred 'from observations on floral morphology, physiology, and phenology. Typ...
Willet M. Hays was a great benefactor to plant breeding and the founder of the American Genetic Association (AGA). We commemorate the AGA's centennial. We mined university archives, U.S. Department of Agriculture (USDA) yearbooks, plant breeding textbooks, scientific periodicals, and descendants for information. Willet Hays first recognized the individual plant as the unit of selection and star...
Functional markers (FMs) are supposed to assist in diagnosis, disease treatment and turning plant and animal breeding more efficient. However, efficient FM application is challenged through current insights in the multi-organism nature of life. This letter aims to raise awareness for re-thinking concepts for FM development in plant breeding and proposes a novel perspective.
Efficient plant breeding methods must be developed in order to increase yields and feed a growing world population, as well as to meet the demands of consumers with diverse preferences who require high-quality foods. We propose a strategy that integrates breeding simulations and phenotype prediction models using genomic information. The validity of this strategy was evaluated by the simultaneou...
This article presents a holistic framework for understanding the science of plant breeding, as an alternative to the common objectivist and constructivist approaches in studies of science. It applies this approach to understanding disagreements about how to deal with yield stability. Two contrasting definitions of yield stability are described, and concomitant differences in the understanding a...
Luther Burbank (1849–1926), the best-known horticulturist in the United States, was honored in 1940 by having a U.S. postage stamp in his honor—as a scientist! Burbank became a legend in his time as the plant inventor and horticultural wizard releasing a prodigious 800 new cultivars, a number of which are still being grown, the most famous being the ‘Burbank’ potato, the ‘Santa Rosa’ plum, and ...
Over the past 50 years, thousands of rice varieties have been introduced by plant breeders to agricultural communities all over the world. Despite the improvement of attributes such as grain yield and tolerance to biotic and abiotic stresses, a significant portion of farmers still prefer local varieties over the improved cultivars. The main reasons for this perference are the absence of a dire...
