Nutritional epidemiology of cancer: accomplishments and prospects.
Nutritional epidemiology of cancer has gone through several stages. Initially, the long latency of cancer, the difficulties in undertaking long-term cohort investigations or ascertaining remote diet in case-control studies, and the absence of convenient intermediate biomarkers of disease, such as cholesterol in cardiovascular diseases, discouraged studies on diet and cancer. Subsequently, howev...
متن کاملHorticultural Plant Breeding: Past Accomplishments, Future Directions
Genetic improvement of agronomic crops through breeding, which typically are marketed as commodities, are grower directed. Breeding objectives principally involve increasing yield, often based on resistance to biotic and non-biotic stress. For example improvement in hybrid maize yields have relied on increasing yield stability under high populations. In horticultural crops, breeding objectives ...
متن کاملIncreased nutritional value in food crops
Modern agriculture and horticulture must combine two objectives that seem to be almost mutually exclusive: to satisfy the nutritional needs of an increasing human population and to minimize the negative impact on the environment. These two objectives are included in the Goal 2 of the 2030 Agenda for Sustainable Development of the United Nations: 'End hunger, achieve food security and improved n...
متن کاملDeveloping heterotic groups for hybrid breeding in crop plants with emphasizing on forage crops
Exploitation of heterosis in hybrid breeding and development of synthetic cultivars is an essential procedure in plant breeding programs. The main goal of hybrid breeding programs is to select desirable parental genotypes to maximize the expression of heterosis. However, since development of high yielding hybrids and synthetic cultivars are costly and time-consuming, the accurate prediction of ...
متن کاملCassava Breeding I: The Value of Breeding Value
Breeding cassava relies on several selection stages (single row trial-SRT; preliminary; advanced; and uniform yield trials-UYT). This study uses data from 14 years of evaluations. From more than 20,000 genotypes initially evaluated only 114 reached the last stage. The objective was to assess how the data at SRT could be used to predict the probabilities of genotypes reaching the UYT. Phenotypic...
