Plant Breeding and Biotechnology

17.2K
Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Frequency-dependent Selection01:21

Frequency-dependent Selection

20.2K
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

What is Natural Selection?

107.3K
Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.

Types of Selection01:46

Types of Selection

37.5K
Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...

Natural Selection and Adaptation01:15

Natural Selection and Adaptation

1.8K
Natural selection, a fundamental concept in evolutionary biology, is the mechanism by which evolution is driven, favoring organisms that are best adapted to their environments. This process enhances their chances of survival and reproduction. Adaptation, a key outcome of this process, involves genetic modifications that optimize an organism's functionality under specific environmental challenges, such as extreme cold or thinner air at high altitudes.
Beyond physical adaptations,...

Summary
This summary is machine-generated.

Selecting crop cultivars for high-yield environments unintentionally favors high stability regressions. For adaptation to poor environments, especially in developing agriculture, low regressions are needed. Systematic selection in poor environments is crucial, not just testing after high-environment selection.

Area of Science:

  • Agricultural Science
  • Plant Breeding
  • Genetics

Background:

  • Cultivar yield stability is often measured by regression analysis across diverse environments.
  • Selection for high-yield environments typically results in cultivars with high regression coefficients, indicating poor adaptation to low-yield conditions.
  • This poses challenges for agriculture in developing regions requiring adaptation to marginal environments.

Purpose of the Study:

  • To investigate the exploitation of genotype-by-environment (GE) interactions for improving cultivar adaptation to poor environments.
  • To propose a theoretical framework for selecting cultivars with low regression coefficients for enhanced stability in low-yield conditions.
  • To highlight the need for systematic selection strategies in target environments.

Main Methods:

  • Utilized simulation modeling to explore the effects of selection strategies on cultivar performance across environments.
  • Developed a theoretical approach based on genotype-by-environment (GE) interactions.
  • Analyzed the relationship between selection environments and cultivar regression coefficients.

Main Results:

  • Simulations demonstrated that systematic selection in poor environments is necessary for developing cultivars adapted to such conditions.
  • High-yield selection environments inadvertently select for high regression coefficients, limiting adaptability to poor environments.
  • Exploiting GE interactions can significantly reduce correlated responses across environments, potentially to zero.

Conclusions:

  • Cultivar selection strategies must be tailored to the target environment, particularly for marginal conditions.
  • Systematic selection in poor environments is essential for achieving adaptation and stability in those settings.
  • Further experimental studies are needed to validate the theoretical predictions regarding GE interactions and cultivar stability.
