Background and Environment Affect Phenotype02:27

Background and Environment Affect Phenotype

6.5K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal...

Frequency-dependent Selection01:21

Frequency-dependent Selection

22.0K
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.

Plant Breeding and Biotechnology

19.0K
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.

Types of Selection01:46

Types of Selection

40.5K
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...

Summary
This summary is machine-generated.

Selecting optimal cassava genotypes requires accounting for genotype-environment interaction (GEI). This study identified stable and high-yielding cassava varieties for improved fresh root yield and dry matter content.

Area of Science:

  • Agricultural Science
  • Plant Breeding
  • Genetics

Background:

  • Genotype-environment interaction (GEI) complicates selecting superior cassava genotypes due to biased genetic estimates.
  • Simultaneous improvement of multiple traits, considering yield and stability, is crucial for effective breeding programs.

Purpose of the Study:

  • To assess genetic variation and GEI effects on fresh root yield (FRY) and other key traits in cassava.
  • To identify stable and high-performing cassava genotypes for breeding programs.

Main Methods:

  • Utilized linear mixed models, including mean performance and stability (MPS) and multi-trait mean performance and stability index (MTMPS).
  • Evaluated 22 cassava genotypes across 47 environments (year x location) in Brazil using a randomized complete block design.
  • Analyzed genetic variance, GEI variance, heritability, and employed regression variance indices (e.g., RMSE) for selection.

Main Results:

  • High GEI variance () indicated significant genotype-environment effects on trait expression.
  • Broad-sense heritability averaged 0.37 for primary and 0.44 for secondary traits.
  • Genotypes BRS Novo Horizonte and BR11-34-69 showed promise for FRY, while BRS Novo Horizonte and BR12-107-002 were noted for dry matter content. MTMPS identified seven stable genotypes.

Conclusions:

  • GEI significantly influences cassava trait expression, necessitating stability considerations in genotype selection.
  • Methodologies integrating stability and productivity enhance the reliability of recommendations for new cassava cultivars.
  • BRS Novo Horizonte and other identified genotypes are valuable for future cassava breeding initiatives aiming for improved yield and stability.
