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...

Plant Breeding and Biotechnology

22.0K
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.

Chi-square Analysis02:46

Chi-square Analysis

44.6K
The chi-square test is a statistical hypothesis test. It is used to check whether there is a significant difference between an expected value and an observed value. In the context of genetics, it enables us to either accept or reject a hypothesis, based on how much the observed values deviate from the expected values.
The chi-square test was developed by Pearson in 1990.
The first step of performing a Chi-square analysis is to establish a null hypothesis, which assumes that there is no real...

Light Acquisition02:16

Light Acquisition

9.7K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Summary
This summary is machine-generated.

Recurrent selection (RS) effectively improved common bean plant architecture (PA) by 4.5%. This visual selection method in early generations also showed potential for increasing grain yield (GY) in later generations.

Area of Science:

  • Plant breeding
  • Agronomy
  • Genetics

Background:

  • Common bean producers in Brazil prioritize upright plant architecture (PA) for improved cultivation.
  • Controlling PA involves numerous genes, making recurrent selection (RS) a suitable breeding strategy.
  • Visual selection for PA in generation S₀ is common due to its high heritability.

Purpose of the Study:

  • To evaluate the genetic progress of recurrent selection for plant architecture (PA) in common beans.
  • To determine if selection progress varies with the number of selected progenies or the generation evaluated.
  • To investigate the impact of RS for PA on progeny grain yield (GY).

Main Methods:

  • Utilized data from S₀:₃ and S₀:₄ progenies across the fifth, eighth, and twelfth cycles of recurrent selection.
  • Performed combined analysis of variance on adjusted means of the 47 best progenies per generation and cycle.
  • Estimated genetic progress (GP) using linear regression analysis correlating adjusted means with the number of selection cycles.

Main Results:

  • Recurrent selection proved efficient, achieving an estimated genetic progress of 4.5% for plant architecture.
  • Analysis indicated that selection for grain yield (GY) can be successfully conducted in later generations based on heritability estimates.
  • Selection for PA in the F₂ generation was associated with increased progeny productivity.

Conclusions:

  • Recurrent selection is an effective method for improving plant architecture in common beans.
  • Visual selection for PA in early generations can indirectly benefit grain yield.
  • Future breeding efforts can leverage these findings for simultaneous improvement of PA and GY.
