What is mass selection?
Mass selection is the method of crop improvement used in plant breeding. It is commonly used for self-pollinated plants as well as for the cross-pollinated plants. A major population of plants are selected in this method. The plants are chosen on the basis of their phenotype and performance for the breeding.
What is selection in animal breeding?
Selection describes the process of choosing animals that meet the requirements of the breeding objective and will, in a breeding enterprise, pass particular traits onto their progeny. Selection should consider both subjectively measured traits (visual assessment) and objectively measured traits (genetic assessment).
What is the process of mass selection?
In mass selection, seeds are collected from (usually a few dozen to a few hundred) desirable appearing individuals in a population, and the next generation is sown from the stock of mixed seed. This procedure, sometimes referred to as phenotypic selection, is based on how each individual looks.
What are the three selection methods in animal breeding?
Methods of selection
Types of selection are individual or mass selection, within and between family selection, sibling selection, and progeny testing, with many variations. Within family selection uses the best individual from each family for breeding. Between family selection uses the whole family for selection.
What is mass in plant breeding?
Mass Selection: When a large number of plants of similar phenotype are selected and their seeds are mixed together to constitute a new variety is called mass selection. The population obtained from the selected plants would be more uniform than the original population.
Why is mass selection important?
Mass selection is one of the most important methods used in the breeding of plants. This is the type of breeding method used for self-pollinated plants. In this method, a large population of plants is selected. ... Plants from this group are selected and used for self-pollination or cross-pollination.
What are 4 examples of selective breeding?
Culling is a form of selective breeding. Rather than breeding two animals that display favorable traits, animals with undesirable traits (such as aggressive behavior) are removed from a population. Culling can be performed either by killing the individual or by spaying/neutering in order to prevent reproduction.
What is selection and breeding?
Selection of Breeding Stock. Selection is used as a tool for livestock improvement. A breeding stock is a group of males and females which act as parents of future generations. Selection is the process of allowing certain animals to be parents of future generations while culling others.
What is selective dog breeding?
Selective dog breeding is the procedure of breeding purposefully selected dogs with the intention to produce, preserve, or remove specific physical characteristics, mental traits, health conditions, skills, and aptitude.
In which crop is the method of mass selection?
The mass selection is practiced in the cross-pollinated crops and the self-pollinated crops which are selected for the phenotype appearance, which is done for the observable characteristic of the plant such as the height of the plant, grain size, etc. Hence, the correct option is 'C'.
What is individual or mass selection?
Individual or mass selection is the simplest, oldest and most often effective method of selection, where the best individuals are selected from a population on the basis of their own 'phenotypic value' compared to the population means, e.g., the largest individuals, the survivors of a disease, or according to their ...
Who gave mass selection?
GARDNER (1961) developed a method for mass selection in which a high level of environmental control is maintained to maxi- mize the heritability. With ten cycles of selection in the variety Hays Golden, he realized an average yield improvement per cycle of 2.68 percent (LONNQUIST, 1967).
What is selection explain?
Selection is the process of picking or choosing the right candidate, who is most suitable for a vacant job position in an organization. ... Selection of an employee is a process of choosing the applicants, who have the qualifications to fill the vacant job in an organization.
What is the most important factor to consider in selecting breed?
Four of the most important factors to consider when choosing a dog breed include temperament, size, cost and the needs and preferences of individual family members.
