Which One Is Example Of Mutational Plant Breeding?

  1. The practice of mutant breeding includes introducing mutations intentionally through the application of chemicals or radiations (such as gamma radiations), and then choosing plants that have the desirable characteristic as a source for breeding purposes.

  3. Questions on the KCET 2022 Biology Exam

Mutations in the mung bean have been shown to be responsible for inducing resistance to yellow mosaic virus and powdery mildew. The process of mutagenesis can result in the creation of plants that are referred to as mutagenic plants or seeds.

What is mutation breeding in plants?

Mutagenesis may be induced intentionally in plants by the application of mutagenic chemicals, which can then be utilized for the generation of new, improved variations of species that originate from the original variety. The term for this kind of activity is ″mutation breeding.″

What are the steps in the process of mutation breeding?

  1. The following are some of the crucial stages involved in the process of breeding mutations: (vi) Evaluation of mutant.
  2. Q.
  3. 54.

What are the most significant advances that have been made through mutant breeding?Ans.The following is a list of the primary accomplishments of mutant breeding: (vi) Improvement in adaptability.

Q.55.Can induced mutations be used beyond a certain point?I The majority of the mutations are harmful to the organism.

Are micro-mutations of economic value in plant breeding?

Plant breeding is an area that can benefit economically from micro-mutations. How would you define a mutation that is fatal? Ans. A mutation is said to be fatal when it has the ability to cause the death of all persons who possess it.

What is the difference between mutation and classical breeding?

The process of mutation causes random genetic differences, which ultimately results in mutant plants with characteristics that are both novel and beneficial. Traditional breeding, in its most basic form, entails the selective multiplication of plants that have desired features and the eradication of, or ″culling,″ of plants that have characteristics that are less desirable.

What is mutational breeding in plants?

  1. The technique of exposing seeds to chemicals, radiation, or enzymes in order to develop mutants with desired qualities that may then be mated with other cultivars is referred to as mutation breeding.
  2. Variation breeding is another term that is used interchangeably with mutation breeding.
  3. The process of mutagenesis can result in the creation of plants that are referred to as mutagenic plants or seeds.

Which of the following are application of mutation breeding?

The improvement of morphological and physiological characteristics, resistance to illness, and quantitative characteristics including yielding ability have all been accomplished via the application of mutation breeding.

What is mutation breeding and its types?

Gene mutations, chromosomal mutations, and genomic mutations are the three primary categories that fall under the umbrella term ″mutation.″ However, mutation breeding is the process of accomplishing crop breeding by the introduction of mutagens to the cells of plants.

Which one is a mutant variety Pusa swarnim?

The cultivar of Brassica known as Pusa swarnim (karan rai) is resistant to the disease known as white rust. This question has a single correct answer: white rust. Oomycetes called Albugo candida are responsible for white rust (close relative).

What are some examples of mutations that can occur in plants?

The effect of a mutation may be striping on a flower or fruit, variegation, a distinct hue among blooms or foliage, bicolored flowers, a double flower amid singles, or any number of other possible outcomes. It is typical for roses, dahlias, and chrysanthemums to have ″genetically separate tissues co-existing inside the same plant,″ which is the definition of a chimera.

What are some examples of beneficial mutations in plants?

These advantageous changes include things like the ability to tolerate lactose, enhanced color vision, and in certain cases, resistance to the virus that causes HIV. Mutations that are advantageous can provide a benefit on the organism that possesses them, and over the course of evolutionary time, these mutations can spread across a population.

Which of the following is an example of mutation?

Angelman syndrome, Canavan disease, color blindness, cri-du-chat syndrome, cystic fibrosis, Down syndrome, Duchenne muscular dystrophy, haemochromatosis, haemophilia, Klinefelter syndrome, phenylketonuria, Prader–Willi syndrome, Tay–Sachs disease, and Turner syndrome are some other examples of common mutations found in humans.

How mutational breeding is different from conventional breeding?

Another frequent type of breeding technology that is far more efficient than conventional breeding is mutation breeding. Breeders will employ a variety of techniques to cause damage to the DNA in seeds, which will ultimately result in the introduction of mutations into the plant population.

What are types of mutation?

Different kinds of mutations Base substitutions, deletions, and insertions are the three different kinds of DNA mutations that can occur.

What is mutation breeding Slideshare?

  1. There are two different ways that mutation can take place: (1) by making a change in the DNA of the nucleus (point mutations), and (2) by making a change in the DNA of the cytoplasm (cytoplasmic mutation).
  2. The cytoplasmic male sterility mutation is the greatest example of a beneficial cytoplasmic mutation.
  3.  Freisleben and Lein are credited as being the ones who initially came up with the term ″mutation breeding,″ also known as ″Mutationszüchtung″ (1944).

Who gave the term mutation breeding?

Ans. In the year 1901, de Vries was the one who first introduced the phrase ″mutation.″ Q. 5.

What is Pusa swarnim?

EXPLANATION: Pusa Swarnim is a kind of Brassica that has been cultivated. It does not easily develop white rust. The oomycete Albugo candida or one of its near relatives is responsible for the development of white rust. The presence of chlorosis on the leaf surfaces, swelling of the roots, and white growths that resemble blisters in the stems are all indications of white rust.

Which of the following is are correctly matched 1 Brassica Pusa Gaurav 2 Pusa sem2 fruit borer 3 Pusa a 4 Bhindi 4 flat bean Pusa Sawani?

Aphids don’t seem to bother the Pusa Gaurav strain of brassica too much. Falt bean varieties Pusa Sem 2 and Pusa Sem 3 have a high level of resistance to jassids, aphids, and fruit borer. The okra types Pusa Sawani and Pusa A-4 are resistant to both the shoot borer and the fruit borer. The correct response is ″D.″

What is Pusa Gaurav?

The type of mustard or brassica known as Pusa Gaurav is resistant to aphids and other insect pests, and it is resistant to insect pests in general. Therefore, the solution that is right is ″Brassica.″

What is transgenic breeding?

Transgenic breeding makes it possible to transfer genes across species that are not linked to one another and even between organisms that are not related to one another. It facilitates gene transfer even across plants and mammals. One such example is the transfer of a gene from fish to grown tomatoes that confers resistance to cold temperatures.

How mutational breeding is different from conventional breeding?

Another frequent type of breeding technology that is far more efficient than conventional breeding is mutation breeding. Breeders will employ a variety of techniques to cause damage to the DNA in seeds, which will ultimately result in the introduction of mutations into the plant population.

What is ClB method?

A method that was developed by Muller to efficiently screen fruit flies for mutations that are deadly when carried on the recessive X chromosome. A recessive lethal marker (l), a dominant marker (B), and an inversion are all contained on the ClB chromosome (crossover suppressor C).

What is meant by mutagen?

Anything that has the potential to create a mutation is referred to as a mutagen (a change in the DNA of a cell). Mutations in DNA that are brought on by mutagens have the potential to damage cells and bring on a variety of illnesses, including cancer. Radioactive substances, x-rays, UV light, and certain chemicals are all types of environmental factors that might cause mutations.
