Why is seed selection important in agriculture?

The selection of seeds is used to improve the quality of yields. There are several diseases that are transmitted via the seeds. If the selected seeds are from the infected fields then the seed-borne diseases will cause severe problems in the agricultural process. Thus, always obtain seeds from healthy plants.

How is artificial selection used in agriculture today?

Artificial selection has long been used in agriculture to produce animals and crops with desirable traits. The meats sold today are the result of the selective breeding of chickens, cattle, sheep, and pigs. Many fruits and vegetables have been improved or even created through artificial selection.

What is the process of selective breeding in plants?

The process of plant breeding is theoretically simple, but its power resides in the fact that it creates novelty. A breeder generally selects two individuals for crossing, each of which has specific traits or characteristics of interest. Click to see full answer. Herein, what is selective breeding in plants?

How to select the right crop?

For those that want to interact in crop farming or, at the smallest amount , ensure financial sustainability, crop selection must consider marketability and profitability. In general, this means that the crop to be selected must be high yielding.

What is selection in plants?

One major technique of plant breeding is selection, the process of selectively propagating plants with desirable characteristics and eliminating or “culling” those with less desirable characteristics.


What is selection method in plant breeding?

Selection Method for Crop Improvement: It can be defined as preservation of certain individual plants of desirable characters. In simplest form selection means choosing plants of one’s choice. It is the basis of all crop improvement. Even today it is most common method of crop improvement among the cultivators.


What is the selection of seeds?

Selection of Seeds The seeds that are used to cultivate new crops have to be selected very carefully and of high quality. The good quality seeds can either be bought from different sources or farmers can produce by their own. The selection of seeds is used to improve the quality of yields.


Why is selection of seeds important in agriculture?

EXPLANATION: Selecting seeds which is high in quality is also an important factor that determines the growth of a good plant as seeds that are too tiny, broken and affected by harmful microorganisms can make the plant get infected that grows from it. So, only very best seeds must be sown.


What is selection in crop variety improvement?

Selection is the simplest and oldest breeding method. It can be defined as preservation of certain individual plants of desirable characters. The process of screening and evaluating superior plant species or varieties from domesticated or introduced plant material for the improvement.


Why is selection important in plant breeding?

A first requirement of any breeding program is to produce genetic variation in the characters that are to be improved. Once genetic variation is produced, it is necessary to select the desired types, which have a better expression of particular characters or combination of characters.


What is selection and sowing of seed?

Overall, selecting good quality seeds are essential for growing strong and healthy crops. SOWING OF SEEDS. Sowing seeds are necessarily the essential part of crop production. After the preparation of soil, the previously selected seeds are scattered in the field. This process is called sowing.


What is meant by crop selection?

Proper Crop Selection is a Factor in Successful Crop Farming. It is a requisite that must be undertaken before actually starting a farming venture. Even without a predetermined location and site of a farm, the crop to be grown can be decided based mainly on its marketability and profitability.


What is seed selection in agri crop production?

The selection of seeds is used to improve the quality of yields. There are several diseases that are transmitted via the seeds. If the selected seeds are from the infected fields then the seed-borne diseases will cause severe problems in the agricultural process. Thus, always obtain seeds from healthy plants.


What are the factors of seed selection?

Purity – should be clean / free from impurities. Maturity – should be of correct maturity stage. Age/storage period: – seeds stored for long periods have low viability/germination percentage hence should not be selected. Size of the seed, should be of correct size.


What are the steps in selecting and storing good seeds?

After harvest, clean seed and select full and uniform seed. Dry seed to 12−14% moisture content. Store the seed in sealed airtight containers until ready for planting (seed is good for up to one year if stored properly). Seed in non-airtight containers absorbs moisture and loses viability over time.


What are the precautions we have to take while selecting the seeds?

The following precautions should be taken while sowing seeds: (i) Seeds should be grown at proper depth. (ii) They should be sown at a proper distance apart from each other. (iii) Seed used for sowing should be clean, healthy and free from any disease or infection.


What is mass selection?

A method of crop improvement in which individual desirable plants are selected on the basis of phenotype from a mixed population, their seeds are bulbed and used to grow next generation is called mass selection. It is of two types, viz. positive and negative.


What is selective breeding?

Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.


What is the most ancient and basic procedure in plant breeding?

Selection. Selection is the most ancient and basic procedure in plant breeding.


How do plant breeders use genotypes?

Plant breeders may make use of genotypes selected for the desired environment by natural selection by considering the environment from which the germplasm they use is sourced . The identification of plant genotypes suitable for current or future environments may be achieved by searching in gene banks for accessions that have been sourced from wild or domesticated populations that are from environments that match the target production environment. This approach has been demonstrated to be useful in finding new sources of disease resistance in wheat genetic resource collections (Bhullar, 2009 ). This focused identification of germplasm strategy (FIGS) is designed to allow appropriate germplasm to be efficiently found in large collections. This approach should greatly increase the utilization of germplasm in seed banks, much of which has not been exploited to date because it is so poorly characterized and usually of unknown value especially in relation to potential contribution to environmental adaptation traits. Much of the resistance to abiotic stress that has been exploited in the past by plant breeders has come from wild sources. New tools will allow the process of finding the required genes to be more deliberate and efficient.


Why is crop breeding important?

Importance of crop breeding for food security. Agriculture faces growing global demand for food from population growth and strong growth in per capita consumption due to economic development especially in Asia (Henry, 2010 ).


How does the farming system affect crop selection?

System of farming adopted affects the crop selection. It depends on whether a farmer is doing purely crop farming or farming integrated with livestock production. Selection of crop depends on the crop production practices such as: Monoculture, Multiple Cropping, Hedge row-strip cropping,


Why are there wide possibilities in crop selection?

Wide possibilities in crop selection could be generated because of stable supply of water. In addition, the accessibility of the farm to and from the market will influence the selection of crops.


How does multi cropping help?

Adopting this cropping system helps in reducing the food crises of a country. Multi cropping system reduces the overall cost of production. For more than one crop growing on the same field that have similar water, sunlight, fertilizer needs helps to reduce the overall cost.


Why is multiple cropping important?

Multiple cropping system helps farmers to double their crop productivity and income. It also helps to reduce the dependency on growing a single crop in a particular growing season.


What is a biotic factor?

The biotic factor refers to living organisms including ruminant animals, insect and other pests, disease pathogens and weeds, also as organisms having beneficial effects like civet cat population for the assembly of civet coffee and therefore the abundance of pollinators.


What is multiple cropping?

Multiple cropping is the practice of growing two or more crops in the same farm land. Instead of growing one crop in a field we grow two or more than two crops in the field in the same season. But this doesn’t mean that we can grow any two or more crops together.


How has multiple cropping changed the way of farming?

Multiple cropping or Multi cropping system in agriculture has changed the way of farming. With continuous growing population in the world the demand of food supply is increasing every year. In every part of the world, mainly in developing countries like India there is a huge potential of growth in agriculture sector.


What is artificial selection?

What is the principle of natural selection?

Sometimes summed up by the phrase “survival of the fittest,” natural selection is based on the following principles: In nature, organisms produce more offspring than are able to survive and reproduce. Offspring with traits that make them more likely to survive, mature, and reproduce in the environment they inhabit pass on their traits to …


How does natural selection affect the environment?

Organisms therefore gradually become better-suited for their environment. If the environment changes, natural selection will then push organisms to evolve in a different direction to adapt to their new circumstances.


Why is artificial selection important?

Artificial selection has long been used in agriculture to produce animals and crops with desirable traits. The meats sold today are the result of the selective breeding of chickens, cattle, sheep, and pigs. Many fruits and vegetables have been improved or even created through artificial selection. For example, broccoli, cauliflower, and cabbage were all derived from the wild mustard plant through selective breeding. Artificial selection appeals to humans since it is faster than natural selection and allows humans to mold organisms to their needs.


What fruits and vegetables have been improved or even created through artificial selection?

Many fruits and vegetables have been improved or even created through artificial selection. For example, broccoli, cauliflower, and cabbage were all derived from the wild mustard plant through selective breeding.


What is the definition of offspring?

Noun. person who studies the natural history or natural development of organisms and the environment. natural selection.
