Quick Answer: Why is plant breeding important?

Plant Breeding is not only important as an academic and applied research field but also as a practical profession in the development of novel varieties in food, feed, biobased (industrial, e.g. for fibers) and ornamental crops by plant breeding companies.

Why is plant breeding so important?

Plant breeding is a way to modify and improve plant species to achieve the needs and wants of humankind. Breeding is necessary to develop resistance to diseases and pests, to drought and temperature extremes, and to improve quality factors that can positively impact the lives of people throughout the world.

What is the most important method of plant breeding?

CROSS POLLINATED CROPS The most important methods of breeding cross-pollinated species are (1) mass selection; (2) development of hybrid varieties; and (3) development of synthetic varieties.

What is the impact of plant breeding on crop yield?

Many other striking contributions of plant breeding helped alleviate starvation. Plant Breeding is responsible for about 50% of crop productivity increase over the last century, while the remainder of the yield increase comes from better crop management (e.g., fertilization, irrigation, weeding).

Why plant breeding is an art and science?

Plant breeding is the art and science of changing the traits of plants in order to produce desired characteristics. Plant breeding can be accomplished through many different techniques ranging from simply selecting plants with desirable characteristics for propagation, to more complex molecular techniques.

What is meant by plant breeding?

plant breeding, application of genetic principles to produce plants that are more useful to humans. This is accomplished by selecting plants found to be economically or aesthetically desirable, first by controlling the mating of selected individuals, and then by selecting certain individuals among the progeny.

What is plant breeding and its objectives?

Plant breeding is a science based on principles of genetics and cytogenetic. It aims at improving the genetic makeup of the crop plants. Its objectives are to improve yield, quality, disease-resistance, drought and frost-tolerance and important characteristics of the crops.

How does plant breeding work?

Classical plant breeding uses deliberate interbreeding (crossing) of closely or distantly related individuals to produce new crop varieties or lines with desirable properties. Plants are crossbred to introduce traits/genes from one variety or line into a new genetic background.

How can plant breeding help reduce food prices?

Plant breeding has increased primary agricultural product supply by a significant amount, thus stabilising markets and reducing price volatility, according to the study results. This contributes to not only stabilising the prices and markets, but increasing potential world food supply.

How knowledge of genetics is useful in plant breeding?

The knowledge of gene and genome sequences, the regulation of gene expression and the molecular and cellular mechanisms and pathways behind plant architecture, development and function, have provided new opportunities for breeders to rationally design improvement programmes providing for more homeostasis in the

What is the nature of plant breeding?

Plant breeding is the production of plants by selective mating or hybridization. It is the traditional mechanism for producing new varieties of plants for horticulture and agriculture.

Why is plant breeding a science?

Plant breeding is the science of the manipulation of plant species, through pollination, genetic engineering, and selection of progeny, for the purpose of creating new and improved plant genotypes and phenotypes with desirable characteristics such as disease or insect pest resistance, salt or draught tolerance, crop

What is the role of plant breeding in green revolution?

The research focused on crops bred during the ‘green revolution’ of the 1960s, a period when agricultural scientists boosted yields by breeding smaller, hardier versions of common crops. Farmers used these alongside improved irrigation methods, strong pesticides and efficient fertilizers.

Who invented plant breeding?

In the 1860s, about the same time as Darwin, Gregor Mendel discovered he could cross breed different strains of pea plants and predict the traits of the offspring. He proposed that there was a genetic basis for inherited traits and demonstrated that he could control them.
