What is used to improve the phenotype of plants?
Plant breeding techniques such as hybridization, selection, and genetic engineering are used to improve the phenotype of plants. These methods help enhance desirable traits such as yield, disease resistance, and quality, leading to the development of improved plant varieties.
How are plants made resistant to pests?
The different methods of plant breeding for disease resistance includes seed selection, pedigree selection,recurrent selection,use of natural or artificial induced mutants etc.
What is pure line selection?
Pure line selection involves choosing and breeding individuals within a population that display desirable traits to establish a genetically homogenous line that consistently exhibits those traits. This method is commonly used in plant and animal breeding to develop stable and uniform varieties with specific characteristics.
Who has done plant breeding work before mendel?
Before Gregor Mendel, several ancient civilizations practiced plant breeding, including the Egyptians, who cultivated various crops, and the Chinese, who developed rice and millet varieties. In ancient Greece, Theophrastus documented plant selection methods, while Roman agriculturalists like Columella and Pliny also contributed to the understanding of plant cultivation and selection. These early efforts laid the groundwork for Mendel's systematic study of heredity in pea plants.
What is Plants breeding positives negatives selection?
Either positive or negative traits could be selected for in nature, although selection for negative traits is extremely rare. A good example of positive selection at a rapid pace can be seen in antibiotic resistance in bacteria. Negative selection usually occurs in domesticated plants and animals. Let's say you have a very tasty strain of tomatoes. Instead of keeping some so you have seeds for next year you eat, sell or can all of them. This leaves you with no seeds, therefore you've selected out the positive traits of that particular plant. I think this is what you are referring to.
What is a way you can use artificial selection?
plant or animal breeding
What is conventional plant breeding?
it is the identification and selection of desireble plants of desired charecters
How do you use artificial selection in a sentence?
Artificial selection, also called selective breeding, is a form of human intervention in plant or animal evolution.

What has the author V S Pustovoit written?
V. S. Pustovoit has written: 'Selection, seed culture and some agrotechnical problems of sunflower' -- subject(s): Sunflowers, Selection (Plant breeding), Seeds, Varieties
What is mass selection in plant breeding?
Mass selection is a breeding method where desired traits are selected based on the overall phenotype of the plants rather than individual performance. It involves selecting and propagating plants with desirable traits from a population to improve the overall genetic makeup of future generations. Over time, this can lead to the enhancement of certain traits within a population.
What does plant breeding and hybridization mean?
plant breeding means the process of producing new varieties of plants through selection and cultivation. hybridization means the union of the male gametes from a particular species with the female gamete belonging to another species to produce a new zygote. by Gougin chongloi
Which process is common practice that has been used by farmers for hundreds of years to develop new plant and animal varieties?
Breeding, normally through a process of selection
What is pure line selection?
Pure line selection involves choosing and breeding individuals within a population that display desirable traits to establish a genetically homogenous line that consistently exhibits those traits. This method is commonly used in plant and animal breeding to develop stable and uniform varieties with specific characteristics.

Why is it important to know the mode of reproduction of crops in plant breeding?
Knowing the mode of reproduction of crops is important in plant breeding because it influences the breeding methods that can be used to develop new varieties. Crops that reproduce sexually require different breeding strategies compared to those that reproduce asexually. Understanding the mode of reproduction helps breeders choose appropriate techniques to achieve desired outcomes in crop improvement programs.
