The bulk-population method of breeding differs from the pedigree method primarily in the handling of generations following hybridization. The F2 generation is sown at normal commercial planting rates in a large plot. At maturity the crop is harvested in mass, and the seeds are used to…
What is bulk breeding method?
Bulk breeding refers to a selection procedure in which the segregating population of self-pollinated species is grown in bulk plot (From F1 to F5) with or without selection, a part of the bulk seed is used to grow the next generation and individual plant selection is practised in F6 or later generations.
What is pedigree method of breeding?
Pedigree breeding is a method of genetic improvement of self-pollinated species in which superior genotypes are selected from segregating generations and proper records of the ancestry of selected plants are maintained in each generation.
What is mass pedigree method?
Mass Pedigree method. This method consists of selection among individual plants and their progeny during inbreeding following crosses between selected donor parents. The parents are normally crossed in a single cross system. The F2 populations are subjected to selection for apparent desirable traits viz.
What are the 2 methods of breeding?
Basically, there are two methods of breeding which are as follows:
- Inbreeding : Breeding of the related animals as sire (male) and dam (female) are known as inbreeding.
- Out breeding : Out breeding of unrelated animals as male and female is known as out breeding.
Is the aim of plant breeding?
Plant Breeding Objectives
To increase the crop yield. To raise plants with desired characteristics. To develop a disease-resistant crop. To develop plants that can tolerate extreme environmental stress.
Why pedigree method is important?
Excellent method for improvement of easily observable and high heritable characters. As pedigree record is maintained, information regarding inheritance pattern of characters can be obtained as and when required. Each plant can be traced back to its parent plant.
What is pedigree selection?
Pedigree selection is a breeding technique in which the breeder maintains the records of an ancestry of the cultivar which are called as Pedigree records. … It helps the breeder to improve specific individuals of the progeny line, revealing genes for desired traits.
Which is the quickest method of plant breeding?
The quickest method of plant breeding is the (d) mutation breeding. The primary methods for the improvement of crops along with a tissue culture and genetic engineering are the introduction, selection, hybridisation, and mutation breeding.

What is the process of breeding?
Breeding is sexual reproduction that produces offspring, usually animals or plants. … Breeding may refer to: Breeding in the wild, the natural process of reproduction in the animal kingdom. Animal husbandry, through selected specimens such as dogs, horses, and rabbits.
What is an advantage of inbreeding?
More than one ancestor can be duplicated in the same pedigree. It can concentrate the genes of a superior ancestor. It can fix a desired type relatively quickly. It may result in animals that are more likely to transmit their own traits regularly when they are used for breeding.
What is rice breeding and its methods?
An inbred rice variety is a pureline. This means that the offspring or succeeding generations produced by this variety will have the same genetic makeup. It is the result of a cross between two or more different varieties and subsequent selection through several cycles of self-pollination or inbreeding.
