Crossing between selected parent plants is the first step in pedigree method. Seeds obtained by hybridization (F1 seeds) are planted with proper sowing distance. Seeds of about 20-30 plants are harvested in bulk and forwarded to grow F2 generation. Selection is the main process carried in this step.
What is pedigree method in plants?
The pedigree method describes a selection protocol utilized during the inbreeding of populations of self- and cross-pollinated species in the development of homozygous lines. … Seed from a selected plant was grown in its own row the following generation (‘plant-to-row”, “head-to-row”, “ear-to-row”).
How do you perform a pedigree method of breeding in self pollinated crops?
This can be accomplished by first crossing a plant of the superior variety to a plant of the donor variety, which carries the trait in question, and then mating the progeny back to a plant having the genotype of the superior parent. This process is called backcrossing.
What is pedigree method of hybridization?
A selection method, which is used in segregating population of self-pollinated species and keeps proper record of plants and progeny selected in each generation is known as pedigree breeding. This method is widely used for the development of varieties in self-pollinated crops.

What is pedigree dog breeding?
An AKC Pedigree is a printed or electronic document that displays the lineage of an AKC dog and important information about the ancestors in a dog’s family tree.
What is pedigree record?
a zootechnical document that contains information on the origin, breed, growth and development, productivity, and other qualities of pedigree animals. Pedigree records are maintained in order to standardize the data needed to appraise pedigree animals and determine their use.
What are the main steps in breeding a new genetic variety of a crop?
The main steps in breeding a new genetic variety of a crop are:
- Collection of variability: …
- Evaluation and selection of parents: …
- Cross hybridisation among the selected parents: …
- Selection and testing of superior recombinants: …
- Testing, release and commercialization of new cultivars:
Which step is involved in the improvement through hybridization?
The improvement through hybridization involves the following three steps: 1. Selection of parents, 2. Production of F1 progeny, and 3. Selection of superior cones.
What are the methods of breeding in cross pollinated crops?

General methods (1) Plant introduction (2) Mass and progeny selection (3) Backcross method (4) Heterosis breeding (5) Synthetic breeding (6) Composite breeding II. Special methods (1) Mutation breeding (2) Polyploidy breeding (3) Transgenic breeding (4) Molecular breeding.
What are the steps of hybridization?
The major steps involved in the process of hybridization are:
- Selection of parents.
- Pollination or crossing,
- Harvesting F1 seeds,
- Further handling of the plants or distribution. Was this answer helpful?
What are the steps of hybridisation?
The steps involved in hybridization are:
- Selection of parents.
- Evaluation of parents.
- Harvesting and Storage of F1 seeds.
What are the steps involved in hybridization explain?
Crossing: Transfer of pollen grains from selected male flower to the stigma of the female emasculated flower. 5. Harvesting seeds and raising plants: The pollination leads to fertilization and finally seed formation takes place. The seeds are grown into new generation which are called hybrid.
What is a breeding process?
The animal breeding process starts with setting a goal; the breeder identifies traits that deliver improvements, for example for animals that show to be less susceptible for a certain disease. … The next step is selection; animals or groups of animals with the desired genetic traits are selected.
Which breeding method is best?
Outcrossing is the best breeding method for animals that are below average in productivity in milk production, growth rate in beef cattle, etc.
What are traditional breeding methods?
Traditional breeding: Modification of plants and animals through selective breeding. Practices used in traditional plant breeding may include aspects of biotechnology such as tissue culture and mutational breeding. Transgene: A gene from one organism inserted into another organism by recombinant DNA techniques.
