In pedigree method individual plants are selected from F2 and their progenies are tested in subsequent generations. … So each progeny inevery generation can be traced back to the F2 plant from which it isoriginated. This method used for selection from segregating population of crosses in self pollinated crops.
What are the steps in pedigree method?
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 do you mean by pedigree method?
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.
What is pedigree method in agriculture?
Pedigree method. In this method, individual plants are selected from F2 and subsequent generations and their progenies are tested. During this process details about the plants selected in each generation is recorded in Pedigree Record.
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 is SSD method?
Abstract. Single-seed-descent (SSD) is a modification of conventional plant breeding used by breeders to rapidly fix genes in breeding lines. As its name implies, SSD is the advancement of one randomly selected seed per plant through the early segregating stages (Goulden 1939; Brim 1966).
What is pedigree selection in animal?
In selection. …and quality is known as pedigree selection. Progeny selection indicates choice of breeding stock on the basis of the performance or testing of their offspring or descendants. Family selection refers to mating of organisms from the same ancestral stock that are not directly related to each other.
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 are the procedures of hybridization?
In the hybridisation process, the pollination is done when pollen should be viable and stigma should be receptive. To conduct the pollination, collect the fresh pollen from dehisced anthers of the male parents, and then gently dust the pollen onto the stigma of the emasculated flowers.
