You asked: What is the process of pedigree?

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.

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).

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.
