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.
What is the 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 mass pedigree method?

The parents are normally crossed in a single cross system. The F2 populations are subjected to selection for apparent desirable traits viz.
What is the process of pedigree?
In pedigree method individual plants are selected from F2 and their progenies are tested in subsequent generations. A record of the entire parent off spring relationship is maintained and known as pedigree record.
Which method is also known as mass method or population method of breeding?

What are the advantages of pedigree?
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.
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.
How do you maintain a pedigree?
In keeping a pedigree record, the following should be kept in mind.
- Only important characteristics should be recorded. If a large number of characters are noted, the record keeping would become a great burden.
