End products are designed to suit specific environments. The first step involves the collection of plants or seeds for all possible alleles for all genes in a given crop, which is known as germplasm. c) Single Seed Descent Method. 2 Methods of Plant Breeding 2.1 Conventional Methods Plant breeding is defined as identifying and selecting desirable traits in plants and combining these into one individual plant. Conventional plant breeding is the development or improvement of cultivars using conservative tools for manipulating plant genome within the natural genetic boundaries of the species. • Only breeding method in which the . d) Modified Bulk Method e) Mass - Pedigree Method. Ammar ELAKHDAR. The number of genes that control the trait of interest is important to breeders. The parent with the desired trait, called the donor parent, provides the desired trait and may not perform as well as an elite variety in other areas. Targeted manipulation of the genetic material of plants by cross-breeding selected parent plants with subsequent offspring started in the 19th century. Breeding steps using the example of tomato - simplified illust ration. Thus, plant breeding is purely science with very little art involved. The method is generally used for handling segregation generation may be grouped into three categories. Ammar ELAKHDAR.
