What is Pureline Selection? Pureline selection is a plant breeding method used to develop new varieties from a single genotype or “pure line.” This approach is based on selecting and propagating individuals that consistently exhibit desirable traits, aiming to create a genetically uniform and stable line. Here’s how it typically works: Pureline selection is particularly … Read more
What is bulk Method? The bulk method is a plant breeding technique used to develop new varieties by selecting plants with desirable traits through repeated cycles of selection and propagation. Here’s a brief overview of how it works: The bulk method is often used in the early stages of breeding programs to quickly evaluate and … Read more
What is Backcross Method? The backcross method is a genetic technique used in plant breeding and animal genetics to transfer a specific trait from one organism to another while maintaining the genetic background of the recurrent parent. This method involves several key steps and objectives: Key Concepts of the Backcross Method Advantages of the Backcross … Read more
What is Backcross Method? Definition of Backcross Method The backcross method is a breeding technique where a hybrid or progeny is repeatedly crossed with one of its original parent plants to transfer specific traits from the donor parent to the recipient parent while preserving the recipient’s original characteristics. Requirements of a backcross programme To effectively … Read more
What is Bulk Method? Definition of Bulk Method The bulk method, developed by Nilsson-Ehle in 1908, is a plant breeding technique where large quantities of plants from the F1 generation and subsequent generations are grown in bulk. Individual plants are only selected and evaluated after a prolonged bulking period, distinguishing it from methods like the … Read more
What is Pedigree Method? Definition of Pedigree Method The pedigree method is a plant breeding technique where individual plants from segregating generations are selected and documented through detailed pedigree records. This method aims to develop genetically uniform pureline varieties by maintaining and selecting plants until progenies exhibit no further genetic variation. Procedure for the Pedigree … Read more
What is Pureline Selection? Definition of Pureline Selection Pureline selection is a plant breeding method where individual plants are selected from a self-pollinated crop, and their progeny are evaluated. The best-performing progeny, derived from a single homozygous plant, is released as a pureline variety, ensuring genetic uniformity. History of Pureline Selection Characteristics of Pureline Selection … Read more
What is Mass Selection Method? Definition of Mass Selection Method Mass selection is a plant breeding method where a large number of plants with desirable traits are selected based on observable characteristics, and their seeds are pooled together to create a new variety. This method aims to improve the population’s uniformity for these traits while … Read more
What is Inbreeding depression? Definition of Inbreeding depression Inbreeding depression is the reduced biological fitness and health of offspring resulting from the mating of closely related individuals, which increases homozygosity and exposes deleterious recessive alleles. History of Inbreeding depression History of Inbreeding Depression Effects of Inbreeding Inbreeding, or the mating of closely related individuals, has … Read more
