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 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
In this article we will discuss about the different methods for Breeding Cross-pollinated species What are Cross-pollinated species? Cross-pollinated species are plants that require pollen from a different individual of the same species to achieve fertilization and produce seeds. This process contrasts with self-pollinated species, where a single plant can fertilize itself. Cross-pollination is essential … Read more
What are self pollinated Plants? Self-pollinated plants are those that can fertilize themselves without the need for pollen from another plant. This process occurs when pollen from the flower’s own anthers (the part of the flower that produces pollen) transfers to its own stigma (the part of the flower that receives pollen). Self-pollination ensures that … Read more
In this article we will learn about different Modes of Reproduction and Pollination in Crop Plants. Modes of Reproduction in Crop Plants Crop plants exhibit two primary modes of reproduction: asexual and sexual. Each mode has distinct mechanisms and implications for plant breeding and agriculture. A. Asexual Reproduction Asexual reproduction does not involve the fusion … Read more
What is Plant Introduction? Types of Plant Introduction Plant introduction, a crucial aspect of crop improvement and agricultural development, can be categorized into two main types: primary introduction and secondary introduction. Each type serves distinct purposes and involves different processes to enhance crop varieties. 1. Primary Introduction 2. Secondary Introduction History of Plant Introduction The … Read more
In this article we will learn about Plant Breeding Introduction and objectives. Breeding systems: modes of reproduction in crop plants. Important achievements and undesirable consequences of plant breeding. What is Plant Breeding? History of plant breeding The history of plant breeding is deeply intertwined with the earliest human agricultural practices. As humans began to cultivate … Read more
