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
What is Point mutation? Definition of Point mutation A point mutation is a genetic mutation involving a change in a single nucleotide base in the DNA or RNA sequence, which can affect the sequence of amino acids in a protein. Causes of Point mutation Point mutations are primarily caused by various mechanisms that affect the … Read more
What is Missense Mutation? Definition of Missense Mutation A missense mutation is a type of point mutation in which a single nucleotide change results in the substitution of one amino acid for another in the protein sequence, potentially altering the protein’s function. Types of Missense Mutation There are two Types of Missense Mutation; Causes of … Read more
What is Nonsense Mutation? Definition of Nonsense Mutation A nonsense mutation is a genetic alteration that introduces a premature stop codon into the coding sequence of a gene, leading to the production of a truncated and often nonfunctional protein. Causes of nonsense mutation Nonsense mutations are a specific type of genetic mutation where a change … Read more
