An Overview Quantitative Trait Locus (QTL) mapping is a statistical technique used to identify the chromosomal regions responsible for the variation of a quantitative trait. The identification of QTLs is essential in understanding the genetic basis of complex traits and for the development of improved breeding strategies. An attempt has ... Read More

Introduction In the field of plant breeding, it is often necessary to combine desirable traits from two or more different varieties of plants. One way to achieve this is through the use of backcross breeding and heterosis breeding. Backcross breeding involves crossing a hybrid plant with one of its ... Read More

Introduction One of the most challenging aspects of modern genetic research is the identification of the genes responsible for a particular trait or disease. Genetic mapping techniques have been developed to identify quantitative trait loci (QTLs), which are regions of the genome that contribute to a trait. QTL mapping ... Read More

Introduction Genetic maps and physical maps are two types of maps that help us understand the structure of the genome. The genome is the complete set of genetic instructions that an organism inherits from its parents. Genetic maps and physical maps provide different types of information about the genome, but ...

Introduction Gene mapping is a critical process in modern genetics that involves identifying the locations of genes on chromosomes. This process can be used to study both qualitative and quantitative traits, which are two types of traits that vary in their patterns of inheritance. Qualitative traits are traits that are ...

An Overview Hybridization and introgression are two different but often conflated concepts in biology. Hybridization refers to the mating of individuals from different species or populations to produce offspring with mixed genetic characteristics, while introgression refers to the transfer of genetic material from one species or population to another through ...

Introduction Plant breeding is the process of altering the genetic makeup of a plant species to create new, more desirable varieties. It involves selecting certain individuals from a population and breeding them to produce offspring with specific traits. One of the key techniques used in plant breeding is foreground and ...

Introduction In recent years, the development of gene-based markers has revolutionized the way scientists’ study genetic variation in organisms Gene-based markers are specific segments of DNA that are associated with particular genes and can be used to identify genetic variation in populations. These markers have numerous applications in a variety ... Read More

Introduction Genetic mapping is a crucial tool in the study of inheritance and evolution. It allows us to locate the genes that underlie traits of interest, such as disease susceptibility, crop yield, or even behavior. Two main types of genetic mapping are used in modern research − Association mapping. ... Read More

Introduction Allele mining has emerged as a powerful approach to identify novel genetic variations that can be used to improve crop traits. TILLING (Targeting Induced Local Lesions IN Genomes) and Eco-TILLING (Ecotype Targeting Induced Local Lesions IN Genomes) are two widely used methods for allele mining in plants. These techniques ...
