13 Plant Breeding Methods I. Breeding Methods for Self-pollinated Crops 1. Breeding methods.
Another method for describing your breeds is to use the Purdy pedigree notation system. Both notations are described in this There is a very good explanation of how to write a maize pedigree in a CIMMYT Field Book .pdf but I don't know about the legality or availability of that document online. Here is a CIMMYT maize
Here we present a student-friendly software tool, Retromelon, for simulating the backcross breeding method. .. At the beginning of the laboratory session, the students are asked to write a schematic of the two main types of backcross programs (with a dominant and a recessive gene) to clarify the possible doubts and
With all of the advances in molecular biology, it may seem surprising to find out that traditional plant breeding methods are still needed in the development of plant varieties. Today, the backcross procedure is most often used to move a transgene from a good tissue culture variety that was used in transformation to an elite
7 Jul 2005 In fact, it is one of the few reliable methods to validate the additive effect of a quantitative trait locus (QTL) or a candidate gene. Here, I will review the various ways in which the backcross breeding scheme can still be useful in the field of modern genetics and highlight W. G. In: Newbury H.J, editor.

3 Feb 2010 This process is repeated for as many back crosses as are needed to create a line that is the recurrent parent with the gene of interest from the donor parent. BACKCROSS BREEDING METHOD. With each succeeding backcross generation, a greater proportion of the recurrent parent genes are obtained
within education in the future, plant breeding may need new ways to communicate its methods and principles. . The software provides a text editing window system named a “Tutorial" to write simple linear guides. . between markers and a qualitative trait and performs marker assisted backcrossing of a recessive disease
A technique used in plant breeding to introduce a desirable gene into a cultivated variety. Unlike the *pedigree method of plant breeding, the aim of a backcrossing programme is not to create entirely new varieties but to modify existing varieties. The cultivated variety (the recurrent parent) is crossed with the donor parent,
