Backcrossing is theplant breeding method most widely used to incorporate one or a few genes into an elite or adapted variety. In this method, the parent used for backcrossing has a large number of desirable attributes but lacks a few characteristics.50 Marker-assisted backcrossing is the simplest form of MAS.

What is backcross method of plant breeding?
Backcross method is applicable in all three groups of crop plants, viz. self-pollinated, cross pollinated and asexually propagated. 2. Parental Material: Backcross method involves two types of parents, viz. recipient parent and donor parent. The parent which receives a desirable character is known as recipient parent.
What is backcrossing in biology?
Backcrossing involves making an initial cross between the donor and recurrent parents. The resultant F 1 progeny have 50% of their genetic material from each parent (Fig. 1). F 1 individuals are crossed to the recurrent parent to develop a backcross one (BC 1) population.
What is the donor parent in backcross breeding?
The parent from which one or a few genes are transferred to the recurrent parent in backcross breeding. (has a gene of interest) and a recurrent parent (an elite line that could be made better by adding the gene of interest). The donor parent is crossed to the
What is the recipient parent in backcross method?
Backcross method involves two types of parents, viz. recipient parent and donor parent. The parent which receives a desirable character is known as recipient parent. The recipient parent is repeatedly used in the backcross method; hence it is also called as recurrent parent.
