WebOver the last few decades, the use of molecular markers has played an increasing role in rice breeding and genetics. Of the different types of molecular markers, microsatellites have been utilized most extensively, because they can be readily amplified by PCR and the large amount of allelic variation at each locus. Microsatellites are also known as simple … WebBackcross Breeding. In the BC breeding process, the donor genome is randomly introgressed into the RP background and the proportion of the RP genome in BC progeny is recovered at a rate of 1 – (1/2)t+1 for each BC generation (where t is the number of backcrosses), though plants of a specific BC population vary widely in the amount of …
