Plant breeding is a numbers game and
also, time is a very important factor in the course of developing variety.
For instance, start from crossing to release
a variety takes about 8 to 10 years typically. However, with technology we have
today, molecular
markers, you will be able to see in a few minutes, that we can identify genes
using molecular markers and then
that process will speed up the breeding program in quite a few years.
So we can probably identify traits much quicker and more
accurately in a breeding population and it will speed our selection so we can
release a variety sooner, in 4 or 5 years. So today I want to touch a little bit
the technology we use in our breeding program. That is called molecular marker
assisted selection.
Basically we can go collect leaf samples from a plant and then we bring the
tissue back here to the grinding, then we run a P.C.R., which
generates a lot of DNA copies. And then we run a geosystem; will separate out
the bands from those banding patterns we are able to tell which genes are
present, which genes are absent in a particular plant. And then using that molecular marking information
we will go out and select our plants that carries the gene for a specific trait.
So that process will speed up the
accuracy and improve the accuracy of the selection and also speed up the process
of the selection. So and that is one thing we do up here in our breeding program
using molecular marker technology.
