 precious rice is the need to overcome malnutrition and we know that the important component of nutrition is iron and zinc. So the objective of my study is to develop high yielding varieties with high iron and high zinc. So for this for to achieve this objective we develop breeding materials in IR and micronutrient rich japonica lines and we use the test tube approach to produce the plants from male organ or enter culture from these crosses. So what you see is the result of diheploid lines which is commonly known as DH lines also. So these DH lines these are the progenies from the test tube plants and as you can see there is a broad spectrum of variation as we are able to fix the recombinants different kinds of recombinants. So these DH lines is a very noble material because this is important to produce the indica rice with high iron and zinc from japonica donors and as well these material can be used to locate the regions on the chromosomes which govern high iron and high zinc and once these QTLs or genes are available that would accelerate the breeding breeding programs to transfer high iron and high zinc in the background of high yielding mega varieties. It will help the especially for the developing countries rice consuming countries because malnutrition is a major problem in those countries and if we are able to bring some high yielding lines with high iron and zinc so even a small change can affect can go a long way and it would be very useful for human health.
