The awareness among the people regarding the food quality and food preference is due to the changes in their lifestyle. Due to these changes a huge demand for nutritionally rich quality food but there is no assured supply. Hence, there is tremendous pressure on the plant breeders to produce not only high yielding varieties but also to develop nutritionally rich varieties and hybrids among all the crop plants. Today’s breeders are targeting modern plant breeding techniques which will help them to develop varieties and hybrids as per their wish within the short period. Now a day the art of plant breeding is more of science and less of art. ‘Speed breeding’ technique is being targeted by most of the breeders from the developed countries in their research programme.
