Abstract

New technologies on multiple scales are re-engineering to increase the number of crop cycles to achieve multiple generations of crops per year. The integration of speed breeding to existing crop breeding methods will expedite the research studies through rapid generation of crops. The time period for the crop varieties development could be reduced significantly. Also, it accelerates the progress of plant research in the activities viz., crossing, development of mapping population and adult plant phenotyping. Furthermore, this technique accelerate the introgression breeding for the pyramiding of traits.

Keywords
