Now a days, speed breeding is beIng used to advance segregating generations by taking 4-6 generations in a year generally to develop RILs and other mapping population. should a breeder use this technique for varietal development program or not ? Why
SPEED BREEDING in one or another form has always been there in the breeders' bags for advancing segregating populations (eg, shuttle breeding). In recent years, it has gained a new phase of momentum, and resulted in the release of varieties in crops like wheat (DS Faraday), barley (Scarlett) and rice (YNU31-2-4). Keeping in view of the resources required and the outcomes expected and observed, the debate will continue for sometime; however, its role in shortening the time required from creation to fixation will always be undeniable.
Speed breeding is appropriate to reduce generation interval and to achieve the required output in a short period of time. This will enable scientists to feed the future generation which was increasing in an alarming rate in the world.
Absolutely Sir, it's an ideal option for the plant breeders to develop climate smart cultivars in a short period of time for sustainability and to ensure food and nutritional securities. As food demand is increasing exponentially due to burgeoning population.
Speed breeding in combination with Marker Assisted Back Crossing will help in transfer of desirable traits in very less time. We should exploit speed breeding where ever possible.
SpeedBreeding: Helpful for breeder to fix a target trait within a short period of time and one way of maximizing breeding genetic gain (By reducing the denominator (Cycle)). I’m collaborating with ILRI/BecA FLAIR fellowship, and we achieved to develop fixed line having wheat rust and quality genes within 1.5 years using marker assisted backcrossing (KASP platform). So, SpeedBreeding will be one of our future breeding tools to feed the growing population.
Knowing why and which regions of the genome mutate more than others could help breeders who rely on genetic variation to develop better crops.NEED MORE RESEARCH TO USE EFFICIENTLY.
