Can someone tell me about the use of mutant plants in agriculture?

Have a look through these websites on mutant plants: a href="http://www.google.co.uk/#hl=en&expIds=17259,18167,27847,28101&xhr=t&q=mutant+plants+in+agriculture%3F&cp=0&pf=p&sclient=psy&site=&source=hp&aq=f&aqi=&aql=&oq=mutant+plants+in+agriculture%3F&gs_rfai=&pbx=1&fp=de610b7113b09eab" rel="nofollow"http://www.google.co.uk/#hl=en&expIds=17…/a A mutant plant (also known as a Sport), provided it is in someway an improvement on existing plants, can be grown on and help develop better plants.
