Abstract:
Genet ic variations and their selected effect s in M3 and M4 of Upland cotton radiated by60Co-Crayw ere studied. There w ere signif icant genet ic variations among M3 and M4 progenies,w hile there w ere obvious differencesbetw een dif ferent genoty pes and characters. Genetic variations for lintcot ton yield were obviously w iderthan those for f iber quality. New cotton varieties are bred with select ing g enetic variations radiated.
