A single chromosome addition from Thinopyrum elongatum confers a polycarpic, perennial habit to annual wheat.

Journal of experimental botany - 1 Aug 2004

Abstract excerpt

Annual wheat displays monocarpic senescence, but amphiploids between wheat and its wild perennial relatives in the genus Thinopyrum generally display a polycarpic, perennial growth habit. In order to determine the chromosomal basis of this phenomenon, life-history characteristics were examined using Chinese Spring wheat and a complete Thinopyrum elongatum (2n=2x=14) chromosome addition series in a Chinese Spring...
