Abstract

Genotypic differences in tiller development in autumn to early winter and their relations to overwintering ability in 6 varieties in Panicum maximum and Panicum coloratum were investigated. Tiller development and overwintering ability varied considerably with the varieties. The following four characteristics were considered to be important as the factors promoting the overwintering ability ; higher percentage of vegetative tillers by number in early winter, smaller number of aerial tillers per reproductive tiller, tiller development from lower nodes to upper ones in underground parts of mother tillers, and subterranean nodes located deep in the ground. Makarikari-grass fully met these conditions, followed by Tayutaka, Gatton and Green panic. Also varieties ranked Makarikari-grass>Tayutaka and Gatton>Green panic for overwintering ability. Natsukaze and Tamidori which did not meet the conditions were unable to overwinter successfully. These results show that tiller development, particularly tiller composition before wintering, affects the overwintering ability in Panicum.
