Abstract/Contents:"The within-variety variances were estimated at Perugia (Central Italy) for heading time, flag leaf length and width, and legth of the tallest stem in 22 varieties of Lolium perenne. The 22 varieties, grouped on the basis of their country of origin, were characterized by different levels of variability; the variances estimated in varieties from Holland, Denmark, France, and Germany were always higher than those of the Italian varieties, the differences being significant in 11 out of 16 cases. The highest variability observed in nonadapted types suggests the opporunity of reconsidering the vailidity of the ruels for which certilfied seed can move freely from one country to another because, uniformity being a character required for all the varieties, in cross-pollinated grass species the term "variety" can be applied to a particular population only in the area of adaptation."
