Fig. 1 Phylogenetic analysis of 22 Basmati, U.S. long-grain, and non-U.S. long-grain cultivars (a) using all 29 SSLP markers, (b) using only eight of the SSLP markers, Waxy, M7, M16, M22, RM220, RM224, RM234, and RM55. Scale bars show genetic distance as calculated by the ({Delta}µ)2 method of Goldstein et al. (1995)
