Abstract
The outcrossing rate of (Tectona grandis (L.)) was estimated from allo zyme segregation in progenies from 15 teak trees collected near Ngao, Thailand. The average single-locus outcrossing rate was found be 0.89, with a standard error based on the variation between loci of 0.08. Th e multilocus outcrossing rate was estimated to be 0.95 with a standard error based on re-sampling between progenies within families (bootstr apping) of 0.07. The results suggest that teak is mainly a outcrossing species. This result is in agreement with experiences from controlled pollinations.
