N2  - Seedling progenies of three male sterile clones (GT 1, Ch 2 and RRII 35), along with progenies of a fertile clone (Mil 3/2) as standard, of Hevea brasiliensis were evaluated in the nursery.  Seed from the male sterile clones recorded early and higher percentage of germination.  The progenies of the male sterile clones were more vigorous compared to the control.  Test tapping yield also indicated the superiority of the progenies of male sterile clones.  The male sterile clones recorded higher heritability along with higher genetic advance indicating additive gene action.  They also had higher general combining ability.  Among the male sterile cloens, GT 1 showed significant superiority over the others
