In Pakistan, hybrid rice research began in 1991-92. In evaluations made during 1992-95, IRRI hybrids outyielded local varieties KS 282 and IR6 by more than 50%. For practical exploitation of hybrid rice technology, local Basmati and non-Basmati germplasm is being converted into commercially usable cytoplasmic male sterile (CMS) lines. 17156A is the newly developed Basmati CMS line (male sterility source, IR58025A). Restorers are being identified for this line.
