"Basic seeds" or minitubers of potato cv Banahaw and ASN 69.1, were derived from microtubers or "pre-basic seeds" produced in vitro. The microtubers ranged in size from greater than or equal to 5 mm to greater than or equal to 10 mm. Multiplication rate from microtuber to first generation (G1) minituber was 1:4 for both varieties. G1 minitubers ranged in sized from lesser than or equal to 10 mm to 40 mm. Generation 2 (G2) minitubers were produced from G1 minitubers at the rate of 1:4 for Banahaw and 1:5 for ASN 69.1. G2 minitubers ranged in size from lesser than or equal to 10 mm to greater than or equal to 45 mm. All microtuber production was conducted at the CMPB laboratory, IPB while all minituber production was conducted at the Bureau of Plant Industry, Baguio City [Philippines]. This basic seed production is a vital component of the microtuber production technology for the commercial production of certified seed tubers of potato introduced in 1992 by Rasco, Patena and Barba
