“…Plant regeneration and transformation in potato has been reported using a wide range of explants including leaves, stems, tubers, and microtubers (Mitten et al, 1990;Visser, 1991;Snyder and Belknap, 1993;Dale and Hampton, 1995;Chang et al, 2002); using a variety of germplasm, including diploids, tetraploids, and Solanum species (Visser et al, 1989;Kumar et al, 1995;Park et al, 1995;Beaujean et al, 1998;Trujillo et al, 2001); and using several different methods (De Block, 1988;Wenzler et al, 1989;Sidorov et al, 1999;Romano et al, 2001). The number of plants produced is usually low for most varieties and dependent on the genotype used (Wenzler et al, 1989;Yee et al, 2001).…”
