In-vitro response of four TPS Parents viz., Atzimba, LT-8, MF-I and TPS-67 for root length, plantlet height, number of roots per plantlet, number of nodes per plantlet and survival percentage were studied at the Tissue Culture Laboratory, Biological Sciences Department, Quaid-i-Azam University, Islamabad from November 2004 to July 2005. IBA specific effect of TPS parents on numbers of root/plantlet, root length, plantlet height and number of nodes per plantlets was observed. Similarly, effect of treatment (IBA concentration) on numbers of root/plantlet, root length, plantlet height, number of nudes per plantlet and survival percentage of plantlets was highly significant. Plantlets cultured in MS medium produced maximum number of roots per plantlet (7.1), the longest roots (2.52 cm), and the highest survival percentage of plantlets (92.66%). Moreover, the tallest plantlets were recoded in MS medium (T1) and were at par with those cultured at T3 (1.5 pmm IBA + MS medium). Diff
