Characterization of potato (Solanum tuberosum L.) adquirido de Centro Internacional de la Papa.

In vitro Plantlets formation potentiality of potato was investigated to establish a disease free plantlet system in potato. The study was carried out in In-vitro Preservation Lab, Plant Genetic Resource Institute (PGRI), National agriculture Research Centre (NARC) Islamabad, from January to February 2014. The germplasm of exotic potato is routinely maintained in In Vitro laboratory on MS media. Aim of the study was to investigate the effects of hormone on In Vitro virus free plantlet of potato. MS medium supplemented with 3 mg/L of BAP showed (5.79 cm) shoots fine performance in respect of multiple shoot regeneration in 6.5 days and (8.5) in MS+1mg/L BAP. Shoot length (4.0 cm) was observed in MS + 3mg/L BAP. Simple MS medium formed lowest number of shoot (2.14) per plant. MS + 6% sucrose + 3 mg/BAP combination of treatment show (20) shoots with length (6.5cm) in (25.5) days for in vitro virus free plantlets.
