Five potato cultivars including one indigenous potato cultivar (Shilbilaty, as check cv) were
subjected with sucrose (a conventional carbon source), glucose and maltose in MS media and
evaluate their efficiency to in vitro growth profile. It was found that sucrose, glucose and
maltose containing media were statistically indistinguishable in their action to different growth
parameters. Sucrose-media were well capable in performing optimum growth but in some cases
glucose and maltose also performed well specially an increasing the nodal number per plantlet
(a fundamental of multiplication rate). Highest number of nodal countings was noted in maltose
media (cv. Shepody) compare to that of sucrose nutrients (cv. Shilbilaty). The fresh mass of
plantlet of all cultivars were also maximum in maltose medium except to this was All Blue.
Leaf proliferation were noted highest in maltose media (cv. Diamant) followed by glucose (cv.
Shilbilaty). The sucrose media results shortened internode than that of maltose and glucose
counterpart only exception to this was in Atlanta. In this experiment sucrose gave inferior
values than maltose and glucose. Maltose media improved growth status particularly in
Shepody, Atlanta and Diamant .
