    MORPHOLOGICAL CHARACTERIZATION OF POTATO VARIETIES UNDER IN VITRO AND IN VIVO CONDITION
    (Department of Biotechnology, Sher-e-Bangla Agricultural University, 2015-12) AKTER, KHADIJA
    The experiment was conducted at the Biotechnology l.aboratorv and research farm of Sher-e-Bangla Agricultural University (SAU), Dhaka during the period from April 2015 to March 2016 to study the morphological characterizalior1 of potato varieties under in "i/ru and in nyu condition. The sprouts ol potato varieties were used as explants and 4 times sub-culture were done to study the morphological parameter of plantlet. The highest length of shoot (5.19 ciii) was in the variety Diamant and it was lowest in Asterix variety. The maximum diameter of shoot (1.16 mm) was recorded from Asterix, while the minimum diameter of shoot (0.82 mm) from Diamant. Due to the interac(ion effect of difiërent varieties and number of explants. the highest length of shoot (6.00 cm) was found in Diainant variety' when 8 explants used in each culture. while the lowest length (4.10 cm) in Cardinal variety used 3 explant per vial. In vitro regenerated plantlets were acclimatized under in vivo field condition. The variety Diamant showed the best performance in respect of all the parameters under this study. The weight of minituher and yield per plant were highest in Dianmnt (10.23 gm and 114.16 gni) variety whereas the lowest in Asterix (8.15 gui and 64.46 gm) variety. (uba y: I-::
