PERFORMANCE STUDY OF DIFFERENT POTATO VARIETY ON MERISTEM CULTURE (Pages : 28 - 31)

An experiment was conducted to select the suitable variety through meristem tip culture for potato chips production. Six varieties were used in this study viz. Laddy Rosseta, Astarik, Joity, Kenny Back, Kufri Bahar and Atlanta, at the Biotechnology Laboratory, A.H.Z Biotech Limited, Vadra, Rajshahi, Bangladesh during the period from November 2011 to March 2012. The chemical GA3 @ 0.25 mg/1 + and NAA @0.02 mg/1 with Murashige and Skoog (MS) medium were used in this study. It was observed that the variety Joity showed the highest explants survived (54%) and produced shoots and the lowest (39%) was found Atlanta. Days required for shoot appearance was significantly influenced on variety. The minimum (18) days for shoot appearance was found from Joity variety and took maximum days required for the variety of Atlanta (28). In respect of shoot length, node number, shoot diameter and root length always performed better in variety Joity than other variety. It was observed that variety Joity gave the highest fresh weight of shoot (0.75) and root (0.436 g). The highest yield (45 t/ha) and dry matter (28%) were found in Joity. It is concluded that the combination of GA3 @ 0.25 mg/l + NAA @ 0.02 mg/l performed better for regeneration and multiplication of potato cv. Joity and also yield and dry matter.Download
