This experiment was done to investigate in vitro propagation and nucleus seed production efficiency of Bangladesh Agricultural Research Institute (BARI) developed clone potato varieties. In vitro shoots of potato varieties BARI Alu-35, BARI Alu-36, BARI Alu-37, BARI Alu-40, BARI Alu-46 and BARI Alu-62 were used as planting materials and BARI Alu-7 was used as check variety. | Efficacy of in-vitro propagation among some advanced potato clones and evaluation of yield character for the production of nucleus seed
