Abstract

The use of tissue culture techniques for the international movement of potato clonal germplasm was studied. “Multi-meristem” cultures were established from virus-free plants by procedures described earlier by the authors. Well developed plantlets, regenerated aseptically from “nodal cuttings” of shoots produced in multi-meristem cultures, were used for international transfer. The medium contained the Murashige-Skoog mineral and vitamin components, with 2% sucrose, and was supplemented with 2 mg/l calcium pantothenate and 0.2 mg/l gibberellic acid. The cultures survived the mail shipment when 1% agar medium and small test tubes were used; polystyrene containers reduced damage due to abrupt temperature changes.

At the receiving end, higher survival rates during the recovery of plants was achieved through potting of plantlets regenerated from nodal cutting cultures.

A total of 43 pest and disease-free potato clones have been distributedin vitro from CIP to 10 different countries.

The training of technicians from developing countries played an important role in the application of these methods.

Resumen

Fueron estudiadas las técnicas de cultivo de tejidos para el movimiento internacional de germoplasma clonal de papa. Se establecieron “cultivos multi-meristemáticos” a partir de plantas libres de virus, siguiendo los procedimientos previamente descritos por los autores. Para la transferencia internacional se usaron plántulas bien desarrolladas regeneradas asépticamente a partir de “cultivos de nudos” de tallos producidos en cultivos multimeristemáticos. El medio contenía los minerales y vitaminas de Mura-shige-Skoog, con 2% sucrosa, y suplementado con 2 mg/l pantotenato de calcio y 0.2 mg/l ácido giberélico. Los cultivos soportaron mejor el viaje en correo aéreo cuando se usaron 1% agar y tubos de prueba pequeños; el uso de cajas de poliestireno redujeron el daño debido a cambios bruscos de temperatura.

En el lugar de destino, se obtuvieron tazas altas de sobrevivencia al transferir a macetas plántulas que habían sido regeneradas por cultivo de nudos.

Un total de 43 clones de papa libres de pestes y enfermedades han sido distribuídosin virto desde el CIP a 10 países diferentes. El entrenamiento de personal de las instituciones recipientes han jugado un rol importante en la aplicación de estos métodos.
