| Abstract:
Tubers from seven sweet potato clones were stored in baskets or on earthen floors in a well-ventilated building. Nearly all had storage periods not exceeding 20 days. In general, for the same storage periods, the percentage mean weight losses for the tubers stored on the floors were higher than the mean weight losses for tubers stored in the baskets. The differences were, however, significant only after 12, 16 and 20 days. There was no significant interaction between clones and treatments. Clones 81/10 and 80/29 had the lowest amount of rotted tubers irrespective whether the tubers were stored in baskets or on floors. The highest percentage mean reduction in dry matter occurred in clone 81/87 which was 23.7% for basket and 26.6% for floor. There was no significant interaction between clones and treatments in respect of dry matter loss. After storage, there was no significant increase in boiling or frying time due to the storage method used. The tubers from clone 80/29, however, had an undesirable fried taste. In terms of resistance to microbial infection, clones 80/29 and Makabie had the best storage characteristics. | |
