Chipping Quality

A diallel series of crosses was made between parents with good processing quality and nonprocessing but well-adapted varieties and breeding clones to study the inheritance of chipping quality and tuber yield in potatoes. The progeny of the crosses were assessed in three widely differing growing environments and chipped from a range of storage environments. Principal component analysis for chip color indicated that the first (PCA1) and second (PCA2) principal components accounted for 84.4 and 5.0% of the total variability, respectively. PCA1 scores were highly correlated (P < 0.01) with the mean chip color scores of the 20 crosses measured over the 11 environments, whereas PCA2 scores were highly correlated (P < 0.01) with the standard deviations of the chip scores over storage environments. These results provide new information that supports the recently proposed concept of two genetically independent systems determining chip color, i.e., "overall chipping quality" and "chipping stability". Highly significant (P < 0.01) general combining-ability and nonsignificant specific combining-ability effects suggest additive genetic factors and high narrow-sense heritability for specific gravity. Combining-ability effects for yield traits were generally nonsignificant, which probably reflects the selection of parents with proven breeding value.Key words: Solanum tuberosum, stability, yield, specific gravity

Chipping Quality

Acceptable chip quality based on chip color was obtained in five potato cultivars freshly harvested in August, September and October. Placing the tubers in 5 °C storage severely impaired chip quality. Reconditioning the tubers at 21 °C for 2 weeks improved chip quality in the cultivar Kennebec harvested in October and in two experimental cultivars, F5208 and F5889 harvested in September and October. Tubers of the cultivars Warba and Irish Cobbler from all harvests failed to become reconditioned satisfactorily. Preconditioning tubers at 21 °C before storing them at 5 °C and then reconditioning at 21 °C improved chip color in all cultivars. The color improved to an acceptable level in tubers of Kennebec harvested in October and of the experimental cultivars harvested in September and October. In these also, preconditioning produced good chip color when tubers were chipped directly from 5 °C storage. Tubers from all harvests of the experimental cultivar F5889, including those harvested when immature in August, chipped well from storage at 5 °C after 5 weeks of preconditioning at 21 °C.
