The aim of this study was to determine whether the weeds accompanying potato crops can be a source of Alternaria spp. causing Alternaria leaf blight and to determine the genetic similarities of Alternaria alternata isolates infecting selected weeds: Chenopodium album, Cirsium arvense and tested potato cultivar. Three-year field experiment was conducted on the potato cultivar ‘Vineta N’. The isolates were classified into different species on the basis of macro- and microscopic features. In each year of the study, A. alternata dominated among the isolated fungi colonizing the leaves of potato plants and the selected weeds. The genetic similarities of A. alternata isolates was determined by the RAPD-PCR method. Tested genetic forms of A. alternata were closely related; only small differences in the pattern of the separated amplification products was evidenced. The dominance of A. alternata on the weeds accompanying potato crops suggests that if weed infestation is extensive, the pathogen is very likely to spread and its population to increase.

Breeding Selections

Tetraploid potato hybrids representing three genomic compositions (TTTT, TTPP, and TTPC (T, Solanum tuberosum; P, Solanum phureja; C, Solanum chacoense)) were constructed by crossing S. tuberosum (2n = 4x = 48) cultivars or advanced breeding selections among themselves or with 2n pollen producing selections of either S. phureja (2n = 2x = 24) or F1 hybrids between S. phureja and S. chacoense (2n = 2x = 24). Seedling families were evaluated in the fall season and selections within each family were evaluated in spring trials at Ait-Melloul, Morocco. Genomic composition was the greatest source of variance for yield-attributing traits, with TTPC outperforming other hybrids in fall trials for vine vigor, tuber set, and tuber yield and TTPP outperforming other hybrids in spring trials for the same traits. The results imply that analytic breeding for potato by construction of complex interspecific hybrids may result in clones surpassing a previously proposed heterotic threshold if the target environment is conducive to expression of favorable traits from alien germ plasm.Key words: Solanum phureja, Solanum chacoense, Solanum tuberosum, 4x–2x hybrids, potato, analytic breeding.

High Concentrations

The postanaerobic behavior of sweet potato roots from a flood-tolerant cultivar, 'Centennial,' and a flood-susceptible cultivar, 'Caromex,' was studied. High concentrations of CO2 and low concentrations of O2 were present in the internal atmosphere of 'Caromex' roots even after the anaerobically pretreated roots were restored to air for a few days, whereas in 'Centennial,' the internal gas atmosphere was less affected by anoxia. Ethanol accumulation in 'Caromex' was consistently higher than in 'Centennial,' and the postanaerobic changes were different between cultivars. An inducation of electrolyte leakage was observed from both cultivars immediately after roots were exposed to a CO2-enriched environment for 48 h. The leakage became greater in 'Caromex' after a 3-day aerobic exposure. In 'Centennial,' leakage of electrolytes due to CO2 treatment diminished at the end of 3 days. Application of ethanol to the discs had no immediate effect on electrolyte leakage in either cultivar under a N2 environment. However, anaerobiosis alone resulted in higher electrolyte leakage. It remains to be determined that the postanaerobic patterns of 'Caromex' and 'Centennial' are characteristic of flood-susceptible and flood-tolerant sweet potato cultivars in general.

Large Scale Field

The period of susceptibility of potato tubers to powdery scab (Spongospora subterranea) was studied by inoculating potato plants with spores, or by watering plants in infested soil, at different stages of plant development in greenhouse conditions. Maximum susceptibility began about 1 week before the stage when 50% of stolons had swollen to at least 5-mm diameter (tuber set), and ended 3-4 weeks later. With holding irrigation water during this period reduced the severity of powdery scab by 65-75% in field experiments in 1981-82 and 1982-83, but had no apparent effect on disease severity in 3 out of 6 large-scale field trials during 1984-85.

High And Low Temperatures

In recent years, processors in Tasmania have introduced Russet Burbank as the most desirable potato cultivar for processing into French fries. Malformed tubers, collectively known as second growth, have been observed in some commercial Russet Burbank crops with the main defect being knobby tubers. Second growth of potato tubers has been shown to occur when the plant suffers a period of stress during the growth of the tubers such as drought, high and low temperatures, restricted soil aeration, interference with water and carbohydrate translocation and fertility imbalance (Sparks, 1958; Bodlaender, Lugt & Marinus, 1964; Iritani, 1981; Holder & Cary, 1984) or a combination of both drought and high temperature stress (Ohms, 1968). If stress from these factors is relieved, the renewed growth of the tuber is often confined to the eyes, producing knobby tubers (Moorby, 1978). Moderate water stress during early tuber bulking can lead to pear-shaped tubers (pointed at the basal end) whilst water stress during the latter part of the season can lead to tubers pointed at the apical end (Iritani, 1981). Knobby tubers are undesirable because knobs are easily broken off leading to yield loss and the exposure of tissue to infection. Severely pointed tubers cannot be processed efficiently into French fries.
