“…Atlantic, one of the major chipping varieties in the United States, has the desirable processing qualities of high yield potential, high specific gravity, wide adaptation, and disease resistance (Webb et al 1978;Sterrett and Henninger 1997). However, Atlantic is also highly susceptible to IHN (Henninger et al 1979).…”

Internal Heat Necrosis of Potato—A Review

et al. 2008

Non-pathogenic necroses of potato tubers have been described in the literature since the early 20th century using different names including internal rust spot, internal browning, physiological internal necrosis, internal brown fleck, chocolate spot, internal brown spot and internal heat necrosis. These reports very likely describe either the same, or a collection of similar disorders, falling under the general umbrella of "internal necrosis", with the expression of symptoms being significantly altered via genotype by environment interactions. A number of widely-grown cultivars (e.g. 'Russet Burbank', 'Atlantic' and 'Yukon Gold') are susceptible to internal necrosis, making it an economically significant problem. In Atlantic, this syndrome has been termed internal heat necrosis (IHN) in the eastern United States by several investigators because heat and drought are believed to be important triggers of this condition. Investigators in the midwestern and western United States term this same or similar disorder internal brown spot (IBS). IHN and IBS are an internal physiological disorder of potato characterized by brownish red necrotic patches of parenchymal tissue that typically, though not always, occur along and/or inside the vascular ring. Several reports indicate that IHN is most commonly associated with the vascular ring tissue near the apical end of the tuber, but IHN may form anywhere in the tuber. In many cases, it is very difficult to distinguish between IHN and IBS, and several overlapping environmental factors are associated with each of these disorders. High day and night temperatures early in the growing season, combined with low rainfall, have been shown to increase the frequency and severity of IHN and IBS in several cultivars. Considerable research has examined the role of calcium in ameliorating IHN and IBS expression. Much of this work suggests an important role for calcium in the development of IHN, but other biotic and abiotic factors undoubtedly affect IHN and IBS expression. The biochemistry and genetics behind internal necroses of potato have historically been the leastresearched facets of this problem. Research has shown that enzymes involved in protecting cells from oxidative damage may be involved, and heritability studies have demonstrated that broad-sense heritability for IHN resistance is high. This review seeks to outline previous work on physiological internal necroses of potato due to high temperatures, summarize our current knowledge of IHN, and point to new areas of investigation to develop IHN resistant potato varieties.Resumen Desde comienzos del siglo 20 se han descrito en la literatura unas necrosis no patogénicas del tubérculo de papa, usando diferentes nombres, como herrumbre interna, oscurecimiento interno, necrosis fisiológica interna, punto oscuro interno, mancha chocolate, mancha marrón interna y necrosis interna por calor.

“…Since high N rates have been shown to delay tuber initiation (Marschner, 1986), compensation for reduced plant density might be more likely with low N rates since tubers should initiate earlier and would have more time to develop. Since heat necrosis is a common problem in the early summer in North Carolina (Sterrett & Henninger, 1997), delaying tuber initiation with high N rates might limit yields. In previous spacing experiments, excess fertilizer N may have suppressed the ability of cv.…”

“…Average yields throughout the southeastern (18.3 Mg ha -l) and southern (16.2 Mg ha -l) United States are lower than those in other U.S. potato production regions (18.8-31.2 Mg ha -1), perhaps due to climate, soil types, diseases, and production practices (Sieczka & Thornton, 1993). The potential production problems are relatively poorly drained soils, early-season frost damage due to late-winter planting and heat necrosis due to early summer high temperatures (Sterrett & Henninger, 1997).…”

SummaryExcessive fertilizer application in North Carolina, USA results in high residual soil levels of P, K and total soluble salts in potato fields. Our objectives were to determine the salt sensitivity of three common cultivars (Atlantic, Snowden and Superior), and the effects of planting density and fertilization on stand establishment, soilborne disease, and yield. Greenhouse results suggest that potato growth and emergence, but not shoot initiation, are reduced by high salinity. On a Portsmouth fine sandy loam, high fertilizer rates did not reduce stands of cv. Atlantic in the field in 1996 or 1997. Excess N resulted in more Rhizoctonia stem canker in 1996, and lower yields at the lower planting density in 1997. Yield compensation for reduced plant density occurred in 1997 at the lower N rates (56 and 112 kg N ha -l) and at the high PK rate (49 kg P and 139 kg K ha-l).

QTL for pitted scab, hollow heart, and tuber calcium identified in a tetraploid population of potato derived from an Atlantic × Superior cross

Common scab, calcium deficiency, and internal tuber defects, such as hollow heart, have severe negative impact on the marketable yield and profitability of potato (Solanum tuberosum L.) farmers. The present study was conducted to detect quantitative trait loci (QTL) controlling these traits. A tetraploid linkage map was constructed using 808 single nucleotide polymorphisms (SNPs) from the SolCAP 8300 Infinium Potato Array using 151 genotypes of an F1 population generated from a cross between cultivars with divergent traits, Atlantic and Superior. Atlantic is susceptible to scab and has high incidence of hollow heart and low tuber calcium. Conversely, Superior has resistance to scab, low incidence of hollow heart, and high tuber calcium. This population was phenotypically evaluated between 2009 and 2012. Seven QTL regions explained pitted scab incidence and severity; two on chromosomes 3 and 11 of Atlantic, and five on chromosomes 1, 2, 5, 6, and 10 of Superior were identified. Also, six QTL regions that explained tuber calcium variation were detected; four QTL were located on chromosomes 1, 4, 5, 7, and 8 of Atlantic; and one QTL on chromosome 3 of Superior. In addition, five QTL were identified for the incidence of hollow heart; two QTL were located on chromosomes 3 and 5 of Atlantic, and three QTL were located on chromosomes 3, 6, and 12 of Superior. These QTL regions can be further studied to develop markers for marker‐assisted selection.
