“…However, we found different heritability estimations for other tuber traits. For reducing sugar content, the heritabilities varied from 0.32 (Salamoni et al 2000) to 0.51 in spring and 0.73 in autumn (Chalá et al 2001). For dry matter content, the heritabilities varied from 0.38 (Salamoni et al 2000) to 0.72 (Rodrigues and Pereira 2003).…”

“…Solanum malmeanum stands out because of its frost tolerance and ability to cold acclimate at field conditions (i.e., increase cold tolerance after gradually increasing exposure to low temperatures), but also the capacity to be tolerant to heat ( Vega and Bamberg, 1995 ; Genesys, 2022 ). Valuable quality traits for industrial purposes such as high dry matter, high protein and low reducing sugar content in tubers were also reported ( Rocha et al., 2000 ; Chalá et al., 2001 ; Jansen et al., 2001 ) ( Table 4 ).…”

“…Limited studies were performed to assess the genetic variability and the few available ones do not fully cover these aspects. Important agronomical traits were documented, although comprehensive studies on this species are lacking and most of the references available for response to abiotic and biotic stresses ( Flanders and Radcliffe, 1992 ; Micheletto et al., 1999 ; Micheletto et al., 2000 ; Castelli et al., 2003 ) and quality traits for production and industry ( Rocha et al., 2000 ; Chalá et al., 2001 ; Jansen, 2001 ) are from occasional works or have evaluated S. malmeanum as “ S. commersonii ”.…”

“…3.6.4 Quality traits for production and industry 3.6.4.1 Tuber dry matter, starch and protein contents Solanum malmeanum has been reported (Table 4) to contain a range from 28.6% to 34.62% of dry matter content (Rocha et al, 2000;Jansen et al, 2001), 15.4 to 23% starch content (Jansen et al, 2001), 4.5% of protein in tuber dry matter content and 32.1% of amylose content in starch, with a mean particle diameter of starch granules of 45.8 mm (CV%=9.2) (Jansen et al, 2001). In addition, reducing sugars on its tubers have been evaluated from two different growing seasons, with an average of 0.22% in spring, and 0.33% in autumn, far below the levels presented in the reference cultivar 'Baronesa' (S. tuberosum) (Chala et al, 2001). A strong association in diploid S. malmeanum clones was verified between glutamate oxaloacetate transaminase (GOT) at relative mobility band 1.00 of electrophoretic standards and high dry matter content (average of 34.62 of dry matter content on tubers).…”

Solanum malmeanum, a promising wild relative for potato breeding

et al. 2023

View full text Add to dashboard Cite

Crop wild relatives are gaining increasing attention. Their use in plant breeding is essential to broaden the genetic basis of crops as well as to meet industrial demands, for global food security and sustainable production. Solanum malmeanum (Solanum sect. Petota, Solanaceae) is a wild relative of potatoes (S. tuberosum) from Southern South America, occurring in Argentina, Brazil, Paraguay and Uruguay. This wild potato has been largely mistaken for or historically considered as conspecific with S. commersonii. Recently, it was reinstated at the species level. Retrieving information on its traits and applied uses is challenging, because the species name has not always been applied correctly and also because species circumscriptions and morphological criteria applied to recognize it have not been consistent. To overcome these difficulties, we performed a thorough literature reference survey, herbaria specimens’ identification revision and genebank database queries to review and update the information available on this potato wild relative, contributing to an increase in research on it to fully understand and explore its potential for potato breeding. Scarce studies have been carried out concerning its reproductive biology, resistance against pests and diseases as well as tolerance to abiotic stresses and evaluation of quality traits. The scattered information available makes it less represented in genebanks and genetic studies are missing. We compile, update and present available information for S. malmeanum on taxonomy, geographical distribution, ecology, reproductive biology, relationship with its closest relatives, biotic and abiotic stresses resistance and quality traits and discuss ways to overcome sexual barriers of hybridization and future perspectives for its use in potato breeding. As a final remark, we highlight that this species’ potential uses have been neglected and must be unlocked. Thus, further studies on morphological and genetic variability with molecular tools are fundamental for an efficient conservation and applied use of this promising genetic resource.

“…Os teores de açúcares redutores, para a cultivar Atlantic, obtidos por este autor foram de 0,033% a 0,050%, abaixo do observado para as três cultivares. Chalá et al (2001) verificaram que a concentração de açúcares redutores no outono (0,59%) foi o dobro da primavera (0,28%), para as mesmas cultivares, uma vez que em temperaturas mais baixas, a conversão do amido em glicose ocorre mais rapidamente.…”

RESUMOObjetivou-se avaliar o efeito de doses e épocas de aplicação de adubo mineral sobre a produtividade e qualidade de batata na região centro sul da Bahia. Foram utilizadas 3 doses de N e K (75% da dose recomendada; dose recomendada de acordo com a análise do solo e 125% da dose recomendada); e 5 épocas de aplicação (100% no plantio; 1/3 no plantio e 2/3 na tuberização; 50% no plantio e 50% na tuberização; 1/3 no plantio, 1/3 na tuberização e 1/3 25 dias após a tuberização; 1/4 no plantio, 1/4 na tuberização, 1/4 25 dias após a tuberização e 1/4 50 dias após a tuberização). O delineamento experimental utilizado foi o de blocos ao acaso, em esquema fatorial 5 x 3, com quatro repetições. As características avaliadas foram: massa média dos tubérculos; produtividade de tubérculos; produtividade de tubérculos graúdos, massa seca, firmeza, sólidos solúveis, acidez total titulável e açúcares redutores. O parcelamento de N e K em duas aplicações (50% no plantio e 50% na tuberização) favoreceu maior produtividade de tubérculos em relação à aplicação total do adubo. A época de aplicação e as doses de N e K não promoveram variações significativas no teor de massa seca, acidez total titulável, sólidos solúveis e teor de açúcares redutores dos tubérculos da cultivar Vivaldi.Termos para indexação: Solanum tuberosum L., adubação, pós-colheita. ABSTRACTWith the purpose of assessing the effect of doses and application times of mineral fertilizers on the production and quality of tubercle potato, this experiment was carried out in the south center of Bahia and at the Universidade Estadual do Sudoeste da Bahia-UESB. Five application times were used (100% upon planting; 1/3 upon planting and 2/3 upon tuberization; 50% upon planting and 50% upon tuberization; 1/3 upon planting, 1/3 upon tuberization and 1/3 25 days after tuberization; 1/4 upon planting, 1/4 upon tuberization, 1/4 25 days after tuberization and 1/4 50 days after tuberization) and 3 doses of N and K (75% of the recommended dose; recommended dose according to soil analysis; 125% of the recommended dose; recommended dose according to soil analysis). The experimental outline was the factorial one (5 x 3), with plots arranged in randomized blocks with four repetitions. Tubercle productivity was assessed, as well as tubercle average weight, great tubercles productivity, great tubercles average weight, firmness, soluble solids, total titulable acidity and reducing sugars. The split application of N and K fertilization (50% upon planting and 50% upon tuberization) favored higher tubercles productivity in relation to the total fertilizer application. The application time and the doses of N and K did not promote significant responses in the dry mass, total titulable acidity, soluble solids and content of reducing sugars in the tubercles potato Vivaldi.
