Resumo: | Our study focuses on the molecular analysis of the genetic diversity within 15 Tunisian durum wheat varieties and the assessment of the efficiency of some available markers to select valuable genotypes for technological proprieties of semolina (i.e. parameters related to SDS-sedimentation, mixing time and breakdown resistance of mixograph, grain protein content and yellow colour). While several markers were validated, others were not informative within the genotypes used. A high level of polymorphic information content (PIC) was detected, with an average of 5.2 polymorph alleles per locus and 0.6 average. Old varieties have high protein content however; modern varieties display strong gluten strength. Our results thus open the opportunity to choose valuable parents on the base of pedigrees, technological properties and genetic distances; and lead us to select efficient markers for the Regional Indigenous Land Strategy (Rils) selection strategy. |

Enquanto vários marcadores foram validados, outros não foram informativos dentro dos genótipos utilizados. Foi detectado um alto nível de conteúdo de informação polimórfica (pic), com uma média de 5,2 alelos polimórficos por locus e 0,6 média. Variedades antigas têm alto teor de proteína no entanto; variedades modernas exibem forte força de glúten. Nossos resultados abrem, assim, a oportunidade de escolher pais valiosos com base em pedigrees, propriedades tecnológicas e distâncias genéticas; e nos levam a selecionar marcadores eficientes para a estratégia de seleção da estratégia regional de terras indígenas (rils).EDUFU2019-08-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/4230110.14393/BJ-v35n4a2019-42301Bioscience Journal ; Vol. 35 No. 4 (2019): July/Aug.; 1002-1012Bioscience Journal ; v. 35 n. 4 (2019): July/Aug.; 1002-10121981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/42301/26645Tunisia; ContemporaryCopyright (c) 2019 Elyes Babay, Sameh Rahmani Mnasri, Rim Mzid, M'barek ben Naceur, Mohsen Hananahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBabay, Elyes Mnasri, Sameh Rahmani Mzid, Rim Naceur, M'barek ben Hanana, Mohsen 2022-01-26T12:09:02Zoai:ojs.www.seer.ufu.br:article/42301Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-01-26T12:09:02Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
