Mapping QTL having Sources and you can Shoot Morphological Faculties within the an excellent Durum Grain ? T. dicoccum Segregating Inhabitants within Seedling Stage

A segregating society from 136 recombinant inbred outlines based on a good mix within durum grain curriculum vitae. “Simeto” and the T. dicoccum accession “Molise Colli” was adult into the ground and analyzed for a number of capture and you may root morphological characteristics. A maximum of 17 decimal feature loci (QTL) was identified to have shoot dry weight, level of culms, and you may bush height as well as sources inactive pounds, volume, size, area, and amount of forks and you may info, to the chromosomes 1B, 2A, 3A, 4B, 5B, 6A, 6B, and you will 7B. LODs was in fact dos.1 so you can 21.six, which have percent out of told me phenotypic variability between 0.07 and 52. About three QTL have been mapped in order to chromosome 4B, certainly one of and therefore corresponds to new Rht-B1 locus and contains an enormous affect each other capture and options traits (LOD 21.6). Almost every other QTL that have particular effects on resources morphological characteristics were and known. More over, meta-QTL analysis try did evaluate brand new QTL identified regarding the “Simeto” ? “Molise Colli” segregating populace that have those explained from inside the previous degree from inside the grain, which have three book QTL outlined. Because of the complexity of phenotyping to own options attributes, further degree might be beneficial to confirm these types of countries due to the fact needs to have breeding software getting optimization off root function getting industry performance.
