A.  aCloning of rootstock selections and Prunus spp. cultivars by softwood cuttings.h[electronic resource]  c2020  aThe goal of this research was to evaluate adventitious rooting capacity and root quality on softwood cuttings of 30 peach rootstock selections potentially tolerant to the Peach Tree Short Life syndrome (PTSL) from 2009/2010 selection cycle. Two trials were conducted with 15 clonal peach (Prunus persica) rootstock selections each, and three reference cultivars: ?Capdeboscq?, ?Okinawa? (P. persica) and ?Sharpe? [Chickasaw (P. angustifolia Marsh.) x Prunus spp.]. We concluded that propagation of peach rootstock selections by softwood cuttings is technically feasible, with rooting percentages ranging from 54.17 to 90%. The rootstock selections tested differ for most of analyzed variables, which allow distinguishing superior genotypes, but there is no difference among selections as the percentage of living rooted cuttings. Some selections (DB-SEN-09-23, SS-CHI-09-39 and SS-CHI-09-40) showed root formation and root quality similar to ?Capdeboscq?, similar (IR-ESM-09-01 and JB-ESM-09-13) to ?Okinawa?, similar (VEH-GRA-09-57) to both or even better (GL-ERA-09-33) than both reference cultivars. However, the selection FB-ESM-09-44 presented the worst root quality, with zero percentage of suitable rooted cuttings for transplanting.  aEnraizamento  aFruticultura  aPêssego  aPorta Enxerto  aPropagação Vegetativa  aPrunus Persica  aCapdeboscq  aOkinawa  aPTSL  aSharpe  aSíndrome de vida curta1 aUENO, B.1 aRICKES, T.
