Gametophytic self-compatibility and its influence on the physical characteristics of plum fruit

Gametophytic self-incompatibility can be one of the obstacles to achieving high yields in plum orchards. Therefore, we sought verify field, occurrence gametophytic self-compatibility and its influence on physical characteristics fruits Japanese accessions. The work was installed at Research Pole IDR-Paraná Ponta Grossa-PR, 2021, selecting six accesses belonging BAG-Ameixa site. experimental design completely randomized (DIC) with a split plot (6 x 2), having accessions subplot two methods pollination, induced self-pollination free five replications. For variables related quality fruits, DIC delimited, as treatment four replicates fruits. Data were analyzed using Rstudio software, applying Tukey test 5% level. observed for percentage apparent effective fruiting. total mass, seed pulp, vertical horizontal diameter, volume, pulp yield seed/fruit mass ratio evaluated. Free pollination higher fruiting, genotypes PR-1013 PR-1095 materials that presented highest percentages these variables, well evaluated considered self-incompatible not reached final maturity, being best method development
