The objective of this work was to determine soybean resistance inheritance to Heterodera glycines Ichinohe (soybean cyst nematode ? SCN) races 3 and 9, as well as to evaluate the efficiency of direct and indirect selection in a soybean population of 112 recombinant inbred lines (RIL) derived from the resistant cultivar Hartwig. The experiment was conducted in a completely randomized design, in Londrina, PR, Brazil. The estimated narrow-sense heritabilities for resistance to races 3 and 9 were 80.67 and 77.97%. The genetic correlation coefficient (rg = 0.17; p<0.01) shows that some genetic components of resistance to these two races are inherited together . The greatest genetic gain by indirect selection was obtained to race 9, selecting to race 3 due to simpler inheritance of resistance to race 9 and not because these two races share common resistance genes. The resistance of cultivar Hartwig to races 3 and 9 is determined by 4 and 2 genes, respectively . One of these genes confers resistance to both races, explaining a fraction of the significant genetic correlation found between resistance to these SCN races. The inheritance pattern described indicates that selection for resistance to SCN must be performed for each race individually. |

?Pera? orange is a scion variety widely grown in commercial orchards of various citrus-producing regions in Brazil due to the good acceptance of its fruits by the consumer market, both for fresh consumption and industrial processing. The development of clones or selections occurs by genetic mutations within genetic improvement studies with the different varieties, consisting of the selection of plants with superior quality and production characteristics to the variety of origin. In this perspective, this study aimed to evaluate the physicochemical characteristics of four ?Pera? orange selections (?D9?, ?D12?, ?D25?, and ?C21?) grafted on two rootstocks (Rangpur lime (Citrus limonia Osbeck) and ?Volkamer? lemon (Citrus volkameriana Tan. and Pasq.), under the semi-arid conditions of the São Francisco Valley, Brazil. The experimental design was completely randomized, in a 4 x 2 factorial arrangement, with the first factor corresponding to the orange selections (?Pera D9?, ?Pera D12?, ?Pera D25?, and ?Pera C21?) and the second factor corresponding to the Rangpur lime and ?Volkamer? lemon rootstocks, using five replications of 10 fruits. The physical characteristics evaluated were: fruit mass (g), diameter, and length (mm); fruit firmness (Lb), peel thickness (mm), number of seeds, and juice yield (%). The chemical parameters were determined through the contents of vitamin C, soluble solids (oBrix), and titratable acidity (g of citric acid 100 mL-1), also calculating the maturation index (SS/TA ratio). The interaction between rootstock varieties and orange scions (selections) induced differences in the physical and chemical attributes of fruits, with the Rangpur lime rootstock inducing better fruits for the orange selection ?Pera D-9?, which showed the highest values of fruit mass and diameter, associated with thicker peels, lower soluble solids content, lower acidity, and higher vitamin C content, while inducing higher values of fruit length and soluble solids content in the fruits of the orange selection ?Pera C-21?, and lower number of seeds and higher juice yield for the orange selection ?Pera D-12?. Based on these results, under these conditions, the physical and chemical characteristics observed in the fruits of the ?Pera? orange selections meet the standards required by the market of fresh fruits.
