“…Kalkmann et al (2013) and Marchese et al (2010) also verified high heritability values in experiments involving sweet potato clone selection for root-knot nematode resistance. According to Neves et al (2010), heritability estimates are fundamental in plant breeding programs, since they express reliability with which phenotypes represent genotypes.…”

“…There was a significant effect (p<0.001) among treatments for RF and RI in both physiological races. Kalkmann et al (2013), Marchese et al (2010) and Massaroto et al (2010), have verified similar resuts of differences in resistance to Meloidogyne spp among evaluated samples.…”

“…However, according to results obtained by Chaves et al (2013), Charchar & Ritschel (2004), Kalkmann et al (2013) and Marchese et al (2010), all four races have the ability to parasitize sweet potato.…”

“…Despite showing high yield potential, Brazilian yield is still low, due to -among other problems -the little care in crop management, the planting of obsolete and degenerated genetic materials and the use of cultivars which in their majority are susceptible the root-knot nematode (Marchese et al, 2010;Kalkmann et al, 2013). Among the major sweet potato pests, root-knot nematodes, Meloidogyne spp., are one of the most destructive for the crop.…”

“…According to Ferreira et al (2010), the most feasible and promising control strategy is the use of resistant cultivars. In recent years, several sweet potato cultivars and clones were selected in Brazil for resistance to root-knot nematodes, especially for M. incognita races 1, 2, 3 and 4 and M. javanica (Chaves et al, 2013;Charchar & Ritschel, 2004;Kalkmann et al, 2013;Maluf et al, 1996;Marchese et al, 2010;Massaroto et al, 2010).…”

The objective of this study was to evaluate sweet potato clones for resistance to root-knot nematode, Meloidogyne incognita races 1 and 3. For each nematode physiological race, a greenhouse experiment was set up in a randomized block experimental design with three replications and six plants per plot. Fifty-eight sweet potato clones from the UFVJM germplasm bank were evaluated, plus five commercial cultivars (Brazlândia Rosada, Brazlândia Branca, Palmas, Princesa and Coquinho), plus the cv. Santa Clara tomato (susceptible to Meloidogyne spp.). Stems were planted in 72-cell expanded polystyrene trays, filled with commercial substrate and inoculated with the pathogen thirty days after planting. Forty-five days after inoculation, the eggs were extracted, counted, and later evaluated. Resistance level classification was performed based on reproduction factor (RF) and reproduction index (RI). Among the 63 analyzed clones, a percentage of 78% were classified as resistant to M. incognita race 1.79% to race 3 and 67% showed multiple resistance to both M. incognita races.

Studies on the determination of genetic divergence among genotypes are important tools in breeding programs, contributing to the identification of parents with considerable productive potential. However, little is known about the combinatorial capacity of sweet potato (Ipomoea batatas) accessions and its adaptation to the different regions of Brazil. The objective of this study was to evaluate the morpho-agronomic traits from 102 sweet potato accessions from the Germplasm Bank of Embrapa Hortaliças. The experiment was laid out as an augmented block design comprised of 102 treatments. Nineteen above ground traits were measured using descriptors for the respective parts. Estimated values of broad sense heritability were high for the traits mean branch length (95.75%), immature leaf color (85.06%), and predominant branch color (90.57%). Coefficients of environmental variation were below 30.00% for all variables, except for branch weight (51.62%). The 102 clones analyzed presented broad genetic variability for the different traits evaluated, especially for branch weight, and branch length, and mature leaf color.
