Selection indices to identify drought-tolerant grain sorghum cultivars
Menezes, Cícero Beserra de; Ticona-Benavente, César Augusto; Tardin, Flávio Dessaune; Cardoso, Mílton José; Bastos, Edson AlvesTwenty-five cultivars of grain sorghum [Sorghum bicolor (L.) Moench] were examined under both drought stress and normal conditions in 4 experiments. In each condition, genotypes were evaluated in a factorial experiment using a randomized complete block design with 3 replications. Eight drought tolerance indices including stability tolerance index, mean productivity (MP), geometric MP, harmonic mean, stress susc...
Heterosis and combining ability in bell pepper lines with resistance to multipl...
Nogueira, Danilo Gustavo; Carvalho, Regis de Castro; Maluf, Wilson Roberto; Nogueira, Douglas Willian; Ticona-Benavente, César AugustoThe aim of this study was to develop bell pepper hybrids with resistance to multiple pathogens and make inferences in regard to components of heterosis in hybrids obtained from lines presumed to be resistant to Pepper yellow mosaic virus (PepYMV), Phytophthora capsici, or Meloidogyne incognita. The studies were carried out in a greenhouse. We used ten lines, thirty experimental hybrids, and seven controls (Kona...

Assessment of resistances to multiple pathogens in experimental sweet pepper hy...
Carvalho, Regis de Castro; Nogueira, Douglas Willian; Ticona-Benavente, César Augusto; Nogueira, Danilo Gustavo; Maluf, Wilson RobertoThe aim of this study was to assess resistance to some of the major sweet pepper pathogens [Phytophthora capsici, Pepper yellow mosaic virus (PepYMV) and Meloidogyne incognita] in a group of experimental hybrids and their respective parental lines, and to identify hybrids possibly resistant to all three pathogens. Ten parental breeding lines, thirty experimental hybrids and seven commercial controls (Konan-R, M...
Combining ability of sweet pepper lines by multivariate diallel analysis - DOI:...
Nascimento, Ildon Rodrigues; Maluf, Wilson Roberto; Golçalves, Luciano Donizete; Faria, Marcos Ventura; Resende, Juliano Tadeu Vilela deThe objective of this work was to obtain information on the combining ability of sweet pepper lines by multivariate diallel analysis. Thirteen sweet pepper lines previously selected based on the reaction of sweet pepper yellow mosaic, being eight lines with resistance reaction and five susceptible lines, were used in a 8x5 partial diallel evaluated with the parental lines. The 53 genotypes were evaluated in gre...
