Genetic Resistance
Genetic control and combining ability of agronomic attributes and northern leaf blight-related attributes in popcorn
Authors: J.S. Santos, A.T. Amaral J�ºnior, M. Vivas, G.S. Mafra, G.F. Pena,F.H.L. Silva and A.G. Guimar�£es
The present study was conducted to investigate the genetic control and to estimate the general and specific combining abilities of popcorn for agronomic attributes and attributes related to resistance to northern leaf blight (NLB). The 56 hybrids (F1 and reciprocals), together with the eight parent lines and six controls, were.. Read More»

Soybean genotype analysis for cyst nematode resistance
Authors: B.C.M. Juliatti, I.F. Beloti, L.C. Pena and F.C. Juliatti
Some species of soybean cultivars have the characteristic of resistance or alteration in survival skills, and perpetuation of nematodes (female index - FI), whose process is activated when the nematode parasitism starts and the development of new resistant cultivars is primordial to the preservation of plant productivity. The .. Read More»

Multivariate statistics applied to the reaction of common bean plants to parasitism by Meloidogyne javanica
Authors: L.N.S. Santos, P.D.S. Cabral, G.A.R. Neves, F.R. Alves, M.B. Teixeira1, F.N. Cunha1 N.F. Silva
The availability of common bean cultivars tolerant to Meloidogyne javanica is limited in Brazil. Thus, the present study aimed to evaluate the reactions of 33 common bean genotypes (23 landrace, 8 commercial, 1 susceptible standard and 1 resistant standard) to M. javanica, employing multivariate statistics to discriminate the ..

Indirect selection of industrial tomato genotypes that are resistant to spider mites (Tetranychus urticae)
Authors: J.E. Baier, J.T.V. Resende, M.V. Faria, K. Schwarz and L. Meert
Acyl sugars present in the tomato Solanum lycopersicum ‘LA-716’ accession confer good levels of resistance to arthropod pests. The objective of the present study was to select F2 plants from the interspecific cross Solanum pennellii ‘LA-716’ x Solanum lycopersicum ‘Redenção’ to assess resistance to spider .. Read More»

Aggressiveness of Pseudocercospora griseola strains in common bean genotypes and implications for genetic improvement
Authors: R. Pereira, E.A. Souza, Q.L. Barcelos, A.F.B. Abreu and S.S. Librelon
The fungus Pseudocercospora griseola, the causal agent of angular leaf spot in the common bean (Phaseolus vulgaris L.), exhibits a broad pathogenic variability that complicates the development of resistant cultivars. For breeding programs to successfully obtain common bean cultivars with durable resistance, knowing the aggressiveness of different strains,.. Read More»

Bayesian inference to study genetic control of resistance to gray leaf spot in maize
Authors: M. Balestre, R.G. Von Pinho, A.H. Brito
Gray leaf spot (GLS) is a major maize disease in Brazil that significantly affects grain production. We used Bayesian inference to investigate the nature and magnitude of gene effects related to GLS resistance by evaluation of contrasting lines and segregating populations. The experiment was arranged in a randomized block desi.. Read More»

Differential interactions between Curtobacterium flaccumfaciens pv. flaccumfaciens and common bean
Authors: S.C.D. Valdo, A. Wendland, L.G. Ara�ºjo, L.C. Melo, H.S. Pereira, P.G. Melo and L.C. Faria
Bacterial wilt of common bean caused by Curtobacterium flaccumfaciens pv. flaccumfaciens is an important disease in terms of economic importance. It reduces grain yield by colonizing xylem vessels, subsequently impeding the translocation of water and nutrients to the superior plant parts. The existence of physiological races i.. Read More»
