In Brazil, using combining ability of popcorn genotypes to achieve superior hybrids has been unsuccessful because the local genotypes are all members of the same heterotic group. To overcome this constraint, 10 lines (P1 to P10) with different adaptations to tropical or temperate edaphoclimatic environments were used to obtain.. Read More»

Identification and mapping of resistance genes to Phakopsora pachyrhizi in soybean (Glycine max L.) accession PI 594767-A
Authors: G.A.F. Rocha, D.P. Alves, J.C. Oliveira and S.H. Brommonschenkel
The goal of this study was to study resistance inheritance in the soybean (Glycine max L.) accession PI 594767-A to the Phakopsora pachyrhizi isolate PPUFV02, and map the resistance gene(s) identified using microsatellite markers. Crosses between PI 594767-A and the susceptible cultivar ‘Conquista’ gave rise to the segregating subpopulations 2.. Read More»

Genetic structure based on nuclear and chloroplast microsatellite loci of Solanum lycocarpum A. St. Hil. (Solanaceae) in Central Brazil
Authors: K. Martins, L.J. Chaves, R. Vencovsky and P.Y. Kageyama
Solanum lycocarpum (Solanaceae) is a woody species found in the Brazilian Cerrado. The flowers are pollinated by Xylocopa spp bees, and seeds are dispersed by mammals with distinct home range sizes. As a consequence, relative contributions of pollen and seeds to overall gene flow can vary according to different spatial scales... Read More»

Search for methylation-sensitive amplification polymorphisms in mutant figs
Authors: M.G.F. Rodrigues, A.B.G. Martins, B.W. Bertoni, A. Figueira and S. Giuliatti
Fig (Ficus carica) breeding programs that use conventional approaches to develop new cultivars are rare, owing to limited genetic variability and the difficulty in obtaining plants via gamete fusion. Cytosine methylation in plants leads to gene repression, thereby affecting transcription without changing the DNA sequence. Previous studies using random amp.. Read More»

Genetic control of agronomically important traits of pepper fruits analyzed by Hayman�s partial diallel cross scheme
Authors: A.R. Schuelter, G.M. Pereira, A.T. Amaral J�ºnior, V.W.D. Casali, C.A. Scapim, W.S. Barros and F.L. Finger
Pepper species of the genus Capsicum have been cultivated over centuries, producing both pungent and sweet fruit; the pungency is caused by alkaloids called capsaicinoids. Among the five cultivated species, Capsicum chinense is one of the most popular, being native to the Amazon basin. This species is characterized by a wide variety of fruit sizes, shapes an..

Inheritance of resistance to Meloidogyne incognita race 2 in the hot pepper cultivar Carolina Cayenne(Capsicum annuum L.)
Authors: Fausto de Souza-Sobrinho, Wilson Roberto Maluf, Luiz A.A. Gomes and Vicente Paulo Campos
Root-knot nematodes of the genus Meloidogyne are important pathogens affecting vegetable crop production in Brazil and worldwide. The pepper species Capsicum annuum includes both hot and sweet peppers; very little emphasis has been placed on breeding sweet peppers for nematode resistance. We report on the inheritance of resist.. Read More»
