Resistance to Helicoverpa armigera mediated by zingiberene and glandular trichomes in tomatoes for industrial processing
Authors: J.F. J�ºnior, J.T.V. Resende, A.A. da Silva, A. Gabriel, A.R. Zeist*, R. Favaro, D.A. Nascimento, R.A. Zeist and C.K. Camargo
The Helicoverpa armigera (Hübner) is a recent pest in Brazil, causing losses in tomato production in the Espírito Santo and Goiás states, in Brazil. A promising alternative to control this insect pest is the development of resistent tomato varieties. The breeding programs have aimed to introduce alleles of r.. Read More»

Morphological and molecular characterization of maize inbred lines showing variability for drought tolerance
Authors: Asima Gazal, F.A. Nehvi, Ajaz Ahmad Lone, Zahoor Ahmed Dar
A set of hundred maize inbred lines were analyzed for resilience to moisture stress for twenty-four traits related to maturity, morphological, physiological, yield, quality and root traits. Evaluation confirmed a wide range of variability revealing significant response of main effects (lines, irrigations and years and their re.. Read More»

The genetic diversity and population structure of Genipa americana L. in Northern Mato Grosso, Brazil
Authors: D.A.C. Ruzza, A.A.B. Rossi, R.B. Bispo, A.V. Tiago, J.S. Cochev, Fernando Saragosa Rossi and J.M. Fernandes
Genipa americana L. (Rubiaceae) is an Amazon region-natural species, which may be subject to inbreeding, since it grows in fragmented environments. The aim of the current study is to assess the genetic diversity and population structure of three G. americana populations naturally grown in Northern Mato Grosso State using SSR m.. Read More»

Identification, Characterization, and Phylogenetic analysis of Pigeon pea (Cajanus cajan L. Mill sp.) Resistance Gene Analogs using PCR cloning and in silico methods
Authors: Ikechukwu O. Agbagwa, Prakash G. Patil, Alok Das, Khela R. Soren, Indra P. Singh, Sushil K. Chaturvedi, Nagaswamy Nadarajan
Pigeon Pea (Cajanus cajan), an important grain legume, is susceptible to Fusarium wilt (FW), sterility mosaic disease (SMD), and Phytophthora blight. Identification of resistance gene analogs (RGAs) is important for development of resistant varieties. In this study, degenerate primers targeting nucleotide binding sites (NBS) o.. Read More»

Adaptability and stability of cotton cultivars (Gossypium hirsutum L. race latifolium H.) using factor analytic model
Authors: J. J. Nuvunga, L. A. Oliveira, C. P. Silva, A. K. A. Pamplona, A. Q. Silva, E. G. Moura, M. P. Maleia, M. Balestre
To build up efficient strategies in plant breeding programs, it is requested a certain level of knowledge about the genotype–by-environments interaction (GEI) effects over the crop to be improved. One efficient way to gather this information is using linear mixed models using a parsimonious structure of GEI pattern such .. Read More»

Estimate of natural cross-pollination rate of Capsicum annuum using a codominant molecular marker associated with fruit pungency
Authors: EV Justino, MEN Fonseca, ME Ferreira, LS Boiteux, PP Silva, WM Nascimento
The production of seeds with high genetic quality requires accurate estimates of the natural cross-pollination rate in cultivated Capsicum species. This is important in order to establish the most suitable isolation distance among fields of distinct genotypes, to minimize the risk of genetic contamination and to ensure that th.. Read More»
