Multivariate approach in Eucalyptus and its effects in the genotypes × environments interaction

Authors: Osmarino Pires Dos Santos, Ivan Ricardo Carvalho, Vinícius Jardel Szareski, Alan Junior De Pelegrin, Mauricio Horbach Barbosa, Francine Lautenchleger, Velci, Queiróz De Souza

The study aimed at the selection and evaluation of Eucalyptus spp. clones for the production of wood by means of multivariate statistical techniques. A total of 84 Eucalyptus clones were used belonging to the breeding program in Rio Grande do Sul, Brazil, in a randomized block design, with 20 replicates. The selection of clone.. Read More»

Resistance to Helicoverpa armigera mediated by zingiberene and glandular trichomes in tomatoes for industrial processing

Authors: J.F. Júnior, 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»

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»
