Genetic improvement is essential to achieve increments in maize (Zea mays L.) grain yield components. It may be obtained through crosses, which enable to exploit the effects of intervarietal heterosis, allelic complementarity, as well as gene actions and effects. This study estimated the components of variance and genetic para.. Read More»

Genetic analyses, phenotypic adaptability and stability in sugarcane genotypes for commercial cultivation in Pernambuco
Authors: J.A. Dutra Filho; T.C. Junior and D.E. Sim�µes Neto
In the present study, we assessed the agro-industrial performance of 22 sugarcane genotypes adaptable to edaphoclimatic conditions in production microregions in the State of Pernambuco, Brazil, and we recommended the commercial cultivation of select genotypes. The variables analyzed were as follows: sucrose percentage in cane .. Read More»

Molecular characterization of caj�¡, Spondias mombin (Anacardiaceae), by RAPD markers
Authors: A.T.B. Lima, V.A.B. de Souza, R.L.F. Gomes and P.S.C. Lima
The arboreal species Spondias mombin L. (Anacardiaceae) is widely distributed in Brazil, where the fruits, known by the common name of cajá, are an important commercial commodity. We evaluated genetic variability among 32 cajá accessions of the Germplasm Collection of Embrapa Meio-Norte using RAPD technique. Reac.. Read More»

RAPD analysis of the genetic diversity among accessions of Fabaceous forages (Poincianella spp) from the Caatinga
Authors: R.F.M. Mendes, R.B. Araujo Neto, M.P.S.B.C. Nascimento and P.S.C. Lima
Among members of the Fabaceae family, native to the Brazilian Caatinga, the species Poincianella pyramidalis and P. bracteosa exhibit particular potential as forage for cattle, sheep and goats. With the aim of establishing genetic relationships within Poincianella, random amplified polymorphic DNA analysis wa.. Read More»

Phenotype adaptability and stability of sugarcane genotypes in the sugarcane belt of the State of Pernambuco, Brazil
Authors: J.A. Dutra Filho; T.C. Junior and D.E. Sim�µes Neto
We assessed the agroindustrial performance of 25 sugarcane genotypes adapted to the edaphoclimatic conditions of the State of Pernambuco, Brazil, within the microregions Mata Norte, Mata Sul, Região Central, Litoral Norte, and Litoral Sul. The variables analyzed were POL tonnage per hectare, sugarcane tonnage per hectar.. Read More»

Genomic in situ hybridization in plants
Authors: G.S. Silva and M.M. Souza
Genomic in situ hybridization (GISH), which is a modification of fluorescent in situ hybridization, has been widely used in the study of plants. It has become one of the most important techniques for molecular cytogenetics. GISH is a technique that allows distinguishing the genomes in a cell. With this technique, it is possible to differentiate the genome.. Read More»
