Genetic divergence among sweet corn lines estimated by microsatellite markers
Authors: A.D. Lopes1, C.A. Scapim2, C.A. Mangolin3 and M.F.P.S. Machado3
The purpose of this study was to analyze the genetic diversity of 15 sugary-1 sweet corn lines by microsatellite markers. One hundred pairs of simple sequence repeat primers that were mapped for field corn were tested. Of these primers, 15% were polymorphic, and all were selected for the evaluation. These primers identified a total of 39 alleles among the.. Read More»

Comparative analysis of phylogenetic relationships, morphologies, and pathogenicities among Curvularia lunata isolates from maize in China
Authors: T. Liu, F.Z. Zhao, Y.Y. Wang, J.M. Hou, L.Z. Liu, Y.Q. Shen, Z. Liu, H.T. Zhang and Y.H. Zuo
To understand the effects of disease-resistant maize varieties and new cropping systems on the population of Curvularia lunata, 52 isolates of C. lunata were collected in China from 2011 to 2013. The isolates were analyzed in terms of phylogenetic relationships, morphology, and pathogenicity. Phylogenetic analysis showed that .. Read More»

Comparison of coefficients and distance measurements in passion fruit plants based on molecular markers and physicochemical descriptors
Authors: C.B.M. Cerqueira-Silva1, C.B. Cardoso-Silva2, L.D.H.C.S. Concei�§�£o3, J.V.A. Nonato2, A.C. Oliveira2 and R.X. Corr�ªa3
We investigated seven distance measures and 14 similarity coefficients in a set of observations of variables of the ‘yellow’ passion fruit plant (Passiflora edulis Sims), submitted to multivariate analyses (distance, projection and grouping). Fourteen genotypes were characterized, based on DNA amplification with 16 random amplif.. Read More»

Genetic distances between popcorn populations based on molecular markers and correlations with heterosis estimates made by diallel analysis of hybrids
Authors: R.E.F. Munhoz1, A.J. Prioli1, A.T. Amaral J�ºnior2, C.A. Scapim1 and G.A. Simon1
Diallel analysis was used to obtain information on combining ability, heterosis, estimates of genetic distances by random amplified polymorphic DNA (RAPD) and on their correlations with heterosis, for the popcorn varieties RS 20, UNB2, CMS 43, CMS 42, Zélia, UEM J1, UEM M2, Beija-Flor, and Viçosa, which were crossed to obtain all possib..

Genetic divergence among Brazilian garlic cultivars based on morphological characters and AFLP markers
Authors: R.G.F. Morales J.T.V. Resende F.V. Resende C.A. Delatorre A.S.T. Figueiredo P.R. Da-Silva
Outside its centers of origin, garlic propagates only asexually. Since asexual reproduction leads to the absence of meiotic recombination, the main garlic cultivars available for cultivation have arisen from the accumulation of somatic mutations in early cultivars. Thus, it is common for a single clone to have different names in different regions. This st.. Read More»

Assessing genetic divergence in interspecific hybrids of Aechmea gomosepala and A. recurvata var. recurvata using inflorescence characteristics and sequence-related amplified polymorphism markers
Authors: F. Zhang Y.Y. Ge W.Y. Wang X.L. Shen X.Y. Yu
Conventional hybridization and selection techniques have aided the development of new ornamental crop cultivars. However, little information is available on the genetic divergence of bromeliad hybrids. In the present study, we investigated the genetic variability in interspecific hybrids of Aechmea gomosepala and A. recurvata var. recurvata using inflorescen.. Read More»

Comparison of methods for estimates of molecular genetic diversity in genus Croton: influence of coefficients, clustering strategies and data projection
Authors: M.M. Scaldaferri, J.S. Freitas, J.G.P. Vieira, Z.S. Gon�§alves, A.M. Souza and C.B.M. Cerqueira-Silva
We investigated 10 similarity (and disimilarity) coefficients in a set of 40 wild genotypes of Croton linearifolius subjected to analyses using hierarchical grouping methods, grouping methods by optimization and data projection in two-dimensional space. Genotypes were characterized by analyzing DNA polymorphism with t.. Read More»

Authors: P.E. Teodoro, F.E. Torres and A.M. Corr�ªa
The objectives of this study were to use mixed models to confirm the presence of genetic variability in 16 soybean genotypes, to compare clusters generated by artificial neural networks (ANNs) with those created by the Ward modified location model (MLM) technique, and to indicate parental combinations that hold promise for obtaining superior segregating p..
