The effects of encoding data in diversity studies and the applicability of the weighting index approach for data analysis from different molecular markers. Author(s): FERRÃO, L. F. V.; CAIXETA, E. T.; CRUZ, C. D.; SOUZA, F. de F.; FERRAO, M. A. G.; ZAMBOLIM, Z.; SAKIYAMA, N. S. The use of molecular markers to study genetic diversity represents a breakthrough in this area, because of the increase in polymorphism levels and phenotypic neutrality. Codominant markers, such as mi... ... Repository: BDPA Publication year: 2014

Morpho-agronomic, cytogenetic and molecular characterization of synthetic wheat accessions as a potential germplasm for plant breeding. Author(s): BRAMMER, S. P.; CARGNIN, A.; KIIHL, T. A. M.; RESENDE, T. T. de; CASASSOLA, A.; CECCON, C. C. Synthetic hexaploid wheat (AABBDD) is produced by using the tetraploid Triticum turgidum var. durum (AABB) and the diploid Aegilops tauschii (DD) as parents. This cross has allowed genetic variability... ... Repository: BDPA Publication year: 2021
Microbial diversity in an Oxisol under no-tillage and conventional tillage in southern Brazil. Author(s): BABUJIA, L. C.; SILVA, A. P.; NOGUEIRA, M. A.; HUNGRIA, M. ABSTRACT: The no-tillage (NT) system of soil management is recognized as more sustainable than conventional tillage (CT), with an important role played by soil microorganisms. The objective of this st... ... Repository: BDPA Publication year: 2014
Insect richness in dung patches of cattle raised in two livestock systems. Author(s): GUSMAO, M. R.; OLIVEIRA, M. C. de S.; NICODEMO, M. L. F.; PEZZOPANE, J. R. M. The negative impact of livestock breeding on the environment has been mitigated through the combination of pastures and trees, characterizing the silvopastoral systems (SPS), an alternative to convent... ...
